Neanderthal - Australoid

Did you see similarities between neanderthals and Australoids, except of black skin??

Thay have similar mouths and fronts, and 80% of australoids have blonde hairs.

Can anybody explain these similarities?

Not so similar. Australoids supposedly descend from an admixture of the Javanese-type Homo Erectus and Homo Sapiens.

Well, this makes sense, because, in the scale of evolution Neanderthal is between Homo Erectus and Sapiens, even while Neanderthals were smart, but in the physical traits they were intermediate.

Well, I everytime wonder why we have not non-sapiens lineages, it is very misterious to me. Maybe there were bottlenecks around the world, but I don't know how it can happens, to have bottlenecks in all cases. The probability is very low.
