Evolution Could Soon Protect Humans from Alcoholism - Newsweek


Newsweek
Humans may be evolving a genetic variant that would make them physically unable to consume large amounts of alcohol, new research suggests. If this gene is able to take hold on the global population, it could one day help reduce alcoholism and alcohol ...

Land plants arose earlier than thought—and may have had a bigger impact on the evolution of animals - Science Magazine


Science Magazine
Some scientists have tried to use plant genetic data as "molecular clocks"—knowing a typical mutation rate, they can estimate how long ago various species split based upon their differences in DNA-to figure out their evolutionary history. But they ...

New software helps detect adaptive genetic mutations - Medical Xpress


Medical Xpress
Using a new machine learning approach, researchers at Brown's Center for Computational Molecular Biology found adaptive mutations in metabolic genes in a group of African hunter-gatherers. One mutation the software found is closely linked …more ...
