Females supercharge sperm evolution in animals

Sperm size varies dramatically among different animal species. But why is sperm size so variable when they share the same job—to fertilize eggs? In a new article published in Nature Ecology and Evolution, researchers from ...

Darwin got sexual selection backward, research suggests

Charles Darwin was a careful scientist. In the middle of the 19th century, while he was collecting evidence for his theory that species evolve by natural selection, he noticed it didn't explain the fancy tails of male peacocks, ...

Heat spells doom for Aussie marsupials

When animals are hot, they eat less. This potentially fatal phenomenon has been largely overlooked in wild animals, explain researchers from The Australian National University (ANU) in a new article.
