Evolution Notes:
· Pit of bones is in Europe
o .5 million years
o scientists found remains of 30 skeleton of homo heidelbergensis?
o Pink quartz found w/ remains: important b/c hand axe, musve been brought from far away,
FIRST SYMBOL OF OFFERING EVER FOUND
· Homo neanderthalensis on earth:
o Scientists found first fossil of them in Muir Valley of Belgium (jawbone of young boy 1000
years old)
§ Almost complete mouth, trying to reconstruct
§ Scientists think he was 11-12 years old when he died but he was only 8 years old (grew up
faster, less time for brain to develop)
§ Brain:
· Front: human like (brocas area & frontal lobe)
· Parietal & temporal lobes: smaller (language, memory): sign of limited thinking
§ Bones showed diet: almost exclusively meat even though they had options
· Carnivores: more like wolves than humans
· Homo neanderthalensis:
o Knives or thrusting spears (must get close to prey to kill)
o Very few lived past 30
o Lasted for 400,000 years
· Homo sapiens:
o Originated 200,000 years ago
§ Used tools
o Great Rift Valley

Pit of bones is in europe: . 5 million years, scientists found remains of 30 skeleton of homo heidelbergensis, pink quartz found w/ remains: important b/c hand axe, musve been brought from far away, Homo neanderthalensis on earth: scientists found first fossil of them in muir valley of belgium (jawbone of young boy 1000 years old) Scientists think he was 11-12 years old when he died but he was only 8 years old (grew up faster, less time for brain to develop) Front: human like (brocas area & frontal lobe) Parietal & temporal lobes: smaller (language, memory): sign of limited thinking. Bones showed diet: almost exclusively meat even though they had options. Homo neanderthalensis: knives or thrusting spears (must get close to prey to kill, very few lived past 30, lasted for 400,000 years. Homo sapiens: originated 200,000 years ago. Used tools: great rift valley, almost went extinct 140,000 years ago b/c of mega droughts.
