Helps to explain why the zebra has stripes:
Painting a cow to look something like a zebra has been found to reduce fly bites by 50%.
Which leads to something I don’t know. Tsetse flies mean chunks of Africa can’t be used for cattle raising, nor, I think, horses. Not so much the fly I think, but some parasite their bite passes on. (!?!)
Zebras are of course closely related to horses, it’s possible to breed a zhorse or summat, as with a mule from a horse donkey combination – and the donkey zebra cross is definitely possible – but what is it that leaves the zrbra free to breed in tsetse areas? Is it immunity to the parasite? Or being bitten less? And if the second, is that the reason for the stripes? Or even, did they develop before the immunity did.
And another question. I know there was a big trade in horses from the steppes down into India. And also from N Africa down into tropical.
Is it because horses don’t breed, or don’t do so well, in hot climates? Or just the economics of billions of acres of grassland?
