Not a particularly intelligent contribution, but I recall several sci-fi
stories, and I believe I saw some mail-order book once that was serious,
that suggest that the dinosaurs were not wiped out by lava flows on the
deccan flats, or the asteroid strike in he gulf of Mexico, but by a nuclear
war/accident occuring amongst an advanced saurian race (actually, star trek
voyager suggested they left the planet and travelled across the galaxy to
set up hom elsewhere...).
Dinosaurs had many times as long as we've had to evolve big brains etc., but
one serious point about evolution is that it is not progressive is it? If
an organism is adapted to its environment, and that environment remains
largely uniform for long periods of time, there's no pressure to evolve into
'higher' organisms. Or, perhaps its more correct to say that only a particular set of environmental pressures led to the circumstances whereby a large brained primate succeeded.
