it's a curious fact of nature that
severe asteroid impacts on earth can
devastate the ecosystem leaving most
life extinct countless tons of Earth's
crust get cast high into the atmosphere
while soot from widespread fires cloaks
the planet knocking out the base of the
food chain and sending a wave of
extinction across the Tree of Life
sounds bad
it is but the loss of so much life also
prise open fresh niches that allow new
forms of life to thrive for the famous
KT impact 65 million years ago the one
that ended the reign of the dinosaurs as
much as two-thirds of all species were
wiped out but among those creatures that
did survive we find our mammal ancestors
a mere twig in the tree of life but
without dinosaurs to dine upon them
these early mammals could evolve into
something more ambitious like modern-day
primates like people asteroids you can't
live with them and you can't live
without it and that is the cosmic
perspective
