How do you situate Anthropology in Social Sciences? (10Marks 2013)
Anthropology is situated in the social sciences as a discipline that bridges the gap between the humanities and natural sciences. It encompasses the study of human societies, cultures, and their development. Unlike other social sciences that often focus on specific aspects of human behavior (e.g., economics, political science), anthropology offers a holistic approach, integrating cultural, biological, archaeological, and linguistic perspectives. This interdisciplinary nature allows anthropology to provide comprehensive insights into human diversity, social structures, and cultural dynamics, making it a cornerstone of social science research.
Differences between Social Anthropology and Sociology. (10M 2016)
Social Anthropology and Sociology both study societies but differ in focus and methodology. Social Anthropology emphasizes cross-cultural comparisons, often through ethnographic fieldwork, and explores cultural practices, rituals, and social structures in diverse societies. Sociology typically focuses on contemporary, complex societies, using quantitative methods like surveys and statistical analysis to study social institutions, relationships, and problems. While social anthropology seeks to understand cultural diversity and universality, sociology often examines social patterns and issues within a specific societal context.
Archaeological Anthropology (10Marks 2015,1992)

Linguistic Anthropology studies the relationship between language and culture, focusing on how language shapes communication, social identity, group membership, and cultural beliefs. It explores language use in various social contexts, language acquisition, and the impact of language on cognition. This subfield examines linguistic diversity, language change, and the role of language in maintaining or challenging power dynamics within societies. By analyzing how language influences and reflects social life, linguistic anthropology contributes to broader understandings of cultural practices, social structures, and human interaction.
Social & Cultural Anthropology (10Marks 1994)
Social and Cultural Anthropology are intertwined fields that explore human societies and cultures. Social Anthropology focuses on social structures, relationships, and institutions, analyzing how societies organize themselves and maintain social order. Cultural Anthropology examines cultural beliefs, practices, and artifacts, studying how people understand and interpret their world. Both fields use ethnographic methods to provide deep insights into human behavior and cultural diversity. By studying social norms, rituals, and cultural expressions, these subfields contribute to a comprehensive understanding of human life and cultural variation.
Applied Anthropology (1990)
Applied Anthropology uses anthropological methods and insights to address real-world problems and issues. It involves the application of anthropological knowledge to areas such as public health, development, education, and business. Applied anthropologists work in diverse settings, including government agencies, NGOs, and private sector organizations, to design and implement policies, programs, and interventions. They aim to improve social outcomes by understanding cultural contexts and working collaboratively with communities. This practical orientation makes applied anthropology a valuable tool for fostering social change and development.
Theme of Linguistic Anthropology (1989)
The central theme of Linguistic Anthropology is the intricate relationship between language and culture. This subfield explores how language shapes and is shaped by social life, influencing identity, power dynamics, and cultural practices. It investigates language use in various contexts, such as everyday conversation, rituals, and political discourse. Linguistic anthropologists study language acquisition, multilingualism, and language change, highlighting how linguistic practices reflect and construct social realities. The theme encompasses the role of language in socialization, cultural transmission, and the maintenance of social structures.
New Physical Anthropology (1989)
New Physical Anthropology, also known as Bioanthropology, emphasizes the biocultural approach, integrating biological and cultural perspectives to study human variation and evolution. It focuses on understanding the interplay between biology and culture in shaping human health, behavior, and adaptation. This approach examines genetic and environmental influences on human populations, employing advanced techniques in genetics, paleoanthropology, and forensic anthropology. New Physical Anthropology highlights the importance of considering both biological and cultural factors in addressing questions about human diversity, evolution, and contemporary health issues.
What is the hominization process? Discuss the major trends in human evolution with the help of suitable examples and illustrations. (20M–2023)
Hominization is the evolutionary process that led to the emergence of anatomically modern humans from our primate ancestors. Major trends in human evolution include bipedalism, as seen in Australopithecus afarensis; increased brain size, as evidenced by Homo habilis; tool use and cultural development, noted in Homo erectus; and the development of complex language and societies, characteristic of Homo sapiens. Illustrations like the progression from the early hominins to modern humans and fossil evidence, such as the Laetoli footprints and the skull of Homo neanderthalensis, highlight these evolutionary milestones.
