Youi had mat ridley on the podcast few weeks ago his book virel. They kind of stage a debate, stage of debateu an, they kind of give the debate of the lableke versus the zonomic a spread hypotheses. By the time i read the book carefully, and it's not clear, it's like 50 50, or maybe 51 forty. Aman could go either way. We just still don't know. And you can't trust the chinese for the information they're giving us. Anyway, that's the point of your book, ri yaku, thank you so much.
