Evolutionary Biology: Concepts and Theories Explained
Discover the principles of evolutionary biology, covering natural selection, genetics, and the processes that drive species changes.
What was corrected
The article stated a 30-70% polyploidization figure, a molecular clock independent of generation time and population size, a single settled 60,000-70,000-year out-of-Africa expansion, that African populations carry essentially no Neanderthal DNA, and that Africans have ~100% Homo sapiens ancestry.
Qualified the polyploidy, molecular-clock, and out-of-Africa claims, and updated the Neanderthal-DNA figures for African populations per the 2020 findings.
Why this is better
The Neanderthal-DNA claim was outdated (superseded by 2020 research) and the others were textbook simplifications. Corrections use the current primary literature rather than adding unverified sources.
