Over 90 percent of mammals were wiped out by dino-killing asteroid

Quote:
Researchers at the Milner Centre for Evolution at the University of
Bath looked back over mammalian fossil reports and research that had
been published for about the last 100 years, specifically focusing on
the time frame on both sides of the meteor strike – about 68 million
years ago to 65.7 million years ago. They also concentrated on mammals
in North America.

Not only did they find that more mammals went extinct during this time
than the roughly 75 percent previously thought, but also that they
rebounded extremely quickly, with the number of species doubling those
found before the impact in just 300,000 years – a relatively short
time in evolutionary terms.

Maybe if another few per cent of mammals had survived, intelligence
might have evolved in a very different species.

It's first survival of accidents, then survival of the fittest.
