Amazing how much ‘common knowledge’ is absolute bunk. Journo takes it as axiomatic that such mixes cannot reproduce, and many think species are defined by what can and cannot interbreed.
Columbus also didn't ‘discover’ the world was round, it was common knowledge and the argument was not over the shape of the Earth but how far it was around (the figure of Eratosthenes was accurate, Columbus's figure made the journey optimistically shorter).
Okay ... I’m glad you agree with me...
