We are probably the most beautiful generations of humans if we assume that attractive people tend to pass on their genes more. amirite?

The sense of beauty changes a lot with respect to environment.

In Africa (don't remember the country), there was a survey made to assess the beauty factors. Mostly women who were slightly fat were deemed beautiful. At the same time, the country had very high HIV positivity rate. As infected individuals tend to look weak and thin, the perception of being fat was deemed beautiful.

I mean. What is beautiful? That's different to everyone. So therefore there cannot be a real measuring stick.

Also, to add to this, are we talking about personality here or looks, because if it's looks, are we considering make-up and plastic surgery? If so, before or after? Because there are too many people altering their bodies to look more ‘beautiful', so is that still a fair trial?

Conventionally attractive people, sure I can agree with that. But other than that, we as a species are pretty bloody awful. The atrocities committed in the last 50 years alone are enough to make most extraterrestrial civilizations probably view us as a stain on the universe.

Attraction doesn't pass on. Persistance does

The problem with this is that standards of beauty change throughout time and throughout culture.

Except they're all getting killed by ugly psycho killers
