One of the seven wonders for me is、Human ear shape。cats, cows and horses、There's nothing strange about elephant ears.、For some reason, the shape of human ears is curled up.、It's hard to imagine how it came to that shape (the rationality of evolution).。
ears、If it is an organ that senses sound (or air) waves,、Fish also have ears。Of course there are birds too.。Not only does it exist in both reptiles and insects, but、Even a horned owl? (Some scholars say it exists in plants too, but、I won't go into depth here)。fish ears、There is a place inside the head called the inner ear.、It seems to work almost like the human ear.。Also called lateral line、both sides of the body、They detect subtle changes in water pressure with sensory organs connected like a single line from head to tail under their scales.、It seems that human voices can be detected here as well.。In addition, a floating bladder can be used to amplify external sounds.、It is said that some fish can hear with their inner ears through nerves in their bodies.、It can be said that fish have multiple ears.。
Teleost fish have otoliths in their heads.、This keeps you in position underwater.。As a side note、fossil hunter、Not a rock hunter、People with a hobby called otolith hunters、Collecting otoliths of different shapes for each species of fish、Apparently there is also a world of maniacs who brag about the beauty of their shapes.。—In the human semicircular canals (not only in humans)、Probably most animals have otoliths、have almost the same functionality。If this peels off、Feeling dizzy。A fish that swims while swimming、Naturally, it is impossible to catch food.。``I'm glad I was born as a human'' and I want to thank God for having ``vertigo outpatient treatment.''。
Bird ears are inconspicuous。Apparently, the questioner thinks that "the concrete result of sketching" brings fun.、When I comb the feathers、There is a gaping hole on the side of the head, almost like a human ear.。The long-eared owl is a member of the owl family.、Exceptionally among birds, the ears stick out.。This is the origin of the name "eared owl".、Considering their lifestyle, which relies more on sound than eyes to determine the location and size of prey,、Even if you discount air resistance, there is probably some rationality.。-in any case、Considering the behavioral patterns and ecology of animals、The origin of those ear shapes、I feel like it's pretty convincing。
Nevertheless、Why are human ears shaped like this?。The shape of a magatama (magatama) looks like the Arabic numeral 6 (the number we rely on the most on a daily basis) is carved out twice (the god of manga).、Osamu Tezuka's character's ears)、What kind of rationality is there?。I feel this every time I sketch a person.、A long-standing “mystery”。
