People residing in a place with warm and humid conditions commonly have wider noses, while those that live in cold and dry locations have narrower nose.
Is humankind getting dumber? Natural selection is working against humankind this time.
A new study reveals that same-sex sexual behavior actually has evolutionary advantage.
Poetry has always fascinated and provoked readers to think and understand the world in a deeper way. May nature lovers have used poetry to connect with what they experience every time they step out into the open.
Some prairie voles are monogamous, while others seek out multiple mates. In a recent study, researchers from the University of Texas at Austin reveal sexual behavior is largely controlled by genetic differences in the rodents' brains, suggesting natural selection has allowed for both characteristics to co-exist.
Fossilized peach pits unearthed in China suggest the deliciously juicy fruits were around long before humans began domesticating them.
Venom is both a predatory defense and a predator's advantage. While some venomous animals have recently evolved with more potent toxins, their ancient counterparts diversified less often. This suggests that the evolution of venom is more complex than previously thought.
CRISPR, a gene-editing system, could have serious consequences if rapidly spreading genes end up in the wrong species.
We all know that it's hard to keep up appearances when you're constantly on the go. That's why the fashion police will probably give some female warblers a free pass, even after researchers found that they boast drabber feather when their migration routes are particularly long.
For as long as it has been in society's crosshairs, homosexuality has been part of a very simple debate: is it natural or is it a choice? The question of whether it was helpful to a species was never considered; after all, do we question whether it's better for humanity to boast a specific eye color or personality? Now however, a new study has revealed that the trait can be very helpful to a species, and you won't believe how.
As humans, and especially for women, we love the idea of romantic relationships and finding "the one." But new surprising research says that we are actually designed to fall out of love and move on to new relationships.
It seems that a certain species of spider knows the meaning of survival of the fittest, according to a new study.
It may be one of the last examples of ongoing natural selection in humans. Pygmy hunter-gatherer tribes in Uganda have genes to thank for their incredibly small stature, and researchers now suspect that this trait has evolved several times to help these people better adapt to their unusual lifestyle.
