Divergent evolution is a pattern in which (according to mainstream evolutionary thought) two groups develop into distinct species due to differences in the demands driven by the environmental circumstances. Divergent evolution occurs (it is theorized) when a character is subject to different selective pressures or sufficient genetic drift. Thus the two characters gradually become increasingly different.
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[Citation Needed].
A recent article in Nature supposedly has demostrated the existence of this mechanism in a labratory setting.[1], as well as an article in Proceedings Biological Sciences [2]. Based on a review of bacterial genetics, biologists appear to be of the understanding that they have been studying divergant evolution for decades [3], with the first recorded instance being in the 19th century [4]
