In the original cosmos Carl Sagan says there are crabs that resemble the Japanese samurai mask and the reason for this is the samurai liked that the crabs looked similar to their mask so they threw them back in the water to preserve them, basically breeding them.
But I have a suspicion that the samurai saw the crabs "FIRST" and they modeled their mask "AFTER" the crabs, meaning they copied the crabs.
Is my guess possible?
