"You are not really a scientist. You are a biologist"

PZ Myers responds to this over at Pharyngula.He notes that sci-fi programs have physicists as advisors rather than biologists - and the biology in the shows is almost universally awful (Vulcans producing viable offspring with humans? They're not just different species but they are in a whole different domain! (Then again Star Trek does have an xeno-IDer so...)). Evolution happening to individuals, rather than populations, aliens who couldn't possibly have evolved (eg., Alien).Anyway, it generated a lot of discussion, so anyone interested in the issue might gain some interesting insights by reading it.
