Answers Quote by Roger Lewin
“The central question of the Chicago conference was whether the mechanisms underlying microevolution can be extrapolated to explain the phenomena of macroevolution. At the risk of doing violence to the positions of some of the people at the meeting, the answer can be given as a clear No.”

A Different Perspective
Complex macroevolutionary patterns may involve additional mechanisms not seen in microevolution.
