1. Using Ch. 10 from your text only, name and describe (in your own words) four of the seven steps of bipedality.
1. An arch in the foot is one step of bipedalism. The arch works as a shock absorber from walking, running & jumping, whereas the flat arch of an ape, for example, is utilized more for grabbing or holding objects (Larsen, 2016).
2. Another sign of bipedalism is the difference in toes, most importantly, the big toe. In humans, the big toe provides support & balance. Apes use their big toes for walking and grabbing, treating the feet as a secondary set of pseudo hands (Larsen, 2016).
3. The human spine is shaped in a manner which provides greater stability and a better center of gravity than in quadrupeds.
4. Anthropologists have also linked another step of bipedalism to fossils by examining the pelvis. A pelvis with a short ilium and a broader pelvic bone, in general, are signs that a creature was bipedal (Larsen, 2016).…show more content… Using outside sources, describe the Piltdown Fossils. Where were they found? What was the significance of this discovery? After inquiry, what was discovered about the fossils? (be sure to cite your outside sources!!)
The Piltdown fossils, found in Piltdown, England during 1911 and 1912, were believed to be the missing link between apes and humans. These fossils contained part of the skull, a jawbone, and some teeth. Eventually, it was discovered that these remains were not what they had initially been made out to be, leaving other discoveries within the realm of human evolution to seem irrelevant until 1953 when the skillful hoax was finally reported ("Science Odyssey: People and Discoveries: Piltdown Man is revealed as fake,"
