Evidently perhaps not leopard sharks. Earlier in the day this week, the Reef HQ Great Barrier Reef Aquarium in Queensland, Australia, welcomed three leopard shark pups from a mom who’d no connection with a male. The for Quartz.
Exactly exactly How is it possible? It’s an ongoing procedure called parthenogenesis (pdf), for example. virgin birth, and we all know it takes place among some kinds of wild birds, snakes, and lizards. An evolutionary biologist at the University of Tulsa in Oklahoma in fact, it probably happens in nature all the time, says Warren Booth.
“Cloning is once you create a copy that is exact of mom,” Booth claims. “Virgin delivery is somewhat various. Parthenogenetic offspring are half-clones regarding the mom.”
Here’s how it operates: When some types of animals—really, any non-mammal feminine with 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, in the place of fusing the egg cellular with DNA from a cell that is male these cells either increase their hereditary information, or set up with another ovum that includes a different sort of 1 / 2 of hereditary information.
