Getting it on nearly 410 million years ago! Ahh yeahhh!
A new study by scientists hints that fish were the first animal to have intimate sex, not only for copulation, but for enjoyment!
Scientist have been studying fossil embryos that suggest fish evolved the ability to have intimate sex by copulation.
Recent genetic analysis of the fish fossils indicates that the same genes responsible for making our limbs, and the pelvic fins of fishes, also played a role in developing the sexual organs of our very distant ancestors.
Wooh – far out!
It seems that limbs and genitals developed via the same developmental pathways, so fossils showing the oldest evidence of pelvic fins (the placoderms) also showing the oldest expression of sexual organs (claspers) might not be such a coincidence.
It doesn’t mean that much to us, but the scientific community is buzzy about it!
