BioAnthro Midterm Flashcards
Subfields of BioAnthropology
Human biology - Study of human genetics, variation within our species, and how our species is affected by the evolutionary process.
Forensic Anthropology - Application of knowledge and methods of skeletal analysis to assist in legal investigations.
Primatology - Study of living primates, particularly their similarities and differences and why those similarities and differences might exist.
Paleoanthropology - Study of the anatomy and behavior of humans and our extinct relatives.
multi-field approaches
Interdisciplinary partnerships allow paleoanthropologists to gain a more complete picture of the past
Biocultural Perspective
A research approach that recognizes the close relationship between human biology and culture and attempts to study these two forces simultaneously
Structure of science
Science is divided into disciplines:
Historical (natural philosophy)
Modern (branches of science)
Different Approaches:
Field researchers
Experimentalists
Theorists
hypotheses
A testable explanation of the researchers observations
theoretical framework
the structure of a study that links the theory concepts to the study variables; a section of a research article that describes the theory used
observations
Scientists can make observations of a phenomena directly or they can use observations of phenomena made by other scientists from previous research
Testing and retesting
Scientific theory is open to reinterpretation and rejections. Scientists may also improve this research by new hypotheses.
Data
the hypothesis is actually tested
Earnest Hooton (1887-1954)
racial classification
W.W. Howells
Took Hooton’s position at Harvard after his death. Studied human variation and came up with the dataset that disproves race.
Carleton Coon (1904-1981)
- Student of Hooton
- The Origin of Races (1962): modern human ‘races’ were the result of local populations of
Homo erectus evolving into Homo sapiens at different times; Europeans were first and therefore superior; book condemned by the American Anthropological Association the year it was published
Ashley Montague
Argues that the concept of race is wrong and meaningless- man’s most dangerous myth. “Scientific” definitions of race can’t capture human variation on complexity of evolutionary history
Sherwood Washburn (1911-2000)
pioneer in the primatology field, the study of primates in their natural habitats
Carolus Lineaus
Father of taxonomy
Typology
a classification according to general type, especially in archaeology, psychology, or the social sciences.
Hierarchy of progress
Idea that Evolution has occurred over time. Europeans believed that evolution was evolving for the better.
Samuel G. Morton (1799-1851)
Philadelphia doctor in early-19th century, he viewed brain size as criteria for intelligence. He collected over 6000 skulls to measure cranial capacity to determine brain size. He concluded that African and Native American were inferior races and his results fed the pro-slavery forces of the 19th century. He worked to justify and naturalize inequality along racial and cultural lines.
Ales Hrdlicka (1869-1943)
a classification according to general type, especially in archaeology, psychology, or the social sciences.
Evolution
Change over time; the process by which modern organisms have descended from ancient organisms
Biological evolution
The change in inherited traits over successive generations in populations of organisms.
who, what, when;
who- organisms, what- change in traits over populations over time, when- beginning of time to now, it is a change over a long period of time
units of evolution and selection;
Unit of Evolution is the Population
–Individuals cannot evolve.
Unit of Selection is the individual
–Selection works on an individual’s phenotype
Mutation
change in a DNA sequence that affects genetic information
natural selection
The process whereby organisms better adapted to their environment tend to survive and produce more offspring.
gene flow;
Movement of alleles into or out of a population due to the migration of individuals to or from the population
genetic drift;
Random Changes in allele frequencies in a population from generation to generation.
random versus non-random processes
Random - Random sampling is a sampling technique where each sample has an equal probability of getting selected
Non-Random - Non-random sampling is a sampling technique where the sample selected will be based on factors such as convenience, judgement and experience of the researcher and not on probability
