1. Human evolution

2. Hominid Evolution Common ancestor 5-7 mya Chimps
Remained in trees
Australopithecus afarensis
“Lucy” 3-4 mya
Bipedal, left trees, ~3 feet tall
Lived off land, walked around

3. Lucy is the most complete fossilized remains of the family Hominidae.

4. Lucy was discovered by a paleontologist from Cleveland.
Her original remains & recreation of what she may have looked like are now housed in the Cleveland Museum of Natural History
There is a substantial exhibit of Human evolution in the museum
The picture of what Lucy’s recreation that follows was taken in the Cleveland museum in April,2014

5. Cleveland Museum of Natural History Exhibit, April, 2014
Notice that Lucy is looking up at the visitors. She is quite short compared to modern humans. Her knees lock (evolutionary development) & she walks upright

7. Homo habilis

10. Common Ancestor & Cladistics
Cladistics is the mapping of the relationships of organisms
Common ancestor is at the base of the tree.
The organism from which all life originated.
