That analogy is not useful at all. Continents are not biological organisms.
>Genetically brown and polar bears can and in reality often do interbreed producing viable offspring and exchanging genetic information between populations
And yet they are separate species. Just like the 4 separate species of giraffe the article is about, which can and do all interbreed. The concept of species is in no way reliant on an inability to produce fertile offspring.

The great thing is different countries use different definitions yet people seem to assume whatever they grew up with is correct. https://en.wikipedia.org/wiki/Continent#/media/File:Continental_models-Australia.gif https://en.wikipedia.org/wiki/Continent#/media/File:Continen... At most you can say brown and polar bears are "generally classified as separate species" But, there really is debate on this topic.
