Change in Bird Science

 So up until recently, the assumption about when dinosaurs into birds was about 70 million years ago.  But this may be much later than we thought. It seems that dinosaur-to-bird occurred well before this, and birds exploded afterward.

The interesting thing is the older assumption was that when the meteor hit the Earth, it cleared the path for birds to evolve and fly.


But newer information says that birds are much older than this. and their expansion into new biomes occurred well before the meteor hit. The mass extinction after the meteor did allow the birds to diversify even more, but was not the key event we once thought.

Interesting.

Some of my favorites
