WHERE DID THAT BABY SHARK COME FROM?

May 2007

A female bonnethead shark (part of the hammerhead family) gave birth to a pup (yes, some sharks are viviparous – this was very important for realising that mammals have eggs. Read my book!). What was interesting is that she had not been in contact with a male – it was a case of parthenogenesis, unusual in such a large animal. Original article in Biological Letters (open access), BBC news item.
