I would think a neurosurgeon should know a thing or two about biology.

actually, a really good neurosurgeon loses a lot of general scientific knowledge as time goes on.

the same is true of a lot of phds, they know a lot about a narrow subject but were actually a much more rounded scientist before they got their doctorate.

"I would think a neurosurgeon should know a thing or two about biology."

Biology is a big field. To quote Egnor himself...

Doctors don’t study evolution. Doctors never study it in medical school, and they never use evolutionary biology in their practice. There are no courses in medical school on evolution. There are no ‘professors of evolution’ in medical schools. There are no departments of evolutionary biology in medical schools.

Now to be honest there are many doctors who do study and use evolutionary biology, but clearly Dr. Egnor admits to having no such background himself.
