Learn how Neanderthals in Europe suffered a loss of genetic diversity during the Ice Age, causing a single lineage to take ...

By sequencing ancient DNA from the fetus, scientists revealed a severe genetic bottleneck that reshaped Neanderthal history ...

Cute but cantankerous, koalas are making a surprising recovery from a genetic bottleneck, with their once most-threatened ...

The extinction of the Neanderthals is one of the most intriguing mysteries in paleoanthropology, with researchers speculating everything from shifts in the climate to war with modern humans may have ...

A study incorporating fresh DNA data and archaeological evidence has revealed that the last Neanderthals in Europe experienced a massive population turnover. The research shows that late Neanderthals ...

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 ...

A new study published in Science is challenging long-held assumptions about how we measure genetic risk in endangered species. Researchers analyzed whole genomes from hundreds of koalas, finding that ...

When a plant or animal population is in serious decline, it can enter what's called a genetic bottleneck. Fewer individuals means less genetic diversity, which in turn makes it harder for the species ...

Long before modern humans appeared in Africa about 300,000 years ago, our ancestors faced a crisis that almost ended the lineage entirely. A groundbreaking study has revealed that between 930,000 and ...

Without interrupting their busy sleep schedule, Australia’s cute, if cantankerous, koalas have turned a truism of genetics on its head. In short, the proliferation of certain koala populations shows ...

The koala now ranks among a few species observed escaping a genetic bottleneck, in this case caused by overhunting that ...
