This allowed us to link molecular divergence with genetic connectivity in plants and animals. (A) Gene flow stops sooner between plant species than between animal species. (B) Genomic barriers emerge faster in plant genomes than in animals.

Using population genomic approaches, we measured (A) average genomic divergence and (B) the probability that each plant or animal pair corresponds to: (2) two populations of the same species, (3) a complex of semi-isolated species, or (4) two fully isolated species

In this study, we analyzed the demographic histories of 280 plant pairs and 61 animal pairs using genomic data describing both intraspecific polymorphism and interspecific divergence

Hybridization and introgression are major evolutionary processes. Since the 1940s, the prevailing view has been that they shape plants far more than animals. In our new study (www.science.org/doi/10.1126/...
), we find the opposite: animals exchange genes more, and for longer, than plants
