In birds, expecting to mate leads to higher fertilization rates

From an evolutionary perspective, the primary task of an organism is to pass along its genes to future generations. Such genetic transmission is usually assumed to be instinctive. However, a new study shows that species also learn to adapt to their surroundings in order to increase their reproduct...

Species still have more viable offspring if they can choose their best mate

Athens, Ga. -- When it comes to picking a mate, Crosby, Stills, Nash and Young had an answer: If you cant be with the one you love, love the one youre with. As it turns out, that may be a cardinal rule in the animal kingdom, too. New research that crosses several species boundaries shows that ...

Female pronghorns choose mate based on substance as well as show

When a female animal compares males to choose a mate, she can't order a laboratory genetic screen for each suitor. Instead, she has to rely on external cues that may indicate genetic quality. Until now, biologists have focused on elaborate ornaments, such as the peacock's tail, as cues that females...

Rutgers researchers scientifically link dancing ability to mate quality

Dance has long been recognized as a signal of courtship in many animal species, including humans. Better dancers presumably attract more mates, or a more desirable mate. What's seemingly obvious in everyday life, however, has not always been rigorously verified by science. Now, a study by scienti...
