A groundbreaking DNA study has unveiled a hidden chapter in human evolution, revealing that all modern humans evolved from ...

The present theory offers a unified solution to three closely related evolutionary problems. (1) Why does an evolving population explore only a small fraction of the accessible pathways in genotype ...

For a long time, evolutionary biologists have thought that the genetic mutations that drive the evolution of genes and ...

What is the nature of the genetic changes underlying phenotypic evolution? We have catalogued 1008 alleles described in the literature that cause phenotypic differences among animals, plants, and ...

A new Yale study provides a fuller picture of the genetic changes that shaped the evolution of the human brain, and how the process differed from the evolution of chimpanzees. For the study, published ...

Research from UChicago dissects how a single genetic switch helps butterflies mimic wing patterns of other species to protect ...

At the mercy of natural selection since the dawn of life, our ancestors adapted, mated and died, passing on tiny genetic mutations that eventually made humans what we are today. But evolution isn't ...

Researchers have identified a case of a sudden evolutionary change. In a new study, the scientists describe a population of columbines that have lost their petals, including the characteristic nectar ...
