New research from the University of East Anglia shows that an evolutionary force known as 'sexual selection' can explain the persistence of sex as a dominant mechanism for reproducing offspring.
Scientists said Wednesday they had amassed the first evidence to back theories that people fall into two broad categories—promiscuity or faithfulness—when it comes to sex.
Sexual selection refers to species' selection for traits that are attractive to the opposite sex. This special type of natural selection enhances opportunities to mate, the tail of male peacocks being an iconic example.
What do you get when you mix theorists in computer science with evolutionary biologists? You get an algorithm to explain sex.
It may be hard to imagine competing over who gets to kiss a frog, but when it comes to mating, a new study concludes that some frogs have moved out of the pond onto land to make it easier for the male in the pair to give ...
When a female praying mantis bites the head off her sexual partner, it is probably not out of anger.
Sex with the lights on: Sexual selection increases the number of species and impacts global diversity
When you're a firefly, finding "the one" can change the world. Literally. A new study by UCSB evolutionary biologists Todd Oakley and Emily Ellis demonstrates that for fireflies, octopuses and other animals that choose mates ...
