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 ...

Neanderthals may have been headed toward their demise much earlier than experts previously thought, new research suggests. In ...

Understanding the genetic and fitness consequences of anthropogenic bottlenecks is crucial for biodiversity conservation. However, studies of bottlenecked populations combining genomic approaches with ...

Their results showed an extreme direct loss of diversity due to the bottleneck event and found the overall fitness in the modern population had been impacted. Researchers found three categories of ...

Studies have found a pronounced decline in male effective population sizes worldwide around 3000–5000 years ago. This bottleneck was not observed for female effective population sizes, which continued ...

For more than a century, human origins have been told as a story of expansion, migration, and survival. But deep in that ...

What I got from the article is that a small population of 10 individuals may recover, and purge the very harmful mutations, but that their offspring will be stuck with a lot of mildly harmful ...

How a new method of inferring ancient population size revealed a severe bottleneck in the human population which almost wiped out the chance for humanity as we know it today. An unexplained gap in the ...
