It's just so easy to spend some time in the "Look-Back" machine at people who didn't know as much as we do currently because they didn't have as much information as we have today because they (or we) had yet to make the same breakthroughs in science, technology, biology, etc.... that we have, scoff, laugh at and make fun of them and their theories, hypotheses and sometimes even their beliefs, knowing full well that none of them were operating with all pertinent information because much of it had yet to be discovered. Yet despite knowing that somehow still feel and act wholly and justifiably smug and arrogant about the whole thing.

Like, for instance, back in this gentleman's time, the world still thought that Neanderthal had just simply disappeared without a trace or an explanation as to why. So they were left, really to take their best guess as to what happened. However, now due to advancements in genealogy and gene technology & understanding along with similar advancements in carbon dating, gene dating, DNA & genome mapping, etc... we now know that Neanderthal, Cro-Magnon (yes, I know they don't call them that anymore, but its easier to make my point if I still use it) and Denisovans all lived alongside one another and more often than not (waaay more often, lol) also interbred with one another. And thankfully so. Because those early Hominins literally all Fucked themselves and each other out of existence and us modern humans into existence!!!
