Evolutionary Theory Does Not Justify Greed
Human nature as it now exists was formed in accord with the laws of evolution under conditions pertaining well before recorded human history. Fossils discovered in Ethiopia and Kenya now date human ancestors back at least 5 or 6 million years. Distinctly human species arose in Africa at least 2 million years ago, while present evidence indicates that modern humans are only about 100,000 years old. Therefore the conditions relevant to which genetic mutations were advantageous and which were no... 1

Australopithecus afarensis' Hip Bone Indicates She Could ...
When Lucy’s hundreds of fragments were assembled, she turned out
to be a female of a new species, Australopithecus afarensis, dating back
3.2 million years. She was between 20 and 30 years old, 3.5feet tall,
weighing a scant 60 pounds, and possibly afflicted with arthritis. But
most important, she walked on two legs.
How can we tell? From the way that the femur (thighbone) connects to
the pelvis at one end and to the knee at its other. In a bipedally
walking primate like ourselves, the fem... 1 notes
notesThe bone tilts to bring the knees inward, like it does in humans, but not in chimps, who waddle because they are bow-legged.
