Gravity was weaker on Earth millions of years ago, making all life larger

http://news.yahoo.com/s/ap/20071121/ap_on_sc/biggest_bug_ever

The reason: Gravity depends on dark matter in the region of the
galaxy.

Dinos died out when things became heavier, Earth and the Sun moved
into
a region with less dark matter. Dark matter accelerates things by
shifting
mass. For hundreds of millions of years there was less gravity,
allowing
species to grow a lot larger. Everything was a lot larger hundreds of
millions of years ago, even trees. Then, things compressed by gravity
and large bodies couldn't survive the weight change. They needed to
re-evolve from the smaller species. All dinos taller than 5 feet dies
out.

We understand little about dark matter and skepticism is Bush-minded
and fascistoid in all things not big brother.
