Discovery - Sexual Nature 1/3
Adam Rutherford explores the distant history of sex through three remarkable fossils – a pair of mating turtles, an armour-plated fish and some tiny ancient seaweed.
The oldest known sexual beings, a 400 million year old fish sex movie and the prehistoric turtles which were fossilised in the act of copulation. Discovery this week is strictly adults-only as we begin a three-part natural history of sex. Adam Rutherford talks to the scientists studying the world’s most revealing fossils.
