In _How the Leopard Changed its Spots_, Brian Goodwin quotes Mayr
as saying:
(There is)"no clear evidence...for the gradual emergence of
any evolutionary novelty" -- Mayr quoted by Goodwin
unfortunately without giving a reference, not unusual for a popular
level book. Would anyone happen to know where Mayr says this?
Goodwin disagrees with Mayr [in Denton's quote] saying that microevolution
is guided by natural selection whereas macroevolution [origin of novelties]
occurs by principles of self-organization and does not require natural
selection.
Actually there are a lot of interesting and controversial things in
Goodwins book. For example, while not quite disowning Darwin, he
suggests that Darwin ruined biology by changing it from a hard science
to a historical science. Has anyone read this book?
