Scientists comparing the fetal development of the eye of the owl monkey with that of the capuchin monkey have observed that only a minor difference in the timing of cell proliferation can explain the multiple anatomical differences in the two kinds of eyes. The findings help researchers understand how a structure as complex as the eye could change gradually through evolution, yet remain functional. The findings also offer a lesson in how seemingly simple genetic changes in the brain and nervous system could produce the multiple evolutionary changes seen in more advanced brains, without compromising function........
