Your approach is far too black-and-white. MR doesn't contradict natural
selection. It rounds it out. It restores evolutionary theory to its
Darwinian moors by incorporating the inheritance of acquired traits. You
should be aware that Darwin considered the capacity of organisms to shape
their evolutionary future as being essential to evolutionary theory. As far
as Darwin was concerned, there is no theory of evolution if the behavior of
organisms isn't its driving force. He would certainly have been appalled
at what has been put forth in his name in this century.
MR isn't going to save a species when the material basis of its existence,
genetic or environmental, is no longer present.
