If you’ve ever been told that masturbation is unnatural, evolutionary biologist Matilda Brindle begs to differ. Indeed much of the animal kingdom is at it, if her fascinating article about its evolutionary reasons is anything to go by. Primates, the animal group humans belong to, seem particularly dedicated to self-pleasure.
Testing the idea that masturbation may help protect animals from sexually contracted infections and boost their chances of passing on their genes, Matilda has found evidence that self-gratification has given an evolutionary advantage to male primates since at least the ancestor of all monkeys and apes, including humans. Unfortunately, things aren’t so clear for females.
Meanwhile, research shows that though there are many benefits to eating fruit and vegetables, plant foods that are rich in compounds called flavanols may be more helpful than others. Here’s what you need to know.
And late last year, scientists recorded one of the brightest explosions in the universe ever known. Now, astronomers think they may have figured out why it happened.
