A study concluded only 1.5–7% of "regions" of the modern human genome to be specific to modern humans. These regions have neither been altered by archaic hominin DNA due to admixture (only a small portion of archaic DNA is inherited per individual but a large portion is inherited across populations overall) nor are shared with Neanderthals or ...
All modern human groups outside Africa have 1–4% or (according to more recent research) about 1.5–2.6% Neanderthal alleles in their genome, [91] and some Melanesians have an additional 4–6% of Denisovan alleles. These new results do not contradict the "out of Africa" model, except in its strictest interpretation, although they make the ...
Based on the assumption of a constant molecular clock, the study predicts the gene loss occurred relatively recently in human evolution—less than 240 000 years ago, but both the Vindija Neandertal and the high-coverage Denisovan sequence contain the same premature stop codons as modern humans and hence dating should be greater than 750 000 ...
Jeffrey Charles Hardy claims human evolution is paused due to our dominance over nature and urges us to shape the next stage toward peace and sustainability. A Futurist Says Humanity Is Evolving ...
Experts estimate that modern humans first appeared between 42,653 and 42,269 years ago. Therefore, the authors conclude this suggests the two species of humans co-existed in these regions for ...
The finding that "Mitochondrial Eve" was relatively recent and African seemed to give the upper hand to the proponents of the Out of Africa hypothesis.But in 2002, Alan Templeton published a genetic analysis involving other loci in the genome as well, and this showed that some variants that are present in modern populations existed already in Asia hundreds of thousands of years ago.

Compared to the modern and extinct great apes, A. afarensis had reduced canines and molars, although they were still relatively larger than in modern humans. A. afarensis also has a relatively small brain size (380–430 cm 3) and a prognathic (anterior-projecting) face.
Homo sapiens (red) Expansion of early modern humans from Africa through the Near East. In paleoanthropology, the recent African origin of modern humans or the "Out of Africa" theory (OOA) [a] is the most widely accepted [1] [2] [3] model of the geographic origin and early migration of anatomically modern humans (Homo sapiens).
