Whom needs males, anyhow?

Apparently perhaps perhaps perhaps not sharks that are leopard. Early in the day this week, the Reef HQ Great Barrier Reef Aquarium in Queensland, Australia, welcomed three shark that is leopard from the mom that has no connection with a male. The for Quartz.

just How is this possible? It’s a procedure called parthenogenesis (pdf), in other words. virgin birth, and we all know it takes place among some forms of wild wild birds, snakes, and lizards. In reality, it probably occurs in nature on a regular basis, states Warren Booth, an evolutionary biologist during the University of Tulsa in Oklahoma.

“Cloning is once you create a copy that is exact of mom,” Booth claims. “Virgin birth is somewhat various. Parthenogenetic offspring are half-clones associated with the mother.”

Here’s how it functions: whenever some types of animals—really, any female that is non-mammal a back and a jaw—reproduce, they make egg cells which have 50 % of their hereditary information, just like animals do. However in parthenogenesis, in place of fusing the egg cellular with DNA from the cell that is male these cells either increase their very own hereditary information, or set up with another ovum that features an alternative 50 % of hereditary information.
