On Radio 4 this morning Prof Steve Jones was saying that it's because flying insects don't like stripes, but they don't yet know why.

I'm thinking that if flying objects are going to land rather than crash land they have to be able to judge distance accurately, and if the target is striped it's easy to misjudge distance using binocular vision when each eye focuses on a different stripe.

Animals with flexible vocalisation and small family groups have names. Zebras have bar codes.

Too big for the supermarket checkout!
and the misguided shall lead the gullible,
the feebleminded have inherited the earth.

No, neigh, never.
But just realised it's only sheep that have baa codes.
