Dinosaurs and Their Ancestors
I found it interesting to read that it now appears that certain species of dinosaurs roamed the Earth at the same time as their ancestral species.
Now, researchers report in the journal Science they have evidence from northern New Mexico that dinosaurs and their precursor species coexisted for tens of millions of years.
This is an interesting demonstration of how evolution works. It’s not always a new species replacing an old one. Sometimes the old one is doing well enough to stick around, despite the divergence in its population to the point that some are an entirely different species.
It makes sense to me. A species does not just evolve into one other species. If it did, we wouldn’t have the sheer range of life around now. It can evolve into multiple species, depending on the conditions each face, and yet the original species may still be viable.
