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 ...

Debunking some misconceptions about evolution - ZME Science


ZME Science
Evolution, by and large, has had center stage in shaping life as we know it. Everything that roots or runs, burrows or swims, grazes, pecks, or stalks has been steered by its hand. The idea has also spawned one of the most heated debates humans have ...

Evolution 101: Genetic Drift

Berkeley - United States

One of the basic mechanisms of evolution, genetic drift affects the genetic makeup of a population through an entirely random process.
