LONDON (Reuters) - Sex has been a fact of life for at least 380 million years, longer than previously thought. Internal fertilization was widespread among prehistoric fish living on ancient tropical coral reefs in the Devonian period, research published in the journal Nature on Wednesday showed.

The discovery sheds new light on the reproductive history of all jawed vertebrates, including humans.

"It shifts how we think about how reproduction evolved. You're a jawed vertebrate and I'm a jawed vertebrate, so this is our own history," said Zerina Johanson, a paleontologist at the Natural History Museum in London.

Johanson and colleagues in Australia, where the fossils were unearthed, deduced that copulation was common among armored placoderms, extinct shark-like species, after finding embryos inside Materpiscis, Austroptyctodus and Incisoscutum placoderms.

The sad part about all this is that the poor tax payers in Britian had to pay for this useless research.
