Koalas suffered a massive population decline that left them with dangerously low genetic diversity. However, new genomic research suggests their rapid rebound may be helping reverse some of that ...

According to a new genomic study of Australia’s koala populations, rapid demographic rebound may be able to restore once-lost genetic variation and drive recombination in ways that re-establish ...

Microbes often display cooperative behavior in which individual cells put in work and sacrifice resources to collectively benefit the group. But sometimes, "cheater" cells in the group may reap the ...

Human populations have waxed and waned over the millennia, with some cultures exploding and migrating to new areas or new continents, others dropping to such low numbers that their genetic diversity ...

Newfound evidence reveals that the upsurge of the exotic Nile perch in Lake Victoria had long-lasting effects on the genetic diversity of various local cichlid species, report scientists. Through ...
