The basic body plan is female, and males are 'customized females'. Male breasts are vestigal.

I heard a podcast once with two male biologists talking to each other. One of them said "The world is female, and males are only around to do the absolute minimum necessary."

Bad news, it was Dickson Despomier who said it to Vincent Raccionello, and they have hundreds of podcast episodes. You're best chance would be to email Dickson or Vincent to see if they remember the context.

That's a pretty popular podcast. I would be surprised if they aren't all AI transcoded and the text of them on the internet somewhere.

women have breasts to 'generate milk' and 'because they look nice'

men have breasts because they're 'fat'

a vicious double standard

Ehhh, it's not quite that cut-and-dry. Hormones are a fuck
