Study!
-UP packet due Monday
Important Things from the Notes
-Humans and
Chimps diverged from a common ancestor 5-7 million years ago.
-Instead of
humans being directly related to chimps we are more like cousins or siblings.
Kinds of Hominids
I.
Australopithecus-
Walked in African savanna.
Were extinct by 1.4 million years ago.
II.
Homo
habilis- (“handy man”)
East Africa . Enlarged
brain. Had stone tools
III.
Homo
erectus- extension to other continents. Ate larger portions of meat. Taller and
had larger brain capcity. African, Asian, European, Australian
IV.
Neanderthals
(descendant of H. erectus/early Homo sapien)-Brain slightly larger than ours,
skilled tool makers, burials, rituals, and abstract thought. “Caveman” Europe,
Middle East, Asia.
V.
Homo
sapiens-
A. Archaic Homo sapiens
B. Cro-magnon
C. Homo sapiens sapiens
What
happened to various Homo erectus descendants?
-
1. Multiregional hypothesis- Modern humans evolved at the exact
same rate and way in different parts of the world. Genetic similarity was
caused by interbreeding between neighboring populations
-
2. “Out of Africa” hypothesis
(replacement hypothesis)- Modern humans arose from a single group in Africa.
Neanderthals and others outside humans were evolutionary dead ends. Eventually
moved out of Africa. Genetic evidence mostly supports this.
Important features of humans
-Erect stance
-Enlargement of brain
-Culture
-3 major culture changes: Nomads, Agriculture, Industrial
That’s all!
Good luck on Monday!
