There’s a whole band of pets who don’t require males to reproduce

Whom requires guys, anyhow?

Evidently perhaps perhaps maybe not sharks that are leopard. Previously this week, the Reef HQ Great Barrier Reef Aquarium in Queensland, Australia, welcomed three shark that is leopard from the mom who’d no connection with a male. The for Quartz.

Just How is this feasible? It’s a process called parthenogenesis (pdf), in other words. virgin birth, and it is known by us occurs among some kinds of birds, snakes, and lizards. In reality, it most likely takes place in nature on a regular basis, states Warren Booth, an evolutionary biologist during the University of Tulsa in Oklahoma.

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

Here’s how it operates: whenever some types of animals—really, any female that is non-mammal a back and a jaw—reproduce, they generate egg cells which have 1 / 2 of their hereditary information, just like mammals do. However in parthenogenesis, rather than fusing the egg cellular with DNA from a cell that is male these cells either increase their very own hereditary information, or set up with another ovum which has an unusual 50 % of genetic information. It’s type of like two eggs fusing together to produce an embryo—something that might be impossible in animals like us.

As cool as half-clones noise, they aren’t specially healthier variations of those pets. “What’s occurring is you’re creating a really organism that is highly inbred” Booth claims. […]
