i have heard a theory that it started as a mutation from polio or something that they were vaccinating for in africa, and the usual method of obtaining weakened strains and/or antibodies was to use horses, but they're in short supply in africa, so someone tried using chimps and that's how the mutation happened. zero fucking idea if it's true, but it's better than fucking a chimp. you'd have to be beyond mad to try willingly and there's no fucking way you'd survive actual chimp rape. then again, maybe they had florida man on their squad. or a jeet.
