Description

Lillith C Zijmers leads a 2026 analysis of how much additive genetic variation, the raw material for evolution, differs between species. The team gathered thousands of published estimates of heritability and evolvability, a scaled measure of genetic variation, covering more than two hundred multicellular species of plants and animals.

Evolvability varied a great deal between species, and much of that spread followed family relationships. Plants showed substantially higher evolvability than animals. Heritability also varied, but less sharply, and plants were not exceptional there. Tests of mutation rate, population size, genome size, and other candidate drivers found little firm evidence, though the authors note their power to detect such links was limited.
