The remarkable reason zebras have stripes - Cella Wright

Dig into the scientific theories of why zebras have stripes, and why this unique patterning sets them apart from their equine relatives. -- Zebras belong to the same equine family as horses and donkeys. After their lineage entered Africa, they evolved into three zebra species, lived in social herds, grazed on grasses, and evaded fierce predators. One mystery that has perplexed prominent scientists for decades is the matter of their coats: why are they striped? Cella Wright digs into the common theories about the unique patterning.
