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

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 ...

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 ...

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 ...

New research explores how superspreading affects pathogen evolution, revealing its role in shaping virulence and influencing ...

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 ...

Young chimpanzees are remarkably innovative, inventing tools and improving on ones that adults use—and this technical ...

The striking black-and-white patterns of the wheatear are shaped by a mosaic of genetic variations, influencing the bird's ...

A new study has shown that person-to-person variation in antibody immunity plays a key role in shaping which influenza (flu) strains dominate in a population. The work, published today as a Reviewed ...

As a Ph.D. student, I wanted to understand the evolution of individual differences in fruit fly behavior—the building blocks ...
