Swiping too fast on Tinder can skew your perceptions of attractiveness, which can make it more difficult to find the right potential mate for you.
Among the insects known as burying beetles, females are more attracted to smaller males because they are, you know, chill. That is, they're less likely to get into fights when competing for mates.

A 'supergene' that affects a male ruff bird's plumage ultimately determines its mating strategy.
Heavy metals such as mercury, chrome and copper alter the brightness of some birds' feathers, making them seem less attractive to females.
Lizards use bright colors to attract mates but this also makes their camouflage less effective, making them visible to predators, report researchers from the University of Cambridge.
Researchers have long understood that male mice sing, or use vocalizations, to attract their mates. However, a recent study using specialized microphones found that the female mice sing back – but only if they're interested.
Birds that are able to mate with their "true love" have a higher rate of reproduction success and are more committed to their offspring, according to researchers from the Max Planck Institute for Ornithology.
A recent study observed the reproduction success of male orangutans. They found that females are more attracted to males with padded cheeks.
