The human brain didn’t expand that recently, and this part of the summary makes it sound like it. But this is not only a fault of the summary: in the transcript Connor does mention that one of the factors causing sharp turns where marginal increases to intelligence (as demonstrated by brain size), and later mentions 10.000 and 150 years ago as main examples of SLTs (when, of course, the brain size didn’t change).
Being more charitable (since the text is messy), maybe he just meant brain size is evolutionary evidence of how valuable marginal increases in intelligence is (the power of intelligence). But then this doesn’t seem relevant to discuss the sharpness of SLTs.
The “1000” instead of “10000″ was a typo in the summary.
In the transcript Connor states “SLT over the last 10000 years, yes, and I think you could claim the same over the last 150”. Fixed now, thanks for flagging!
Should be 10.000. Which is relevant to:

Yes, that’s what I meant, sorry for not making it clearer!
