So, I'd like to take the devil's advocate point of view. When you said that we are constantly evolving, but we are definitely of different race, different cultures, different— we have now an AI-dominated society, everything is evolving, but we have the same blood color, for instance. Right. So, we have certain things which are constant. We have different DNAs, we have different fingerprints, but we have the same organs. Like, we have 2 eyes, 1 nose, 1 mouth. That is not evolving. So when we are looking at this, when I'm talking from the point of view, opposite point of view, this is not— it's not something we can evolve.
Suddenly somebody cannot come tomorrow with 3 eyes. Um, yes and no. Human beings are evolving as a biological species too. For example, we had muscles in our ears which moved. They don't move anymore. They're called vestigial organs. A lot of our organs are not functional anymore. We call them
