Why Do Zebras Have Stripes?

New Study Makes Temperature Connection

A leopard may not be able to change its spots, but some zebras change their stripes. Zebras in warmer places have more stripes, a new study shows, which might help answer an age-old question: Why stripes?
The answer probably comes down to keeping zebras cool and fending off disease-causing insects that are more common in hotter climates, researchers reported in the journal Royal Society Open Science.
