btw this sounds interesting

What we have here, therefore, would be the earliest modern human found outside of Africa. But the phrase “modern human” can be misleading. When researchers use the phrase they mean that the jawbone belongs to a person whose features are more similar to ours than those of Neanderthals. It does not mean that we have discovered the proverbial Adam or anyone’s greatx-grandfather Joe. This particular outpost of Homo sapiens may have left Africa and died out. The only way to further test this would be to conduct DNA analysis, which is notoriously difficult to perform on fossils found in the Levant.

I wonder why is it so.
