Question 18

Features of erectine skull

Answer 18

• Robust
• Thick boned
• Oval shaped when viewed from back
• Angular vault
• Cranial suprastructures
  • Supraoribtal torus (brow ridge)
  • Occiptal torus (horizontal ridge)= pointed back
• No chin

Question 19

Features of human skull

Answer 19

• Torus slightly reduced
• Derived feature: higher, rounded skull, higher cranial vault
• Limited development of brow ridges
  o Outjutting of bones= chin (sapiens)

Question 20

Features of neanderthal skull

Answer 20

• Large muscular bodies (adapt to cold
• Large + long skulls
• More pronounced Ridges (supraoribtal torus)
• Occipital bun (dorsal end of skull)

Question 21

Features of neanderthal skull compared to sapiens

Answer 21

• Large brain case
• Sloped vault
o Humans different= have forehead (upward vault)
• No chins
• Large front teeth
• Bony structure around nose= more surface area for soft tissue (larger nose)

Question 22

why did neanders have larger nose than sapiens

Answer 22

o Adaptive trait for cold

• Air warmed before in lungs

Question 23

australopithecines climate changes

Answer 23

• warming and drying > forest to savannah woodland
  Explanations for bipedalism / origin
  2.5-1.5mya

Question 24

erectin climate changes

Answer 24

1.5-0.5
- Rapidly cooling climate
- ice sheets & land bridges; more of ocean ways are in ice sheets
o changes in vegetation
- Cooling selects for increase robust body size
- decrease in hominin diversity

Question 25

12 000> climate changes + social results

Answer 25

- At 12 000: stable climate Lifestyle changes= Agriculture origins (manipulating environment) > not aus   Australia: Homo sapiens 50 kya • Glacial melting prevented migration back suggest built sea crafts there
