Scientists have identified an unexpected source of genetic variation in human sperm that occurs earlier in sperm development than previously thought. Published in Nature, researchers at the Wellcome ...

A 30-year-long study of a small population of marine snail shows how evolution can adapt to environmental changes quite rapidly. This study revealed how a specific ecotype of the snail changed its ...

Natural selection has long been considered the driving force behind human evolution. But a landmark study of 87 fossil skulls spanning the past two million years suggests the story is far more complex ...

A genomic study of human and selected nonhuman primate centromeres has revealed their unimaginable diversity and speed of evolutionary change. In cell genetics, a centromere is the spot where two ...

Adaptive evolution arises when heritable genetic variation confers a fitness advantage under changing environmental or ecological conditions. Central mechanisms include the generation of variation ...

Humans are still evolving, and Tatum Simonson, PhD, founder and co-director of the Center for Physiological Genomics of Low Oxygen at University of California School of Medicine, plans to use ...

A genomic study of human and selected nonhuman primate centromeres has revealed their unimaginable diversity and speed of evolutionary change. Although centromeres are vital to proper cell replication ...
