An international team of researchers says a fish called Microbrachius dicki is the first-known animal to stop reproducing by spawning and instead mate by having sex. The primitive bony fish, which was about 8cm long, lived in ancient lakes about 385 million years ago in what is now Scotland. The research is published in the journal Nature. Lead author Prof John Long, from Flinders University in Australia, said: "We have defined the very point in evolution where the origin of internal fertilisation in all animals began. That is a really big step."

So wee Scottish fish invented sex—and this is how Scotland thanks them.

But the takeaway here is this: sex came along 385 million years ago. Homo sapiens came along 200,000 years ago. Sex is older, smarter, and more powerful than we are. It predates us by 384,800,000 years, and it will outlast us. It made us, and it can unmake us. One of the lies we're told as children—one of many—is that one day we will grow up and have sex. Not true. One day we grow up and sex has us.
