A new study by investigators at Dana-Farber Cancer Institute and Harvard Medical School is providing one of the most detailed ...

Much of the phenotypic variation that is observed within and between species is the result of differences in gene regulation: specifically when, where and how much the genes are expressed. Given the ...

Many scientific discoveries are serendipitous—the result of chance. Seeing evolution in action in a cheese cave turned out to be exactly that for Benjamin Wolfe, associate professor of biology, and ...

Backman proposes that the combination of geometric cellular memory and gene mutations may have created a self-learning ... and our future? Imagine evolution not as adding more words to a dictionary ...

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 ...

Scientists in Helsinki studied nearly 400 dog families to see how new DNA mutations arise in puppies. They found that older parents, especially fathers, pass on more genetic changes. The research ...

A spider on the Canary Islands lost half its DNA but gained more genetic variety. Scientists say this changes how we ...

The arrival of agriculture coincided with a sharp rise in a gene variant that protected against the virus that causes winter ...

Yale scientists discovered that cavefish species independently evolved blindness and depigmentation as they adapted to dark cave environments, with some lineages dating back over 11 million years.

Tobacco smoking is linked to specific genetic mutations in MDS, affecting chromatin modification and RNA splicing pathways. A dose-response relationship exists, with higher smoking intensity ...
