A new Nature paper on placoderm fossils is TRULY sexy science! – With a video to prove it! #science

A new study from Flinders University is some of the sexiest science I have seen lately… literally. The study documents the earliest instance of sex involving penetration for sperm transfer and was published in Nature.

A profound new discovery announced in Nature today (October 20, 3:30am, ACDT) by world-renowned palaeontologist, Flinders University Professor John Long, reveals how the intimate act of sexual intercourse first evolved in our deep distant ancestors.

In one of the biggest discoveries in the evolutionary history of sexual reproduction, Professor Long has found that internal fertilisation and copulation was invented by ancient armoured fishes, called placoderms, about 385 million years ago in Scotland.

The video below is a terrific visual summary of the study!
