Hey everyone, let’s put out a press release, and another one, and one more:
A new, complete 'tree of life' tracing the history of mammals on Earth shows that they did not diversify as a result of the death of the dinosaurs. It contradicts the previously accepted theory that the Mass Extinction Event that wiped out the dinosaurs 65 million years ago prompted the rapid rise of the mammals we see on the earth today.
Research shows that after the mass exteinxtion certain mammals did experience a rapid period of diversification and evolution. However, most of these groups have since either died out completely or declined in diversity.
The researchers believe that our 'ancestors', and those of all other mammals on earth now, began to radiate around the time of a sudden increase in the temperature of the planet – ten million years after the death of the dinosaurs.

The tendonitis has improved so I'll be slowing bring the blog back up to speed, although I'll probably not hit 100% of what I was doing before.
