A 2019 reanalysis of 210,000-year-old skull fragments from the Greek Apidima Cave assumed to have belonged to a Neanderthal concluded that they belonged to a modern human, and a Neanderthal skull dating to 170,000 years ago from the cave indicates H. sapiens were replaced by Neanderthals until returning about 40,000 years ago.

The new research estimates an average date for Neanderthal-Homo sapiens interbreeding of about 47,000 years ago, compared to previous estimates that ranged from 54,000 to 41,000 years ago.
However, genetic evidence from the Sima de los Huesos fossils published in 2016 seems to suggest that H. heidelbergensis in its entirety should be included in the Neanderthal lineage, as "pre-Neanderthal" or "early Neanderthal", while the divergence time between the Neanderthal and modern lineages has been pushed back to before the emergence of ...
Neanderthals may have been at a demographic disadvantage due to a lower fertility rate, a higher infant mortality rate, or a combination of the two. [59] [54] In a sample of 206 Neanderthals, based on the abundance of young and mature adults in comparison to other age demographics, about 80% of them above the age of 20 died before reaching 40.
Over this 7,000-year time frame, early humans encountered Neanderthals, had sex and gave birth to children on a fairly regular basis. The height of the activity was 47,000 years ago, the study ...
Using the percent distance from human–chimpanzee last common ancestor, Denisovans/Neanderthals split from modern humans about 804,000 years ago, and from each other 640,000 years ago. [25] Using a mutation rate of 1 × 10 −9 or 0.5 × 10 −9 per base pair (bp) per year, the Neanderthal/Denisovan split occurred around either 236–190,000 ...
Neanderthals were a species of early human that evolved from the same common ancestor as Homo sapiens — modern humans — between 700,000 and 300,000 years ago, according to the Smithsonian. We ...
The earliest evidence for life on Earth includes: 3.8 billion-year-old biogenic hematite in a banded iron formation of the Nuvvuagittuq Greenstone Belt in Canada; [30] graphite in 3.7 billion-year-old metasedimentary rocks in western Greenland; [31] and microbial mat fossils in 3.48 billion-year-old sandstone in Western Australia.
