Dark Regions of the Genome May Drive the Evolution of New Species
12th September 2021
Genetic “dark matter” may drive the emergence of new species, new research finds.
These long, repeating stretches of the genome, called satellite DNA, may ultimately prevent incompatible animals from mating by scrambling the chromosomes in their hybrid babies, according to the study. And if animals from different populations can’t mate, they will diverge over time, leading to speciation.
‘Dark Regions of the Genome’ would be a great title for a move.
