How did zebras get their stripes?

anyways, it's genetic.

"Bard's hypothesis that all the stripes originally are the same width and are generated at different times in the three species also explains the numbers of stripes in each species. The common zebra has 26 stripes per side, and the 3-week Equus embryo is generally 11 mm long. This gives a spacing of about 0.42 mm per stripe. If the 43 stripes of the mountain zebra were generated in the 17 mm embryo of the 3.75 week zebra, the spacing is also 0.40 mm per stripe. At week 5, the embryo is 32 mm long, and the 80 stripes would yield the spacing of 0.40 mm per stripe. Therefore, the striping patterns of the common zebra, mountain zebra, and imperial zebra can be explained if the stripes are generated 0.4 mm apart in the 3-, 4-, and 5-week embryos, respectively."

and, when i was looking for patterning in zebras, i found this:


killing a victim by imprisoning him for homosexuality and causing him great psychological distress seems to be a thing that the british court was very good at doing: Looks like they killed turing pretty much the same way they did it to wilde.

the law: Criminal Law Amendment Act 1885
