While seeking evidence of inbreedin

While seeking evidence of inbreeding, the researchers found something surprising. About 3 percent of the fish resulted from parthenogenesis. This was totally unexpected. Normally, vertebrate offspring that are born this way die or are stillborn. But these sawfish all appeared fine.

Scientists don’t yet know how common parthenogenesis is in the wild. Chapman says it may be more common in very small populations, where females have trouble finding mates. This reproductive tactic may help a species avoid extinction — at least for the short term. “But only females are produced,” Chapman notes. “So it won’t work forever.” The only hope for a male to be produced is for a female to mate with a male, he says. And a healthy population ultimately will need males to survive.
