Question 1

Hominin

Answer 1

The term used for humans and their ancestors after the split with chimpanzees and bonobos.

Question 2

Holism

Answer 2

By using a holistic approach, anthropologists ask how different aspects interact with and influence one another.

Question 3

Primatology

Answer 3

Primatologists study the anatomy, behavior, ecology and genetics of living and extinct nonhuman primates, including apes, monkeys, tarsiers, lemurs, and lorises, because nonhuman primates are our closest living biological relatives.

Question 4

Paleoanthropology

Answer 4

Paleoanthropologists study human ancestors from the distant past to learn how, why, and where they evolved. They have to rely on physical evidence. This evidence includes fossilized remains (particularly fossilized bones), artifacts such as stone tools, and the contexts in which these items are found.

Question 5

Bioarcheology

Answer 5

study human skeletal remains and the soils and other materials found in and around the remains.

Question 6

Molecular Anthropology

Answer 6

Molecular anthropologists use molecular techniques (primarily genetics) to compare ancient and modern populations and to study living populations of humans and nonhuman primates.

Question 7

Forensic Anthropology

Answer 7

Forensic anthropologists use many of the same techniques as bioarchaeologists to develop a biological profile for unidentified individual

Question 8

Human biology

Answer 8

tends to explore how the human body is impacted by different physical environments, cultural influences, and nutrition. These include studies of human variation or the physiological differences among humans around the world.

Question 9

Australopithecus afarensis

Answer 9

lived from about 3.9–2.9 million years ago in the Pliocene of East Africa.

Question 10

Homology

Answer 10

When two or more taxa share characteristics because they inherited them from a common ancestor.

Question 11

Monogenism

Answer 11

the idea that all people share a common single origin.

Question 12

Polygenism

Answer 12

The idea that different peoples have different origins. Helped people to rationalize slavery because they could say that africans and europeans had no common ancestry

Question 13

Descent with modifictation

Answer 13

Darwin’s term for what we now call “evolution”, in which animals and plants look different from their ancestors.

Question 14

Natural Selection

Answer 14

an evolutionary process that occurs when certain phenotypes confer an advantage or disadvantage in survival and/or reproductive success. This is one of the forces of evolution.

Question 15

Phenotype

Answer 15

A set of outwardly observable characteristics for an individual.

Question 16

morphology

Answer 16

physical characteristics

Question 17

The Pleistocene epoch

Answer 17

between 1.8 million years ago (mya) and 11,000 years ago (kya).

was a time of great climatic upheaval.

Altered between glacial periods and warmer periods

archaic Homo sapiens

Question 18

interglacials

Answer 18

opposite of glacial periods in the Middle Pleistocene.

increased rainfall and a higher temperature that caused glaciers to melt.

These are marked by glacial retreat. Sea levels also increase and flooding of exposed coastlines and continental connections occurs. Plant and animal communities shift accordingly.

Question 19

archaic Homo sapiens

Answer 19

Transitional spiecies between Homo erectus and Homo sapiens Increased brain size, decrease of canine size, reduction of the skull to become bipedal,

Question 20

Neanderthals

Answer 20

Found in Germany.

lived between 150,000 and 35,000 years ago.

Fossils have only been found in Western Eruope, the Middle East, and western Asia.

Adapted to cold weather, long and low skull shape that is slightly wider, large noses, cheekbones are notably larger, brow ridges less arched than archaic Homo sapiens, thick bones with barrel chest size, Reduced jaw resulting in retromolar gap.

Question 21

Mousterian tools

Answer 21

The stone tool industry of Neanderthals and their contemporaries in Africa and Western Asia. Mousterian tools are known for a diverse set of flake tools, which is different than the large bifacial tools of the Acheulean industry.

Mousterian tools were significantly smaller, thinner, and lighter than Acheulean handaxes and formed a true toolkit.

Question 22

Levallois technique

Answer 22

Used by Archaic Homo sapiens, including Neanderthals. Involves the preparation of a core and striking edges off in a regular fashion around the core. Then a series of similarly sized pieces can be removed, which can then be turned into different tools.

Question 23

The Middle Stone Age: Neanderthal Contemporaries in Africa

Answer 23

dates to between 300,000 and 30,000 years ago

Similar to modern Homo sapiens

Larger more intense fires that required exploration of dry wood, use of seafood in diets, manufacture of bone tools, use of adhesive and compound tools (e.g., hafted tools), shell bead production, engraving, use of pigments (such as ochre), and other more advanced tool-making technology (e.g., microlithics).

More complex than Neanderthals because: Response to climate change, increased use of language, marine resources, competition among other groups, and diverse habitats

Question 24

Denisovans

Answer 24

found a child’s finger bone and an adult tooth from Denisova Cave

adaptations for life at high altitudes Prevented them from developing altitude sickness and hypoxia

Share DNA with modern Melanesians, Polynesians and modern Asian and Native Americans Interbreeding between Denisovans and humans

Question 25

Out-of-Africa Hypothesis

Answer 25

Modern humans originated in Africa, replacing archaic populations found elsewhere in the Old World. Making interbreeding impossible. Admixture resulting from gene flow would not have been possible according to this model.

Question 26

Multiregional Continuity Hypothesis

Answer 26

tates that modern Homo sapiens are directly derived from Homo erectus and evolved in place after Homo erectus left Africa and populated areas in Asia and Europe.

Question 27

Assimilation Hypothesis

Answer 27

modern humans originated in Africa, spreading outward into Asia and Europe and interbreeding with more archaic forms they encountered along the way.

Question 28

Homo naledi

Answer 28

Found in 2013 in a cave in Johannesburg, South Africa

sagittal keel and large brow, a well-developed frontal lobe, yet the brain size is significantly smaller than its counterparts, at approximately 500 cc (560 cc for males and 465 cc for females). The teeth have a reduction in overall tooth size.

Had unique shoulder anatomy and curved fingers, indicating similarities to tree-dwelling primates.

lived between 335,000 and 236,000 years ago alongside Homo sapiens

Superman’s Crawl

Question 29

Homo floreisenis

Answer 29

found in Florence in 2003

Found nine individuals

A sagittal keel, an arching brow ridges and nuchal torus, and the lack of a chin.had a brain size that was remarkably small at 400 cc

recent genetic studies suggest a common ancestor with modern humans that predates Homo erectus.

they had insular dwarfing

have lived on the island between 100,000 and at least 60,000 years ago.

May have lived at the same time as modern Homo sapiens

Question 30

insular dwarfing

Answer 30

A form of dwarfism that occurs when a limited geographic region, such as an island, causes a large-bodied animal to be selected for a smaller body size.

Question 31

Glaciation

Answer 31

Ice age, the water levels were lower because most of it was ice sheets or large glaciers. The water cycle experiences limited runoff as water evaporates from the seas, precipitates (often as snow and ice), and accumulates in glaciers with little precipitation melting as runoff.

Question 32

retromolar gap

Answer 32

A space behind the last molar and the end of the jaw. This is a feature present only on Neanderthals. It also occurs through cultural modification in modern humans who have had their third molars, or wisdom teeth, removed.

Question 33

Cranial Traits (archaic Homo sapiens vs modern Homo sapiens)
