Direct dating human fossils

The suggestion dating was based on less accurate methods with possibilities of contamination and that a more reliable method has been found met with some skepticism among scientists specializing in this area of study and we can expect continued discussion.The article appeared in the s (PNAS) and here is the abstract of that article: Revised age of late Neanderthal occupation and the end of the Middle Paleolithic in the northern Caucasus "Advances in direct radiocarbon dating of Neanderthal and anatomically modern human (AMH) fossils and the development of archaeostratigraphic chronologies now allow refined regional models for Neanderthal–AMH coexistence.They were a cold adapted people and endured severe climate fluctuations, including several periods of increased glaciation throughout their existence.

Two researchers in a paper last week questioned these dates, arguing they had developed a more reliable means of establishing carbon-14 dates.

They posit Neanderthal extinction occurring around 39,000 years ago and raise the possibility the period of contact between entering from Africa could have been as brief as a few hundred years and was no greater than 6000 years instead of the previously accepted 15/20,000 years.

The most recent news making events are two: a challenge to the dates that have been assigned to Neanderthal remains closest to the time of their extinction; and a claim Neanderthals occupied a site in the Siberian far North, at much higher latitudes than previously thought possible.

First, let’s talk about the dating of arose as a separate species in Eurasia around 200,000 years ago and occupied a range stretching from Spain in the West to Central Asia in the East.

This is an informational tour in which students gain a basic understanding of geologic time, the evidence for events in Earth’s history, relative and absolute dating techniques, and the significance of the Geologic Time Scale.
