A stealthy, stronger line of female salamanders are skipping sex and stealing DNA from males instead
The stolen genetic material triggers them to lay eggs virtually free of the unwitting sperm donors’ genes.
It’s a reproductive strategy known as “kleptogenesis”—essentially, reproduction by theft.
“On paper,” Denton said, “it’s the perfect way to reproduce: there are no males to take up resources, every female gets to pass on all of her genetic material, but they still get a new shot of genetic variation occasionally.”
