A new study theorizes that evolution ticks at different speeds, especially when a big group of organisms first appears.

The vaginal microbiome, a complex ecosystem inhabited by diverse microbial communities, plays a pivotal role in maintaining reproductive health and protecting against infections. Recent advancements ...

In five cases where vertebrates evolved monogamy, the same changes in gene expression occurred each time. In many non-monogamous species, females provide all or most of the offspring care. In ...

Modern humans descended from not one, but at least two ancestral populations that drifted apart and later reconnected, long before modern humans spread across the globe. Using advanced analysis based ...

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 ...

Researchers at the University of Maine are theorizing that human beings may be in the midst of a major evolutionary shift—driven not by genes, but by culture. "Human evolution seems to be changing ...

Evidence is mounting that epigenetic marks on DNA can influence future generations in a variety of ways. But how such phenomena might affect large-scale evolutionary processes is hotly debated. The ...

Researchers have discovered that infiltrating gliomas, a common brain and spinal cord tumor, are shaped by their genetic evolution and microenvironment, a finding that could lead to more targeted ...

CRISPR will get easier and easier to administer. What does that mean for the future of our species? In 2016, I attended a large meeting of journalists in Washington, DC. The keynote speaker was ...

Omer Gokcumen receives funding from National Science Foundation. But while slime is essential for all forms of complex life, its evolutionary origins have remained murky. Slime is made up of proteins ...
