A variety of animals have male-specific ornament traits and these ornaments are favored by female choice. Which male traits are preferred by females often varies among females. Genetic mechanisms that create and maintain variations in female preference has been one of the central questions in evolutionary ecology.

Researchers show that female nipples are more diverse in size than male nipples – going against assumptions from evolutionary biology.

Natural evolution has given us opposable thumbs, the ability to walk fully upright and brains that can reason. Now, scientists are poised to revolutionise fields from drug discovery to goods manufacturing by further harnessing evolution’s power in the laboratory.

Geophysical modeling of one of the world’s most important fossil sites reveals the history of the site where early humankind evolved.

Entomologist Gets First-ever Footage of the Lost Species in Primeval Jungles of Malaysia.

Nipponosaurus sachalinensis - a controversial hadrosaurid dinosaur whose fossilized skeleton was unearthed in southern Sakhalin in 1934 - is found to be a valid taxon and a juvenile that had not reached sexual maturity.

The complete skeleton of an 8-meter-long dinosaur has been unearthed from marine deposits dating back 72 million years at Japan’s northern island of Hokkaido, making it the largest dinosaur skeleton ever found in Japan, according to researchers.

Tohoku University researchers and their international collaborators have identified a possible genetic mechanism underlying the evolution of birds, according to a recently published study in Nature Communications.

Asexual reproduction increases when female cockroaches are housed as a group, not alone, enabling them to maintain a colony for at least three years without a male’s contribution.
