Neanderthals (/ n i ˈ æ n d ər ˌ t ɑː l, n eɪ-,-ˌ θ ɑː l / nee-AN-də(r)-TAHL, nay-, - THAHL; [7] Homo neanderthalensis or H. sapiens neanderthalensis) are an extinct group of archaic humans (generally regarded as a distinct species, though some regard it as a subspecies of Homo sapiens) who lived in Eurasia until about 40,000 ...
Neanderthals became extinct around 40,000 years ago. Hypotheses on the causes of the extinction include violence, transmission of diseases from modern humans which Neanderthals had no immunity to, competitive replacement, extinction by interbreeding with early modern human populations, natural catastrophes, climate change and inbreeding depression.
Homo antecessor may be a common ancestor of humans and Neanderthals. [ 40 ] [ 41 ] At present estimate, humans have approximately 20,000–25,000 genes and share 99% of their DNA with the now extinct Neanderthal [ 42 ] and 95–99% of their DNA with their closest living evolutionary relative, the chimpanzees .
The research for the first time pinpoints a short period 48,000 years ago when Homo sapiens interbred with Neanderthals after leaving Africa, after which they went on to expand into the wider world.
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 ...
The study found that humans left Africa, encountered and interbred with Neanderthals in three waves: One about 200,000 to 250,000 years ago, not long after the very first Homo sapiens fossils ...
[44]: 93–96 This was a continuation of Carl Linnaeus' 1735 Systema Naturae, where he invented the modern classification system, in doing so classifying humans as Homo sapiens with several putative subspecies classifications for different races based on racist behavioural definitions (in accord with historical race concepts): "H. s. europaeus ...
Then by excavating layers covering about 30,000 years, archaeologists compared the data with other sites in the same area dating back to a more recent period when Homo sapiens were confirmed in ...
