Into Australia and Europe
Northern Asians crossed Bering Strait to New World

2

Arrived in Australia
Boats still required
Mango Man skeleton found, fairly heavy brows
Kow Swamp Skull more modern

3

short, 1 meter
may or may not represent new species
may had undergone island dwarfism
individual with microphaly, brain fails to develop properly

4
Q

A

Arrived for N Asia through Bering Strait called Paleoindians
Pre-Clovis Culture, large spear points
Clovis complex culture, large fluted, bifacial stone points

5
Q

Shovel shaped incisors

A

posterior aspect has varying degrees of concavity

6

Kennewick incisors

A

more robust and less rounded, than the more gracile modern Indian skulls

7
Q

Hoyo Negro

A

oldest known human fossil of New World

teenage girl Naia in Yucatan Peninsula

8
Q

With agriculture, teeth have

A

become smaller and weaker because of softer foods

need for braces

9
Q

Malocclusions

A

jaw doesn’t close correctly with teeth aligned, creating crooked teeth
Follows Wolf’s Law of bone recession

10
Q

15,000-11,000 ya

A

foraging and fire use

plant domestication begins

11
Q

11,000-6,000 ya

A

small to large scale farming

plants are well domesticated

12
Q

6,000-Present

A

full blown agriculture

plants are domesticated

13
Q

What age begins with plant and animal domestication

A

neolithic age (new Stone Age)

14
Q

Agricultural Diffusion timeline

A
Southwest Asia
Central Mexico
South Central Andes
North China
South China
Eastern US
Sub-Sharan Africa
15
Q

Temperate and Tropical plants

A

Temperate: C3 plants (no carbon 13): Wheat, barley, rye, rice
Tropical: C4 plants (uptakes carbon 13): Corn, millet, sorghum
Can be dated in teeth

16

one of the earliest cities
body found in fetal position like le Chapelle aux Saints
these early Neolithic humans formed

17

A

Corn/Maize domesticated spread to American Southwest and Atlantic coast

19

A

dogs, goats, sheep, cattle, and pigs

20
Q

Neolithic Demographic Transition

A
high birthrate
2-3 million
300 million by 2000 ya
1 billion by 1850
>7 billion today
leads to soil erosion, deforestation, overgrazing
21

Humans cooperate or compete when faced with common challenge

22

Urges fight, flight, posture, or submission

23

non state societies have more war deaths than state societies

25
Q

Civilization Process

A

urbanization/civilization increase over time, then homicide rates decrease

26
Q

Masticatory-Functional Hypothesis

A

short wide skulls replaced longer, narrower skulls

softer diet, change in skulls, reduction in jaws (more malocclusion)

27
Q

Race-based Replacement

A

short-headed “race” invaded and replaced long headed “race”

28
Q

Effects of leisure time

A

Modern hunter gatherers have more leisure time, less stress on bones, leads to agriculture, cross sections are more even, rather than stronger in one direction

29
Q

Osteoarthritis

A

degenerative changes in joints where bones articulate, involving degeneration of cartilage and pathological growth of bone tissue-mechanical stress from excess physical activity
