How Birds Survived the Asteroid

That is BirdNote.

The asteroid that struck the Yucatán 66 million years in the past wreaked worldwide ecological injury. It spelled the tip of most dinosaurs and different animals and destroyed the world’s forests.

But just a few bird-like dinosaur teams made it via. Scientists consider all these teams have been ground-dwellers. Most might fly, however being largely terrestrial was a key survival benefit within the absence of timber.

Which means that of the 11,000 species of birds that fly the skies, glide over the oceans, and flit among the many branches at this time, all descended from these historic ground-dwelling bird-like creatures.

The mass extinction totally modified life on earth. However as one world ended, one other unfolded. A substantial amount of the world’s current range of life emerged following the catastrophic occasions of 66 million years in the past. And many various teams of birds developed to reclaim a life within the timber. The birds round us at this time reside proof of nature’s resiliency.
