Humans share 50% DNA with bananas
Eat a banana of the variety typically sold in American markets, then a plantain, then one of the short, fat, thin-skinned deliciously sweet kinds seldom sold here. Then tell me they are all the same.
Kinda like saying that iguana, rattlesnake and capybaras "all taste like chicken".
And yes, there are many variations, but the example would be like Great Danes, Pekingese, and beagles...very different but still the same species.
