I'm finishing up an interesting book titled
Evolution in Four Dimensions: Genetic, Epigenetic, Behavioral, and Symbolic Variation in the History of Life (
on Amazon.com)
by Eva Jablonka and Marion Lamb. And I just noticed that it now has
some reviews which it didn't before, which isn't surprising since it
just came out (I had it pre-ordered). Having glanced through them, I
recommend reading the reviews.
This book may be representative
of an important shift in evolutionary thought. While I enjoy Dawkins's
books, his simplifications leave me wanting more information and
somewhat frustrated. His books seem to ignore many other factors, which
this book actually goes into.
This takes a sort of middle of the
road approach, which usually draws my attention. For example, it never
claims that genes aren't important, or even not very important. To the
contrary, epigenetics seems to punctuate the importance of the genome
because their affects are only felt through genes. I also think that a
middle of the road path is the most sensible when we haven't done much
research and therefore don't have a lot of data to base conclusions on.
I
do disagree with John E. Mack (see the reviews on Amazon above) in that
I think it is good that they spent time on the behavioral and symbolic
affects on evolution. I do agree that they are pretty obvious, but this
just means that they don't get talked about, and sometimes it seems
they are forgotten. Any time there is inheritable variation natural
selection can (does?) occur. So let's not forget informational and
symbolic evolution, and also how they can affect genes via such things
as niche creation.
This seems to be a more integral approach to
evolution, and one that I think at least deserves more research to
either confirm, reject or modify.