Explain the genetic mechanisms of micro and macro evolution. (15 Marks, 2021)
Microevolution refers to small-scale evolutionary changes within a population, primarily driven by genetic mechanisms like mutation, gene flow, genetic drift, and natural selection. Macroevolution involves larger-scale evolutionary changes that result in the formation of new species and higher taxonomic groups, driven by mechanisms such as speciation events and long-term environmental changes. For example, genetic drift can cause allele frequency changes in small populations, while speciation can occur through reproductive isolation mechanisms. Macroevolutionary patterns are observed in the fossil record, showing the gradual emergence of new species over time.
Elucidate how Darwin and post-Darwin theories of evolution resulted in the development of the Synthetic theory of evolution. (15 M -2020)
Darwin’s theory of evolution by natural selection laid the foundation for understanding how species adapt and evolve. Post-Darwinian theories, incorporating Mendelian genetics, elucidated the mechanisms of heredity. The Synthetic theory of evolution, also known as the Modern Synthesis, integrates Darwinian natural selection with Mendelian genetics, explaining evolution as a gradual process driven by genetic variation, mutation, gene flow, genetic drift, and natural selection. This comprehensive framework reconciles microevolutionary processes with macroevolutionary patterns, providing a unified explanation for the continuity and diversification of life.
Explain the biological changes that made human beings capable of making cultures. (20 marks-2018)
Biological changes that enabled humans to develop cultures include the evolution of bipedalism, which freed the hands for tool use; increased brain size, particularly in the frontal cortex, enhancing cognitive abilities; the development of complex vocal apparatus for speech; and the refinement of fine motor skills. These adaptations allowed early humans to create and use tools, develop language, form social structures, and transmit knowledge across generations. For example, the archaeological record shows the use of tools by Homo habilis and the development of art and symbolic behavior by Homo sapiens, demonstrating the interplay between biological evolution and cultural complexity.
Critically examine Darwin’s theory of evolution in understanding Evolution. (15 Marks 2015)
Darwin’s theory of evolution by natural selection is fundamental in understanding biological evolution. It explains how organisms adapt to their environment through differential survival and reproduction of individuals with advantageous traits. However, it has limitations. Darwin’s theory did not explain the mechanisms of inheritance, which were later clarified by Mendelian genetics. Additionally, modern evolutionary biology recognizes other factors like genetic drift, gene flow, and mutation in shaping evolutionary processes. Despite its limitations, Darwin’s theory provides a critical framework for studying evolution, highlighting the importance of variation and adaptation in the natural world.
Biological Evolution of early man (1997)
The biological evolution of early man involves a series of anatomical and physiological changes over millions of years. Key developments include the transition to bipedalism in Australopithecus, the use of tools by Homo habilis, increased brain size and complexity in Homo erectus, and the emergence of Homo sapiens with advanced cognitive abilities. Fossil evidence, such as the skeletal remains of Lucy (an Australopithecus afarensis) and the tools of Homo habilis, provides insights into these evolutionary milestones. These changes facilitated improved mobility, tool use, social organization, and cultural development, setting the stage for the rise of modern humans.
How Darwinism differs from the synthetic theory of organic evolution? (1994)
Darwinism, or Darwin’s theory of evolution, focuses on natural selection as the primary mechanism for evolution, emphasizing the survival and reproduction of individuals with favorable traits. The Synthetic theory of evolution, or Modern Synthesis, expands on Darwinism by integrating Mendelian genetics, which explains how traits are inherited and varied. The Synthetic theory incorporates other mechanisms like genetic drift, gene flow, and mutation, providing a more comprehensive understanding of evolutionary processes. While Darwinism highlights natural selection, the Synthetic theory offers a broader perspective, explaining both microevolutionary changes within species and macroevolutionary patterns across species.
What is the Synthetic Theory of Evolution? Discuss how this theory helps us in understanding the evolutionary mechanism. (1993)
The Synthetic Theory of Evolution, or Modern Synthesis, integrates Darwin’s theory of natural selection with Mendelian genetics, forming a unified framework for understanding evolution. It explains how genetic variation arises through mutations and recombination, and how these variations are acted upon by natural selection, genetic drift, gene flow, and other factors. This theory helps us understand evolutionary mechanisms by demonstrating how microevolutionary processes (changes within populations) lead to macroevolutionary patterns (formation of new species and higher taxa). It provides a comprehensive explanation of how evolutionary changes accumulate over time, resulting in the diversity of life we observe today.
