I really enjoyed the article overall.

The section on Darwin was an eyebrow raiser. It makes sense to include someone like Darwin (very interesting and well known), but he's not a great example to compare to "normal" people (like the couple mentioned in the opening paragraph).

A 50 year old in the 1800s whose job was catching a ship to the other side of the planet is a little different when compared to a factory worker, software engineer, doctor, etc.

Also, what the fuck is this off-hand remark:

> Unfortunately, Mendel’s work was published in an obscure academic journal and Darwin never saw it—and in any case, Darwin did not have the mathematical ability to understand it.
