The vast majority of animals need to breed to reproduce. But a small subset of animals can have offspring without mating. The process, called parthenogenesis, allows creatures from honey bees to ...

“They could simply say that it’s very likely that dinosaur DNA carried the gene variant that allows for parthenogenesis.” With the discovery limited to one captive animal, many questions remain.

"But in parthenogenesis, the body finds a unique way of filling in for the genes usually provided by sperm." WORLD'S LARGEST ... "For more advanced animals like vertebrates, scientists think ...

Parthenogenesis has since been observed in a vast array of different animal species, particularly in snakes. And it’s also been found in birds, lizards, turtles and sharks. Now, of course ...

Some female birds, reptiles and other animals can ... have only noticed parthenogenesis when solo females had young or when researchers were monitoring a population’s genes.

Feldheim said he’s counted 15 species of elasmobranchs where parthenogenesis has been observed by scientists since then. The phenomenon has been observed in every class of animals, except for ...

Scientists have two main theories. The aquarium says Yoko's birth could be the result of either delayed fertilization or parthenogenesis, a rare form of asexual reproduction — in which offspring ...

the phenomenon of Parthenogenesis which, previously to Mr. Darwin's work on the Origin of Species, excited the interest and called forth the investigations of observers in much the same manner as ...

A larger number of species experience spontaneous parthenogenesis, best documented in animals kept in zoo settings, like the Asian water dragon at the National Zoo or a blacktip shark at the ...
