It's more like certain traits are selected for certain reasons. More 'petite' and 'flatter' women being more agile, tire slower, can help in hunts or as quick gatherers. Larger chested women would be able to care for multiple women's offspring due to higher production but big boobs are heavy so leaving safety would be a worse decision. Homo Sapiens are a jack of all trades, also genetics making no sense, makes perfect sense with natural selection being flawed.


Tldr: natural selection weird, big boobs good, small boobs good.

Evolutionary psychology starts to feel like cold reading at times. People can just list reasons as to why people like a certain thing and you can't really prove or disprove it, and you end up just going "alright I guess".
