and yes gene frequency changes do actually have to be demonstrated in order to call it evolution, you can't just handwave that part

There aren’t changes in the genetic contribution to height. I never claimed that. There have been changes in height over time due in part to selection and height being heritable

No, sorry, you misunderstand; what you claimed is that there have been changes in height *due to* the genetic contribution, i.e. changes in gene frequency. I think we agree on what you're claiming here, I just don't believe you

I’ll try to clear up what I’ve been saying many times over. People have gotten taller over time. Part of that—especially recently—has been due to nutrition. But also part of that is choosing taller mates, which is what the study I sent you shows.

OK, so nutrition accounts for that post-1800 spike. Cool. We agree on that. So, then: What *actual increase in height* are you claiming is caused by sexual selection? And what is your evidence that it *actually does* result from changes in gene frequency, i.e. evolution?

ok, that's kinda interesting, but wtf does it have to do with what we're talking about?

And yes, under the Merrill Webster definition sexual selection with consent chooses and disallows certain people to reproduce with other people. The link is just about sexual selection and height. This isn’t connected to one that had the conclusion you didn’t buy

It's just about sexual *behavior*, though, not about sexual selection (in the sense that causes actual evolutionary changes in a population)

Current day sexual choice is part of the study of sexual selection. I’ll avoid three replies and give you some training wheels on this one. Imagine circles laid on each other, one bigger than the the other. The bigger one is is sexual selection and the smaller is sexual choice

What the fuck are you doing talking to an actual scientist about "training wheels" dude

What do you want me say? He couldn’t understand why I sent the study, and I wanted to avoid the replies I saw in our future.

They didn’t understand you because you’re communicating wrong ideas poorly
