I'm literally asking you to get specific so we can talk about particulars, so I'm not sure where you're getting that from.

You're still not providing any citations, why is that?

It's not about what motivates me, it's about the scientific consensus in the field of biology. The same consensus that has remain unchanged for well over a century. I've provided citations affirming this consensus, and you've refused to back up your comments. Why not just admit that you're wrong?

EDIT: Rate limited by HN, so I guess we are done here. I'm not sure why you think prompting you to get specific about the group means being unaware of it. I'm rather disappointed in your bluster, it makes me wonder in retrospect if I've been baited into arguing with a bot.