What is organic evolution? Give evidences for human evolution. (1992)
Organic evolution refers to the process by which living organisms undergo genetic changes over successive generations, leading to the diversity of life forms. Evidence for human evolution includes fossil records, such as Australopithecus afarensis (e.g., Lucy), Homo habilis, and Homo erectus; comparative anatomy, showing similarities between human and primate skeletal structures; genetic evidence, indicating common ancestry with other primates; and archaeological findings, such as tools and artifacts that trace the development of early human technology and culture. These pieces of evidence collectively support the evolutionary history of humans from common ancestors shared with other primates.
What is Organic Evolution? Describe the theories of organic evolution. (1991)
Organic evolution is the process of gradual change in living organisms over time, leading to the emergence of new species and the diversity of life. Theories of organic evolution include Lamarckism, which proposes that traits acquired during an organism’s lifetime can be passed on to offspring; Darwinism, which emphasizes natural selection and the survival of the fittest; and the Synthetic Theory of Evolution, which combines natural selection with Mendelian genetics, incorporating factors like mutation, genetic drift, and gene flow. These theories explain the mechanisms by which evolutionary changes occur, contributing to our understanding of the origin and development of species.
Theory of organic evolution (1985)
The theory of organic evolution explains how life evolves through gradual changes over time, resulting in the diversity of species. Key theories include Lamarckism, which suggests that acquired characteristics can be inherited; Darwinism, which posits natural selection as the primary mechanism of evolution; and the Synthetic Theory of Evolution, which integrates natural selection with genetic principles. The latter theory incorporates multiple factors such as mutation, genetic drift, and gene flow, providing a comprehensive explanation of evolutionary processes. These theories collectively contribute to our understanding of the mechanisms driving the evolution and diversification of life on Earth.
Micro evolution (1990)
Microevolution refers to small-scale evolutionary changes within a population over a relatively short period. These changes are driven by genetic mechanisms such as mutation (random changes in DNA), gene flow (exchange of genes between populations), genetic drift (random fluctuations in allele frequencies), and natural selection (differential survival and reproduction of individuals with advantageous traits). An example of microevolution is the development of antibiotic resistance in bacteria, where genetic mutations confer resistance, and natural selection ensures that resistant bacteria survive and proliferate. Microevolutionary processes contribute to the adaptation and variability within species.
Elucidate the theory of Evolution as put forward by Lamarck.
Lamarck’s theory of evolution, known as Lamarckism, proposes that organisms evolve through the inheritance of acquired characteristics. According to Lamarck, traits developed during an organism’s lifetime as a response to environmental changes can be passed on to offspring. For example, he suggested that giraffes evolved long necks because their ancestors stretched their necks to reach higher leaves, and this trait was inherited by subsequent generations. Although Lamarckism was eventually supplanted by Darwinian evolution and modern genetics, it was significant as one of the first attempts to explain evolutionary processes. Modern understanding of genetics has refuted Lamarck’s mechanism of acquired inheritance.
Give a critical account of the processes of organic evolution and explain how they contribute to speciation. (1988)
Organic evolution involves processes such as mutation, natural selection, genetic drift, and gene flow. Mutation introduces new genetic variations; natural selection favors traits that enhance survival and reproduction; genetic drift causes random changes in allele frequencies, especially in small populations; gene flow transfers genes between populations. These processes contribute to speciation by creating genetic divergence between populations. When populations become
Biological evolution and concept of new Physical Anthropology (1986)
Biological evolution refers to the process by which species change over time through genetic variation and natural selection. The concept of New Physical Anthropology, or Bioanthropology, integrates biological and cultural perspectives to study human evolution and diversity. It emphasizes the biocultural approach, examining how biological factors (like genetics and physiology) and cultural practices (like diet and social behavior) interact. New Physical Anthropology employs modern techniques in genetics, paleoanthropology, and forensic anthropology to understand human evolution, adaptation, and variation. This interdisciplinary approach provides a comprehensive understanding of human biology in the context of cultural and environmental factors.
Lamarckism & Darwinism (1986)
Lamarckism posits that organisms can pass on traits acquired during their lifetime to their offspring. For example, Lamarck believed that giraffes’ long necks evolved because ancestors stretched their necks to reach higher leaves, and this trait was inherited. Darwinism, on the other hand, is based on natural selection, where individuals with advantageous traits are more likely to survive and reproduce, passing these traits to the next generation. Darwin’s theory does not involve the inheritance of acquired traits but rather emphasizes variation and differential reproductive success. While Lamarck’s ideas were foundational, Darwin’s theory is supported by genetic evidence and forms the basis of modern evolutionary biology.
