 | A group of five endemic Hawaiian songbird species were historically classified as "honeyeaters" due to striking similarities to birds of the same name in Australasia. Scientists at the Smithsonian Institution, however, have discovered that the Hawaiian birds share no close relationship with the other honeyeaters and in fact represent a new family of birds -- unfortunately, all members of the new family are extinct, with the last species of the group disappearing about 20 years ago. ...> Full Article |
The amount of proteins produced in cells -- a fundamental determinant of biological outcomes collectively known as gene expression -- varies in African-American individuals depending on their proportion of African or European genetic ancestry. These findings, by researchers based in Boston, Philadelphia and Oxford, are published Dec. 5 in the open-access journal PLoS Genetics.

New research suggests that relatively recent events had a substantial impact on patterns of genetic diversity in the southwest region of Europe. The study, published by Cell Press on Dec. 4 in the American Journal of Human Genetics, shows that geographical patterns of ancestry appear to have been influenced by religious conversions of both Jews and Muslims in the Iberian Peninsula.
