Big evolutionary changesPopular Science
•83% Informative
Noted public figures like David Attenborough have previously claimed that human evolution is over, but many researchers studying human evolution firmly disagree.
In biological terms, evolution is a change in gene variant (a.k.a. “allele”) frequency in a population over time.
Evolution is a process, not an outcome, and it doesn’t always happen linearly.
The type of evolution demonstrated in Mostafavi ’s research is purifying selection: The removal of harmful mutations from a population over time.
Another common form of not-so-flashy selection is stabilizing selection, where extremes remain rare.
