How new bird species arise

Much of a centuries-old debate over where and how new bird species form has now been resolved. Researchers at the University of Copenhagen have provided evidence that birds in mountainous areas—where the vast majority of ...

Researchers create largest ever human family tree

Researchers from the University of Oxford's Big Data Institute have taken a major step towards mapping the entirety of genetic relationships among humans: a single genealogy that traces the ancestry of all of us. The study ...

Genomic effects of inbreeding on Scandinavian wolves

For many years, researchers at Uppsala University have been exploring the genetic origins of the Scandinavian gray wolf population, which was founded by only three immigrating wolves. In their new study the scientists show ...

Humans and other primates have evolved less sensitive noses

Variations in the genes for the newly discovered scent receptors for musk and underarm odor add to a growing body of research suggesting that humans' sense of smell is gradually becoming less sensitive. Sijia Wang of the ...

Genetic strategy reverses insecticide resistance

Insecticides play a central role in efforts to counter global impacts of mosquito-spread malaria and other diseases, which cause an estimated 750,000 deaths each year. These insect-specific chemicals, which cost more than ...
