Until now, we only had fragments of these cousins. Now we have face. Studying our evolutionary development and our sister-species is one of my favorite aspects of archeology. We’re constantly developing new information.

Side note: look up the initial presentation of Homo naledi. The leading archeologist did a phenomenal talk a couple of years ago (I think in December). It was really an exciting presentation. But I’m also pretty nerdy.

And apologies, I did you a disservice by not replying to your single citation.

At the top of the definition:

however. Some examples include the ecological species concept, which describes a species as a group of organisms framed by the resources they depend on (in other words, their ecological niche), and the genetic species concept, which considers all organisms capable of inheriting traits from one another within a common gene pool and the amount of genetic difference between populations of that species.

The definition of genetic species are distinct due to more than just "can they successfully interbreed". It's more about their genetic drift and timeline.

Your own text extraction says things like "usually" and "almost always", because we have distinct examples of this happening over and over.

Like most of science and nature it's messy and categories are imperfect, but we use what we got to do the science we can.
