people loooove to say that men and women are fundamentally different because biology. But when you actually look at the DNA, the building map for our bodies, the things that determine our physical characteristics, only 1 out of 23 chromosomes are different. When you also take into account that humans have two sets of chromosomes, it turns into 1/46 since "female" is XX and "male" is XY. 1 in 46.

2% of our DNA is different on the basis of sex.

Which means that 98% of our DNA is the same. If almost any other two things were 98% identical, we'd just round up and call it close enough for most contexts.

But because it comes down to segregating people into groups and basing their societal worth in it, that 2% difference is used as the basis to claim that we are so different from each other, that we're fundamentally different species.

And this is a VERY GROSS oversimplification of how DNA works. Some people have multiple X or Y duplicates, and were still researching how these duplicate genes can impact development. We still don't completely understand our physiology very well in the grand scheme of things, and as of this post we haven't decoded the entire human genome yet. There's still so much we have to learn.

So yeah, separating "men" and "women" and treating them like completely separate species, when in fact we are approximately 2% different on a biological level??? What are we doing.
