Document Summary
Our dna is more similar to chimpanzees vs gorilla-chimpanzee comparision. Molecular systematics indicates that both humans & chimp have evolved due to divergence. What we know about human health can be applied to other organisms of the same species that have a common ancestry. Similary, studies on animals can be applied to humans. Sense of histry- in humans its represents as spirituality. Humans are primates: forward facing eyes, extensive parental care, unique behaviour, hands with nails, not claws. We are the one only ones that are bipedal. 1) bipedal is more conservative, 2) less sun exposure when bipedal. Hands allow us to carry things long distances. The mouth is no longer used for storage. This may have causes the evolution of speech and advancements of mouth. Increase brain size is the result of many factors.
