Overtaken by Events

About a month ago, I posted a bit of speculation, stemming from David Reich's Who We Are and How We Got Here, in connection with the expansion of the Yamnaya people into Europe five thousand years ago.

In the introduction, Reich makes it clear that the field of ancient DNA studies is in rapid flux, and that any claims in the book are subject to change.

Well, the very item that I talked about has been voided; plague hit Europe before the Yamnaya got there.

Three-Day Weekend

The finals are all in; the last of them dropped into my mailbox yesterday afternoon. Twenty-one group theory tests, eighteen foundations of geometry, five real analysis. (None of the later geometry tests was anywhere near as big as the first. Thank heaven for that!) Final grades have to be submitted by noon Monday.

I know what *I'll* be doing this weekend...
