Apparently he spoke in an atheist convention calling Star Trek an "Atheist mythology"
Which I'm ok with but it seems to me that Star Trek's version of evolution is a goal oriented evolution where encoded in our gene, we will evolved in a specific direction that can't be changed (aka not affected by the environment) as shown in Threshold.
This is even supported by previous episode in Star Trek where in TNG "The Chase' where it was shown that bunch of aliens "seeded" the entire galaxy and programmed the "evolution" of species to become humanoid which explains why most of the aliens look like humans with rubber foreheads.
It seems like The Chase's aliens had a wicked sense of humour and also programmed all those humanoids to eventually "evolved' into salamanders.
Trek's evolution is like a weird version of intelligent design where god like aliens programmed our development in our DNA.
