Vertebrate morphology exhibits remarkable diversity, reflecting a complex interplay of developmental processes, genetic regulation and environmental pressures. This variation arises from a combination ...

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 ...

G. Ledyard Stebbins (1906-2000)- an appreciation / Peter H. Raven -- Solution to Darwin's dilemma: discovery of the missing Precambrian record of life / J. William Schopf -- The chimeric eukaryote: ...

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 ...

The Origins Science Scholars Series will continue with a presentation by Cynthia Beall, Distinguished University Professor and the Sarah Idell Pyle Professor of Anthropology, titled “Tracing Evolution ...

Believe it or not, evolution isn’t blind or random chance. It is the natural result of having an advantage, even if it is very slight, that makes the difference between dying young or living to ...

In the October issue of The American Journal of Human Genetics, researchers present evidence that human evolution has led to a decrease in the prevalence of certain genetic variations that are ...

The concept of phenotypic trade-offs is a central element in evolutionary theory. In general, phenotypic models assume a fixed trade-off function, whereas quantitative genetic theory predicts that the ...

Most research in human genetics has historically focused on people of European ancestries—a long-standing bias that may limit the accuracy of scientific predictions for people from other populations.

This "cryptic color variation" is widespread in nature, but scientists have long debated how it persists across long periods of evolutionary time and what role it plays in evolution. The NYUAD team, ...
