alt Hacker NewsThat's because when something becomes a new species is a surprisingly difficult and contentious debate in biology.
That's simply due to the nature of evolution. It's nearly impossible to look at one past generation of chicken to the next to figure out when the ancestor was no longer a chicken. Yet, go back far enough and you'll find T-Rexes in the mix.
Every generation is a new missing link. It's an extremely fuzzy process.

This is because "species" is a taxonomical category that we invented, but that does not actually map cleanly to reality.

Afaik, T-Rex was never a direct ancestor of modern birds, including chicken. T-Rex and birds are theropod dinosaurs, but it was a very large and diverse group of animals.
