1 The extinction vortex, is genetic variation related to extinction?; 2 How to measure genetic variation; 3 Inbreeding, geographic subdivision, and gene flow; 4 Genetic diversity in changing ...

Heritability isn't a fixed biological property but a measure that depends entirely on the population and circumstances you're ...

New research suggests genetics account for up to 56% of lifespan variation, a significant increase from previous estimates. This shift is attributed to changing mortality patterns, with fewer deaths ...

The present theory offers a unified solution to three closely related evolutionary problems. (1) Why does an evolving population explore only a small fraction of the accessible pathways in genotype ...

Even a single gene, reshuffled or regulated in new ways, can fuel repeated bursts of evolutionary innovation, according to a recent study of wheatear birds. A study was recently published in the ...

Researchers have significantly expanded the catalogue of known human genetic variation. The resulting datasets, shared in two back-to-back publications in the journal Nature, constitute what may be ...
