An engineered methylation pattern persisted for four generations of mice, demonstrating transgenerational epigenetic inheritance can occur in mammals.

Researchers use a CRISPR-Cas9 strategy to expand a desired trait from 50 percent of mouse pups to about 72 percent.

The McGill University paleontologist, who died from COVID-19, was known for using multidisciplinary methods to explore the origins of amphibians, birds, and mammals.

p53 is possibly the most important protein for maintaining cellular function. Losing it is synonymous with cancer.

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.

Novel genes, rather than regulatory DNA, underlie the evolution of morphological traits, according to research published today (Nov. 17) in __PLoS Biology__. The new linkurl:study;http://biology.plosjournals.org/perlserv/?request=get-document&doi=10.1371/journal.pbio.0060278 reports that genes found in simple freshwater animals -- but not in any other evolutionary lineage -- can drive changes in body plan, and stokes the flames of a long-standing debate among evolutionary developmental biologist

The University of St. Andrews behavioral ecologist studies the social structures and behaviors of whales and dolphins, recording and analyzing their acoustic communications.

Forced to respond to a climate that’s changing faster than it ever has, it remains unclear whether species’ adaptations can keep pace.

Noncoding RNAs are proving to be critical players in the evolution of brain anatomy and cognitive complexity.

Evidence from various sciences reveals that there are diverse ways of being male, female, or both. An anthropologist argues that embracing these truths will help humans flourish.
