Scientists have identified an unexpected source of genetic variation in human sperm that occurs earlier in sperm development ...

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 ...

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 ...

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 ...

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

A groundbreaking DNA study has unveiled a hidden chapter in human evolution, revealing that all modern humans evolved from two ancient and distinct groups. This research, published in March 2025, ...

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 ...
