...specifically, when there is variation with respect to a trait, those variants differ in the numbers of offspring produced, and this variation is heritable to some degree...
No no no Mr. PHILOSOPHY.....it's "specifically" when those variants differ in the numbers of offspring produced THAT REACH REPRODUCTIVE AGE AND PASS THE VARIANT OFF TO THEIR OFFSPRING.
Simply varying the numbers of offspring produced means NOTHING concerning "selection." Simply having offspring inherit a trait means NOTHING concerning "selection".....you must pass the trait off to offspring WHO PASS IT OFF TO OFFSPRING.

Oooooo.....it was published in Science......that must mean it's a piece of peer-reviewed research, right? It's not just a book review, publishied without peer review....of a philosopher's book, reviewed by another philosopher?
It was published in “Nature” not “Science.”
“Nature” does publish a lot of philosophy without the rigid requirements of other periodicals. It does not promote itself as a scientific journal - it’s a magazine for entertainment and a lot of gee-whizzing.
That said, the CEH clip (they don’t actually have articles just sound bite sized snippets) doesn’t say anything of value for criticism. It’s just a brow raise and a move along.
