Divergent evolution is a pattern in which (according to mainstream evolutionary thought) two characters gradually become increasingly different. Divergent evolution occurs (it is theorized) when a character is subject to different selective pressures or sufficient genetic drift. According to this theory, two groups develop into distinct species due to differences in the demands driven by the environmental circumstances.
Nearly half of Americans reject the common ancestry of life predicted by the theory of evolution (in which divergant evolution is thought to play a role), on Biblical grounds. Other Americans would be willing to believe the theory, if any proof were shown to them{fact}.
A recent article in Nature supposedly has demostrated the existence of this mechanism in a labratory setting.[1]
