Gender of many reptiles, including crocodilians and turtles, is largely determined by the temperature in which eggs incubate. When taking a closer look at the molecular mechanisms behind this phenomena known as temperature-dependent sex determination, researchers discovered a thermosentive protein inside the egg plays a key role.
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.
A yellow-bellied watersnake gave birth for the second time in it's life without genetic contribution of a male in a rare process known as asexual reproduction.
When it comes to chimpanzees, it seems that the "new girl" may have the upper hand in former stronger female bonds, new research says.
Scientists have long been curious as to why it's common for animals to fight with members of other species, and now a new study has found the answer, blaming it on females, of course.
Unique regulatory "tags" found in male sperm could cause autism in their children, according to a new genetic study.
Researchers have revealed a bizarre evolutionary twist to deep-sea "bone-eating" worms, an already unusual species, a new study says.
Chimpanzee mothers with sons are about 25 percent more social than moms and daughters, allowing their young boys to watch and learn from adult males in action, a new study indicates.
It seems that female chimps are essentially bullied into mating, as new research shows aggressive males of this species are more likely to father offspring over time.
We all know that men are from Mars and women are from Venus, and a new study supporting this way of thinking shows that male brains - at least in nematodes - are wired to choose sex over food, whereas the same doesn't ring true for females.
