While this scientist is a clearly-stated atheist and evolutionist, he still gives a very interesting chat about why humans are different from all the animal kingdom. It’s a little sad this knowledge doesn’t lead him to explore the idea of a Creator, but that’s his own thing.
He does talk science behind ovulation and such, so young’uns might not be interested.
