This certainly holds true for Europe, where the perceived differences between the earlier Neanderthal populations and later “modern” H. There are many sites which are attributed to what are called “early modern humans” are not always particularly older than “fully” modern humans, nor later than Neanderthal sites.As discoveries have continued over the last century Neanderthals are now clearly associated with Upper Paleolithic sites, and “modern” humans are no longer an Upper Paleolithic history of the interpretation of the European fossil record is marred by the fact that early attempts to demonstrate continuity by researchers such as A. Schwalbe were troubled by misdated specimens and faulty reconstructions, while early attempts to demonstrate replacement were based on the Piltdown hoax and the misdated Galley Hill material.Some see direct competition and extermination of the native populations, some see passive replacement due to better adaptive strategies, and some see genetic admixture with the preponderance of genetic material coming from the incoming human populations, eventually replacing and assimilating them into the greater collective.In this view there is a specific speciation event that occurred which led to the origin of There are various models which embody combinations of these ideas, different “strict” interpretations of the two theories, etc. Whereas in the previous species have been introduced with historical background and a discussion of the early, most important finds, and the individuals responsible for the species designation, this introduction will focus on some of the theory implicit in the discussion of the origin and spread of Most researchers currently accept the statement that “modern” humans can be considered to date to approximately 200–250 kyr.Others (such as Milford Wolpoff), take the view that our species extends as far as approximately 2.0 myr, subsuming .This has led to some fairly severe strife within the paleoanthropological community, with potshots often taken unfairly at rival theories and rival theoreticians.

In fact, these two specimens are significantly atypical.

At approximately 200 kya there was a second migration of hominids out of Africa.

This time it was fully modern , which proceeded to replace whatever populations that then occupied Asia and Europe.

Adherents to this model look at early material and try to trace continuity in morphology from those early populations to later populations in the same geographic area.

In this model, there are paralleled changes in all penecontemporary populations, with enough genetic migration to maintain close species bonds, while still allowing the suite of racial features we see today.) did not contribute a significant amount of genetic material to later populations that led to modern humans (some claim no genetic ancestry to these groups and their descendants at all, a “strict” replacement model).
