It's neither here nor there, but we've always felt alien life would be so different from our own that they'd be incapable of meaningfully distinguishing between humans and other apes, or even other mammals, vertebrates, etc. (adjust up and down the family tree to taste). https://twitter.com/stavvers/status/1287323294329446401

The idea that a being from another world, who evolved with an entirely different mechanism of hereditary, who might be composed of entirely different chemical elements, would recognise the *minute* sexual dimorphism in humans is self-evidently ludicrous.

They probably wouldn't even understand what sexual dimorphism - or sex in general - was. They'd have something utterly different, as most species on our own planet do.

Two broad categories within a species that engage in vigorous rubbing to bring about genetic recombination via procreation isn't even a universal on Earth, let alone the planet fucking Zog.

There's a line in the original Star Trek, when they discover long-lost warp drive inventor Zefram Cochrane on a distant planet, his life sustained by an Energy Being™, when Spock realises the cloud thing is female and in love with the strange Earthman.

"Male and female are universal constants" he says, sagely. And, let us tell you, that is amongst the least scientific things the show about a spaceship that could travel faster than light crewed by an alien-human hybrid with copper-based blood ever came out with.

We never noticed this, but we've just googled and they totally do! https://twitter.com/PrototypeCube/status/1287339783614865408?s=19
