Mr. Achenbach points out that the Ard lived 4.4 million years ago in East Africa.
According to him, She lived mostly in trees and she raised her offspring in trees. She sometimes came tot eh ground and walked upright.
Scientists think she could have been the transitional figure between old primates and more recent primates.She lived before Lucy, the 3.2 year old skeleton.
Scientists are still searching for our "lost common ancestor", a creature who is the ancestor of humans and chimpanzees. Many of hese creatures lived seven million years ago.
Ardi doesn't look like chimpanzees nor does she have their characteristics.
Chimpanzees probably developed separarte from Ard's group, the hominid.
The chimp and the gorilla have developed much more than the homind.
The hominid is primitive except for its' upright walkng adn its' brain development.
Owen Lovejoy, an anthropologist from Kent State University says that the Ards brought food to theri mates; something that was easier when a creature was good at upright walking.
Lovejoy heralds the male perntal involvement as a key point of human developemnt for survivla.
What do you amke of this?
Do you think we are distantly related to thee hominids?
