A little Rishathra is always good for developing and blending genetic traits along with possibly creating a whole new race and/or species.

Lol, I read that book decades ago.

Sorry creationists but this thread is only for those of some knowledge/fact acceptance.

Creationism is a philosophical/theological perspective and not necessarily at all in conflict with the theories of evolution and its variations.

Most real Creationists (I.E. non Evangelicals) also believe in scientific biological evolution.

So why do you lead off with a slam on Creationists?

This is what's slowly been suggested/emerging the last few years. Human Evo was in part a web. Combos/re-combos of separately but parallel evolved hominin/species not a single line. The article says we all have app 2% Neanderthal DNA, but this does not apply to sub-Saharans.

That 2% is just an average. It varies more by ethnicity and geographic locale.
They estimated the proportion of Neanderthal-derived ancestry to be 1–4% of the Eurasian genome.[6] Prüfer et al. (2013) estimated the proportion to be 1.5–2.1% for non-Africans,[7] which was revised in 2017 to a higher 1.8–2.6% for non-Africans outside Oceania.[8] Lohse and Frantz (2014) infer a higher rate of 3.4–7.3% in Eurasia.[9] Prüfer et al. (2017) noted that East Asians carry more Neandertal DNA (2.3–2.6%) than Western Eurasians (1.8–2.4%).[8]

As anatomically modern Homo sapiens migrated out of Africa and around the rest of the world, they met and interbred with at least four different hominin species, according to new research from the University of Adelaide, Australia. Strikingly, of these hominins, only Neanderthals and Denisovans are currently known; the others remain unnamed and have only been detected as traces of DNA surviving in different modern populations.

Reconstruction of Homo floresiensis, an extinct hominin species that lived on the Indonesian island of Flores between 74,000 and 18,000 years ago.

“Each of us carry within ourselves the genetic traces of these past mixing events,” said Dr. João Teixeira, co-author of a paper published in the Proceedings of the National Academy of Sciences.

The article is not very tight with its numbers.

“For example, all present-day populations show about 2% of Neanderthal ancestry which means that Neanderthal mixing with the ancestors of modern humans occurred soon after they left Africa, probably around 50,000 to 55,000 years ago somewhere in the Middle East.”

But as the ancestors of modern humans traveled further east they met and mixed with at least four other groups of archaic humans.

“Island Southeast Asia was already a crowded place when what we call modern humans first reached the region just before 50,000 years ago,” Dr. Teixeira said.

“At least three other archaic human groups appear to have occupied the area, and the ancestors of modern humans mixed with them before the archaic humans became extinct.”​

So that would be five other archaic populations, Neanderthals plus four more.

And how do they know EH1 and EH2 were different hominid groups?

They have not found any sample of those species of humans so how do they know the deltas?

I've always thought there were more species at work than just homo sapiens sapiens and Neanderthals. On this whole planet, for only these two species to occur? It just never made much sense to me.

True, otherwise, how do you explain Oakland Raiders fans?

And how do they know EH1 and EH2 were different hominid groups?

By the differences between them.
