First penises nature has given an L-shape – TVNZ

All earlier and earlier

Professor John Long (John Long) from Flinders University (Flinders University) in Adelaide and his colleagues from the Museum of Victoria in Melbourne for several years “sexually concerned “- looking for living beings, who were the first on our planet began to engage in sexual intercourse. That is, the first retreated from the prehistoric method of reproduction. So-called external. When the female lays eggs and the male pours her cum. So primitive and bleak, as we know, are still available on the majority of fish. And the frogs do not disdain.

Five years ago, scientists have found bidders – fish, similar to modern sharks. They took as much sex 380 million years ago. And recently learned about a new discovery – about copulating partners, in the full sense of the word, 50 million years earlier – 430 million years ago. They were so-called armored fish Microbrachius dicki, cillations in that distant time in the lakes on the territory of modern Scotland.

Peredki modern penises were in the form of letters L

Suspicion of fish the size of about 8 inches fell after Professor Long saw in fossilized remains of a male Microbrachius dicki outgrowth of unknown purpose. He – appendix – was located in the tail was bent and the letter L. Soon scientist with colleagues guessed the appointment – it’s a penis! The first penis!

appendage was stocked with grooves in which sperm gets to the female. In females the same Microbrachius dicki found special bony plates that form a gap and clamped outgrowth during intercourse.

First sex sideways

As explained by Professor Long, L-shaped bend of manhood allows the couple to engage in sexual intercourse, while sideways to each other. After all, different positions, owing to its distinct shape, the fish could not practice.

Located more or less convenient, Microbrachius dicki hugging each other fins like arms. And establishing genital contact, began to “dance”.

Scientists claim that intercourse gave fishes fun, otherwise they would not engage in them. Although female genitalia were gruff – like graters for carrots. But they are well kept male body in the process of fertilization.

The first penis was a length of 1 centimeter. For the male length of 8 inches – very impressive. If men had such dignity – in the eighth part of the body, with an average growth of 170 centimeters, they – dignity – would reach 21 centimeters.

BEFORE

After 50 million years – not sideways

In earlier studies professor Long, again considering the fossils found in one fish smaller fish. At first I thought, if they were swallowed. But then found that “fry” – embryos. This was reinforced by a kind of umbilical cord. In other words, the fish – an ancient shark Incisoscutum ritchie – was pregnant. Scientists have suggested that if there is a nurturing, you are obliged to be sex. Internal fertilization, or, to put it in scientific terms.

Soon of fossils found and the male genitalia. In males, the ancient shark was already on two penises. They settled down a little further lower fins. Were like them, but the fins were not.

– The ends of these processes were the erectile aids, – said John Long. – They were introduced into the body of the female and used to deliver the male gametes.

In this case, according to the scientists directly lower fins male female bowed, reciprocating motion – natural sex. And not sideways.

So, sex began to engage in at least 430 million years ago. After 50 million years, the process is not stalled. On the contrary, took almost the entire planet. Thanks to ancient fish. There is who to thank for the current charms of life. And it would still threw eggs. No pleasure.
