A new study challenges long-standing expectations that men are promiscuous and women tend to be more particular when it comes to choosing a mate.
California Institute of Technology scientists say they have trained computers to analyze fruit fly behavior in find a genetic basis for it. The researchers said they have developed a computer program that can analyze aggression and courtship in fruit flies, opening the way for the scientists to perform large-scale, high-throughput screenings for genes that control such innate behavior. The program allows computers to examine a half an hour of video footage of pairs of interacting flies to...
German scientists say they've determined wild female chimpanzees copulate more frequently with males who share meat with them over long periods of time. Max Planck Institute for Evolutionary Anthropology researchers Cristina Gomes and Christophe Boesch said their findings strongly suggest that wild chimpanzees exchange meat for sex and do it on a long-term basis. Males who shared meat with females doubled their mating success, whereas females who had difficulty obtaining meat on their own...
SAN DIEGO, Feb.
Researchers at Uppsala University can now show that what is good for one sex is not always good for the other sex. In fact, evolutionary conflicts between the two sexes cause characteristics and behaviors that are downright injurious to the opposite sex.
Stegodyphus lineatus is the only European species belonging to the spider genus Stegodyphus. The males of this species are up to 12 millimeters long, while the females are up to 15 millimeters long. The coloration can range from whitish to almost black. In the majority of individuals, the opisthosoma is whitish with two broad black longitudinal stripes.

The other members of the family are Herman's Tortoise, Marginated Tortoise, and Horsfield's Tortoise. There are six noticeable differences between males and females of the Greek Tortoise. Males have a longer tail that tapers to an even point. The anal cavity opening is farther from the base of the tail on the male. The male's underbelly is somewhat curved, while females have a flat...
