Biologists are closing in on a puzzle that seems to turn classic evolutionary logic inside out, yet may be so common that it ...
It may have fewer than many of the other sciences, but biology does have two dozen or so “rules”—broad generalizations about ...
Are bears getting soft on us? After centuries of living in close proximity with people, a population of brown bears has ...
“Expression tells us what cells do, but regulatory DNA tells us where they come from, how they develop, and which germ layer ...
One of the biggest quests in biology is understanding how every cell in an animal's body carries an identical genome yet ...
Researchers at the University of Tokyo have created an RNA molecule that can not just replicate, but “evolve” into a diverse range of more complex molecules. This find could plug a major gap in the ...
The DNA mutations that drive evolution are generally thought to be fairly random, but a new study suggests there’s some order to the chaos. Comparing the genomes of hundreds of plants grown in a lab, ...
Why does natural selection appear to happen slowly on long timescales and quickly on short ones? A multigenerational study of four lizard species addresses biology’s “paradox of stasis.” James Stroud ...
When the world slowed down during the COVID-19 pandemic, its effects extended beyond humans. A recent study found that it reshaped urban ecosystems to such an extent that certain city-dwelling birds ...
