Various scientific studies have examined the mechanics of human locomotion. It looks as though mankind was made with an extremely efficient walking "gear." Can evolution be legitimately credited with the unique human leg ingenuity that this efficiency requires, or does the evidence better fit a more intelligent source?

One of the leading arguments for human evolution from a shared common ancestor with apes is the "chromosome 2 fusion model." This hypothetical model proposes that the end-to-end fusion of two small ape-like chromosomes resulted in the human chromosome 2, which supposedly explains the difference in chromosome numbers between humans and great apes.¹ A

What does it mean when two different species have the same "break points" in a supposedly broken gene? Does it suggest that God created them with similar features, or does it show that the two species evolved from one ancestor? How one answers this question may depend more on prior beliefs than evidence, but new findings make the latter scenario increasingly difficult to maintain.

For years, museum displays have featured the small extinct ape Australopithecus afarensis. The first specimen, discovered in 1974 and nicknamed "Lucy," was presented as having clearly human eyes, feet, and posture. The feet and posture, however, can only be verified by relevant fossilized structures.

In fall 2009, the journal Science dedicated a special issue to Ardipithecus ramidus. Popularly known as "Ardi," the fossil was characterized by researchers Tim White and C. Owen Lovejoy as a replacement for Lucy as mankind's direct evolutionary ancestor.
