"This 300,000-year-old skull may be from an African" Topic

… ‘ghost' population.

"A mysterious but well-preserved hominid skull found nearly a century ago comes from a population that lived in Africa around 300,000 years ago, as the earliest Homo sapiens were evolving, a new study finds.

This discovery indicates that a separate Homo population, perhaps a species some researchers call H. heidelbergensis (SN: 6/22/19), inhabited Africa at the same time as both H. sapiens and a recently discovered population dubbed H. naledi (SN: 6/10/17), say geochronologist Rainer Grün and his colleagues. African H. heidelbergensis could have been a recently reported "ghost population" (SN: 3/14/20) that interbred with ancient H. sapiens and passed a small amount of DNA to present-day West Africans, the researchers suggest April 1 in Nature…"

Hybridisation within the Human species is the new 'hot' topic, made possible with DNA science.

I believe there's an indication that H. Sapiens not only has Neanderthal & Denisovan admixtures but hints of a third, yet undiscovered, species.

I was under the impression that at least part of the definition of "species" was that hybridisation resulted in infertile offspring.

Does this make all the different human types members of the same species ?

And how can you tell the difference between admixtures due to hybridisation and genes from some common ancestor

Good questions….
