Human Evolution II

Paranthropus aethiopicus The “Black Skull” West Turkana, Kenya, 2.5mya Brain size = 410cc

Paranthropus robustus Swartkrans, South Africa 1mya Brain size = 500cc

Olduvai Gorge, Tanzania 2.1-1.7mya Brain size = 500cc Paranthropus boisei OH5 “Zinj” Olduvai Gorge, Tanzania 2.1-1.7mya Brain size = 500cc

Homo habilis from South Africa and Olduvai Gorge Brain = 600cc

Homo habilis KNM-ER 1813 Koobi Fora, Kenya, 1.8-1.6mya Brain = 510cc

Kenyanthropus platyops and KNM-ER 1470, Homo rudolfensis

Dmanisi, Georgia - 1.75mya

Science, 5 July 2002

The Nariokotome Boy (“Turkana Boy”) WT15000 1 The Nariokotome Boy (“Turkana Boy”) WT15000 1.6mya Adult brain size would have been 909cc

Achievements of H. erectus Increased body size and more efficient bipedalism. Embraced culture as a strategy of adaptation. Brain was reshaped and increased in size to within H. sapiens range. Efficient scavenger and hunter with greater dependence on meat. Evolution of the human nose!

Homo erectus from Java Brain size 813-1,059cc Sangiran, 1.6mya

Homo erectus from Java

Zhoukoudian Homo erectus

Advantages of Use of Fire Warmth. Cooking. Fire-hardening wood. Aiding in the production of stone tools. Chasing predators from caves. Illuminating caves and extending usable light into the night. Advantages of Use of Fire
