Genetic sharing among evolutionary neighbors all happens through hybrids: the offspring produced when individuals from two ...

Research into wood warblers shows that gene sharing across species played a key role in shaping their bright feather colors.

Wood warblers, also called New World warblers, are some of the most colorful birds in North America, with more than a hundred species in the family ranging in color from yellow, orange and red to blue ...

Research looks at the evolutionary pathways to differences in bird plumage patterns between males and females -- and concludes that birds are able to adapt their appearance with remarkable ease.

When male northern cardinals perch amid evergreens highlighted with a dusting of snow, well, winter doesn't get much more greeting-card gorgeous than that. Because they're so handsome, cardinal images ...

This is a preview. Log in through your library . Abstract Several hypotheses have suggested that delayed plumage maturation (DPM) in male birds evolves to increase crypsis or to deter adult aggression ...

From peacocks to birds of paradise, male birds are well known for showing off their brightly coloured plumage as a way of attracting a mate. However, new research has suggested that males birds may ...

In many bird species, males are easy to spot because of their bright, beautiful plumage. When the sexes diverge in coloring, females often have drabber colors. In one type of hummingbird, these color ...

Women who use typical male strategies to promote their careers are often not successful. Recent findings suggest that this strategy often leads to the opposite effect. Apparently certain behaviours ...

People typically think about evolution as a linear process where, within a species, the classic adage of "survival of the fittest" is constantly at play. New DNA mutations arise and get passed from ...
