Prokaryotic beneficial mutations can propagate quickly and across species lines

by idebunkforme

In a new paper published in Science, prokaryotes can propagate beneficial mutations from recombination even in cousin populations. This may further impact the ability to define “species” in asexually-reproducing organisms, as distinct bacteria could share most all of their genes. How taxonomy will work for bacteria in the future, if this study is any indication, could rework definitions that perform well for sexually-reproducing eukaryotes.
