Catherine Scott is a graduate student working toward her Ph.D. at the University of Toronto. She’s studying the courtship behavior of black widow spiders. That means that her experiments often involve waiting for spiders to have sex.
People who use dating app Tinder judge possible hookups just by looking at faces, making instant decisions based on attractiveness. But apparently those decisions aren’t based on some evolutionary instinct — they come from personal experiences.
When they’re courting, male Carola’s Parotia put on one hell of a show. Whenever this bird-of-paradise from New Guinea gets females to visit his painstakingly-prepared display court, he runs through six specific dance moves, each of which has to be performed well, and in the right order, to convince a female he’s a…
Menopause is one of the oddest features of human reproductive biology. Not the hot flashes or the forgetfulness, but the fact that older women lose the ability to have babies. Now researchers say that once it appeared, menopause may have had a ripple effect on human mating that helped create the human pair-bond.
In 2011, a remarkable and distinctly erotic 17th century portrait of Nell Gwyn was put up for sale by her descendants. It shows Gwyn, an actress who was one of Charles II’s mistresses for more than a decade, washing a string of sausages with her breasts exposed.

Male kangaroos and wallabies, like a lot of seemingly quiet grazing animals, get into knock-down drag-out fights over females. They obviously don’t have antlers or horns to spar with, but they’re perfectly willing to grapple rivals with their forelimbs and kick the crap out of each other with their big hind feet.
The twinkly flashing lights of fireflies are a classic sign of summer, but the insects aren’t blinking for your aesthetic benefit. They’re courting in an absolutely cutthroat meet market, and some scientists are afraid that human activities could be making it harder for them to succeed. This summer, you can help…
These enormous antennae are for more than just show. The male glowworm beetle needs them if he’s going to track down a female. It’s not that lady glowworms are shy, they can’t go looking for males. They have no wings.

Let’s hear it for newly-discovered species with interesting sex lives! A pufferfish that builds complex circular spawning nests and a frog that gives birth directly to live tadpoles have been picked as two of the the International Institute for Species Exploration’s “top 10” new species of 2015.
Humans use all kinds of gimmicks to win over mates — but you’d think that in nature, it would be all about honest competition.
