Lamarck wins Evolution caucus, this just in!

Vindicated

A slightly technical article arguing that a broader evolutionary synthesis is needed, one that unites Neo-Darwinism with something the author calls Neo-Lamarckianism. The article argues that the rate of genetic mutation is too slow for evolution to happen - an old creationist argument, which all anti-creationist polemicists said was simply WRONG, period. Except that it wasn´t. 

The solution is something the author calls "environmentally induced epigenetic transgenerational inheritence". No less! I don´t doubt that this is true, but if the environment directly impacts evolution, doesn´t this mean that the biosphere is more integrated than we previously imagined? 

Perhaps it´s the biosphere (let´s call her Gaia) that evolves, rather than the individual organisms, which are just cells in the larger whole (this meant in a non-trivial fashion). Of course, the really yuge paradigm shift would be to find direction in evolution, but that´s probably still off with another 100 years... 

We need both Darwin and Lamarck
