My colleague and I have published a new study of cactus flowers which may help explain the conundrum. For more than a century ...

Sharks might not be a natural biological group, with most species potentially closer kin to rays than to an oddball group of sharks.

A study has traced thousands of conserved regulatory elements back 300 million years, revealing deep principles of plant genome evolution—a discovery that could pave the way for more precise ...

More than 2.3 million ancient genetic switches discovered in plants reveal how key growth controls endured 300 million years ...

A monkey descending a tree trunk often keeps its head up, moving almost like a cautious climber backing down a ladder. Squirrels and many other mammals, by contrast, tend to go headfirst. That ...

Wild scarlet monkeyflowers in California survived a historic drought by relying on a rapid evolution, marking the first time the process has been observed in the wild.

The three-dimensional shape of a protein can be used to resolve deep, ancient evolutionary relationships in the tree of life, according to a new study. It is the first time researchers use data from ...

A research team led by Profs. Zhu Min, Lu Jing, and Zhu You'an from the Institute of Vertebrate Paleontology and ...

A team of researchers looked at changes in tree richness across the lowland and montane forests of the Andes and Amazon over the last four decades. While their results didn’t show an overall shift in ...

The Amazon molly reproduces without sex. A genomic copy-and-paste trick called gene conversion may explain how it avoids evolutionary meltdown.

Researchers uncovered millions of ancient plant DNA switches—some older than flowering plants themselves—revealing a hidden evolutionary blueprint stretching back 400 million years. Most people have ...
