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.
The “us and them” mentality that is a naturally human thought pattern has been made a fascinatingly black/white thought pattern in USA through all of their history, giving the need for a separate filter for most people when discovery of new “human species” is covered by US scientists or when reported by their news outlets, as the people and their news outlets are more superficial. As a European example of a difference, the most stereotypically Norwegian I know is a third generation Iraqi, but still being a 100% Norwegian.
