vii Ways Animals Are Like Humans

Animals and Humans

Nosotros humans like to think of ourselves as a special bunch, simply it turns out we have plenty in common with other animals. Math? A monkey can do it. Tool employ? Hey, even birds have mastered that. Civilisation? Lamentable, folks — chimps have information technology, likewise.

Hither's a listing of some of the top parallels betwixt humans and our fauna kin. Y'all may be surprised at how similar we are to even our afar relations.

Ears Like a Katydid

Humans have complex ears to translate sound waves into mechanical vibrations our brains tin process. So, every bit information technology turns out, do katydids. According to inquiry published Nov. 16, 2012 in the journal Science, katydid ears are bundled very similarly to human being ears, with eardrums, lever systems to dilate vibrations, and a fluid-filled vesicle where sensory cells wait to convey data to the nervous organisation. Katydid ears are a bit simpler than ours, but they can likewise hear far above the human range.

Worlds Like an Elephant

Humans do reign supreme in the loonshit of linguistic communication (as far as we know), but even elephants tin can figure out how to make the same sounds nosotros do. According to researchers, an Asian elephant living in a South Korean zoo has learned to use its body and throat to mimic human words. The elephant can say "hello," "expert," "no," "sit" and "lie downwardly," all in Korean, of course.

The elephant doesn't announced to know what these words mean. Scientists think he may take picked upwardly the sounds because he was the only elephant at the zoo from when he was 5 to when he turned 12, leaving him to bail with humans instead.

The Facial Expressions of a Mouse

Do you make weird faces when y'all're in hurting? So do mice. In 2010, researchers at McGill University and the University of British Columbia in Canada found that mice subjected to moderate pain "grimace," but like humans. The researchers said the results could be used to eliminate unnecessary suffering for lab animals by letting researchers know when something hurts the rodents.

The Slumber-Talk of a Dolphin

Could nosotros someday exist able to talk to dolphins? Hither, Fellow Richter monitors the jiff-holding adequacy of Puka, a bottlenose dolphin at UC Santa Cruz's Long Marine Laboratory. (Epitome credit: T. M. Williams/UCSC)

Dolphins may sleep-talk in whale song, according to French researchers who've recorded the marine mammals making the non-native sounds late at night. The five dolphins, which live in a marine park in France, have heard whale songs only in recordings played during the twenty-four hour period around their aquarium. Merely at night, the dolphins seem to mimic the recordings during residuum periods, a possible form of sleep-talking. And you idea your nocturnal mumblings were weird.

The Business firm-Building Skill of an Octopus

Okay, Frank Lloyd Wright's "Falling Water" it is not, but a home built past an octopus has the advantage of being mobile.

The veined octopus (Amphioctopus marginatus) can make mobile shelters out of coconut shells. When the animal wants to movement, all information technology has to exercise is stack the shells like bowls, grasp them with stiff legs, and waddle away along the ocean floor to a new location.

The Movements of a Brittle Star

It'd exist difficult to imagine an organism less like a human than a breakable star, a starfish-similar creature that doesn't even take a central nervous organization. And yet these five-armed wonders move with coordination that mirrors human locomotion.

Brittle stars have radial symmetry, pregnant their bodies tin be split into matching halves past drawing imaginary lines through their arms and central axis. Humans and other mammals, in comparing, have bilateral symmetry: You lot tin split united states in half ane manner, with a line drawn straight through our bodies. Most of the time, animals with radial symmetry movement little or move upward and downwardly, like a jellyfish that propels itself through the h2o. Brittle stars, however, move forward, perpendicular to their torso axis — a skill usually reserved for the bilaterally symmetrical.

Brain Like a Pigeon

Gamblers in Vegas have something in mutual with pigeons on the sidewalk, and information technology's not just a fascination with shiny objects. In fact, pigeons brand gambles merely like humans, making choices that leave them with less coin in the long run for the elusive promise of a big payout.

When given a choice, pigeons will push a button that gives them a big, rare payout rather than one that offers a small reward at regular intervals. This questionable decision may stem from the surprise and excitement of the big reward, according to a report published in 2010 in the journal Proceedings of the Royal Society B. Human being gamblers may be similarly lured in past the thought of major loot, no matter how long the odds.
