The Slightly Striped Quagga
extinct quagga, a subspecies of the zebra from the Cape Province in South Africa,
provides another piece of evidence in support of the fly-hypothesis. Coming from tsetse-fly infested areas further North, the fully striped predecessors of the quagga migrated to an area free from tsetse fly infestations. It seems that the animals now had no more
need for stripes and that these gradually faded over many generations. By the time
the quagga was driven to extinction around 1870, only the head, neck, and tail were still faintly striped. The quagga is displayed in the Museum für
Naturkunde in the same room as the zebra.