Discuss different forms of primate social organisation. (15 Marks, 2022)
Primate social organization varies widely and includes solitary, monogamous, polygynous, and multi-male/multi-female groups. Solitary species, like orangutans, have minimal social interactions. Monogamous pairs, such as gibbons, form long-term bonds and live with their offspring. Polygynous groups, common among gorillas, consist of one male with multiple females and their young. Multi-male/multi-female groups, seen in chimpanzees and baboons, feature complex social hierarchies and alliances. These social structures influence primate behavior, mating strategies, and survival, highlighting the adaptability of primates to diverse ecological niches.
The losses and gains of erect posture (10 Marks, 2021)
Erect posture, or bipedalism, offered significant evolutionary advantages, including energy-efficient locomotion, freeing of hands for tool use and carrying, and improved field of vision. However, it also came with costs, such as increased stress on the spine and lower limbs, leading to back pain and joint issues. The anatomical adaptations necessary for bipedalism, such as changes in the pelvis, spine, and lower limbs, represent a trade-off between the benefits of upright walking and the associated physical challenges. Overall, the gains in mobility, tool use, and environmental adaptation outweighed the drawbacks, driving the evolutionary success of bipedal hominins.
Jane Goodall’s contributions in studying primate behaviour. (10 M, 2020)
Jane Goodall revolutionized the study of primate behavior through her long-term research on wild chimpanzees in Gombe, Tanzania. She discovered that chimpanzees use tools, exhibit complex social behaviors, and have distinct personalities. Her observations of hunting, warfare, and maternal care among chimpanzees challenged previous assumptions about primate and human behavior. Goodall’s work emphasized the importance of field studies, empathy, and patience in understanding animal behavior, significantly contributing to primatology and anthropology. Her findings have influenced conservation efforts and enhanced our understanding of the evolutionary roots of human behavior.
Illustrate with examples the various types of locomotion pattern among non-human primates. (15 M, 2020)
Non-human primates exhibit diverse locomotion patterns, including arboreal quadrupedalism, terrestrial quadrupedalism, brachiation, knuckle-walking, and bipedalism. Arboreal quadrupedalism is seen in monkeys like capuchins, who move on all fours in trees. Terrestrial quadrupedalism, as observed in baboons, involves walking on all fours on the ground. Brachiation, used by gibbons, involves swinging from branch to branch using their arms. Knuckle-walking, characteristic of chimpanzees and gorillas, involves walking on the knuckles of the hands. Bipedalism, though rare, is occasionally observed in species like bonobos, highlighting the evolutionary diversity and adaptability of primate locomotion.
Adaptive primate radiation (2019-10 marks), (1995)
Adaptive primate radiation refers to the evolutionary diversification of primates into various ecological niches. This process, driven by natural selection, led to the development of diverse adaptations in morphology, behavior, and diet. For example, the differentiation of lemurs in Madagascar showcases a range of adaptations to different habitats, from arboreal to terrestrial lifestyles. The radiation of New World monkeys resulted in a variety of species with distinct adaptations, such as prehensile tails in spider monkeys for arboreal life. Adaptive radiation in primates demonstrates the ability to exploit different ecological opportunities, contributing to the wide diversity seen in the primate order today.
Discuss the evolutionary significance of bipedalism and erect posture. (20 marks, 2019)
Bipedalism and erect posture are significant evolutionary developments in hominins, providing numerous adaptive advantages. Bipedalism allowed for energy-efficient long-distance travel, improved thermoregulation, and the ability to see over tall grasses. It also freed the hands for tool use, carrying objects, and complex manipulations, fostering technological and cultural advancements. Anatomical changes, such as the restructuring of the pelvis, spine, and lower limbs, facilitated bipedal locomotion. These adaptations not only distinguished early hominins from other primates but also set the stage for further evolutionary developments, such as increased brain size and complex social behaviors, crucial for the emergence of Homo sapiens.
