The racists love to fondle and abuse miniscule sciency-lookin' factoids into their spew. There's evidence that H. Erectus was the first out-of-Africa human diaspora, with a following wave of early H. Sapiens ages later. Neanderthal's were a climatic era niche species that did not wander far afield because they were weird like that, and probably because they did not like change. They made virtually the exact same style of tools for hundreds of thousands of years with no advancement. I'd rather not talk about that side of my family. They embarrass me. Yet, I can see why the fringe-y racist uber fuckwits lay claim to Neanderthal blood with pride; all that sameness, clannishness, xenophobia, non-existant art, spears-spears-and-more-spears, over and over, just like their great-great-to-the-6th-power grandkids.
