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

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.