Bring out the comparative anatomical features of man and apes. Discuss their evolutionary significance. (2017)
Humans and apes share many anatomical features, such as opposable thumbs, binocular vision, and a similar dental formula, reflecting their common ancestry. However, key differences include bipedalism in humans, resulting in a distinct pelvic structure and spinal curvature, and a larger brain size relative to body size in humans, associated with advanced cognitive abilities. Apes, like chimpanzees, have longer arms and stronger shoulder muscles adapted for arboreal locomotion. These anatomical differences highlight the divergent evolutionary paths, with humans evolving traits for upright walking, tool use, and complex social interactions, while apes retained adaptations for life in trees and complex social structures within their environments.
Explain the skeletal changes due to erect posture and their implications. (2016)
The transition to erect posture in humans led to significant skeletal changes, including a shorter, broader pelvis, an S-shaped spine for better weight distribution, and a repositioned foramen magnum at the base of the skull. The lower limbs became longer relative to the arms, with adaptations in the femur, knee, and foot for stability and efficient bipedal locomotion. These changes improved energy efficiency in walking and running, freed the hands for tool use, and allowed for greater height and visibility in open landscapes. However, they also increased the risk of lower back pain, joint issues, and complications in childbirth, reflecting the trade-offs associated with bipedalism.
Elucidate the skeletal differences between humans and chimpanzees. (15Marks, 2014)
Humans and chimpanzees share a common ancestor but exhibit distinct skeletal differences. Humans have a larger braincase, a vertical forehead, and a less protruding face. The foramen magnum in humans is centrally positioned at the skull base for upright posture. The pelvis in humans is shorter and broader, supporting bipedalism. Human femurs are angled inward, and feet have arches for shock absorption. In contrast, chimpanzees have a smaller braincase, more pronounced brow ridges, and a more prognathous face. Their pelvis is longer and narrower, and their arms are longer relative to their legs, adapted for knuckle-walking and arboreal locomotion. These differences underscore adaptations to bipedalism in humans and arboreal life in chimpanzees.
Role of Primatology in Anthropological studies. (10Marks, 2013)
Primatology plays a crucial role in anthropological studies by providing insights into the behavior, social structures, and evolutionary history of our closest relatives. Studying non-human primates helps anthropologists understand the origins and development of human traits, such as social organization, communication, and tool use. Primatology also informs us about the ecological adaptations and evolutionary pressures that shaped primate evolution, offering comparative data to reconstruct the behavior and lifestyle of early hominins. Additionally, conservation efforts in primatology contribute to preserving biodiversity and understanding the impact of environmental changes on primate populations, which parallels human environmental challenges.
Discuss the anatomical changes that occurred in Man due to erect posture. (1998)
Erect posture in humans led to several anatomical changes: the spine developed an S-shape for balance; the pelvis became shorter and wider for bipedal stability; the foramen magnum moved to a more central position under the skull; the femur angled inward for efficient bipedal locomotion; and the feet evolved arches and aligned toes for shock absorption and forward propulsion. These adaptations facilitated upright walking, freeing the hands for tool use and manipulation. However, they also introduced challenges, such as increased stress on the lower back and joints, highlighting the evolutionary trade-offs associated with bipedalism.
Discuss primate locomotion with special reference to adaptation to arboreal life. (1996)
Primates exhibit diverse locomotion patterns, especially adapted for arboreal life. Arboreal quadrupedalism, seen in many monkeys, involves moving on all fours among tree branches, supported by a strong grip and flexible joints. Brachiation, as used by gibbons, involves swinging from branch to branch using elongated arms and a strong shoulder girdle. Clinging and leaping, observed in lemurs, require powerful hind limbs for jumping between trees. These adaptations, including prehensile tails in some New World monkeys, enhance balance and mobility in complex arboreal environments, illustrating the evolutionary flexibility and specialization of primates for life in the trees.
Primate (1994)
Primates are a diverse order of mammals characterized by advanced cognitive abilities, complex social behaviors, and varied locomotion patterns. They are classified into two suborders: Strepsirrhines, including lemurs and lorises, and Haplorhines, which include tarsiers, monkeys, and apes. Primates typically have large brains relative to body size, forward-facing eyes for depth perception, and grasping hands and feet with opposable thumbs or big toes. Their dentition is adapted for an omnivorous diet. Primates inhabit diverse environments, from tropical forests to savannas, and their social structures range from solitary to complex multi-member groups, highlighting their adaptability and evolutionary success.
