Can Animals See More Colors Than Humans

vii Means Animals Are Like Humans

Animals and Humans

We humans similar to think of ourselves as a special agglomeration, but it turns out we have plenty in common with other animals. Math? A monkey can do it. Tool use? Hey, fifty-fifty birds have mastered that. Civilization? Sad, folks — chimps have it, too.

Hither's a listing of some of the top parallels between humans and our animal kin. You may exist surprised at how similar nosotros are to even our distant relations.

Ears Like a Katydid

Humans have circuitous ears to translate sound waves into mechanical vibrations our brains tin can process. So, equally it turns out, practice katydids. According to research published Nov. 16, 2012 in the journal Scientific discipline, katydid ears are bundled very similarly to human ears, with eardrums, lever systems to amplify vibrations, and a fluid-filled vesicle where sensory cells await to convey information to the nervous system. Katydid ears are a bit simpler than ours, but they tin likewise hear far in a higher place the human range.

Worlds Similar an Elephant

Humans do reign supreme in the arena of language (as far as we know), but even elephants can figure out how to make the aforementioned sounds nosotros do. Co-ordinate to researchers, an Asian elephant living in a Due south Korean zoo has learned to use its trunk and pharynx to mimic human being words. The elephant can say "hello," "skillful," "no," "sit downwardly" and "lie down," all in Korean, of course.

The elephant doesn't appear to know what these words mean. Scientists think he may take picked up the sounds considering he was the but elephant at the zoo from when he was five to when he turned 12, leaving him to bond with humans instead.

The Facial Expressions of a Mouse

Do y'all brand weird faces when you're in pain? 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," just 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 Sleep-Talk of a Dolphin

Dolphins may sleep-talk in whale song, according to French researchers who've recorded the marine mammals making the non-native sounds tardily at night. The five dolphins, which alive in a marine park in France, have heard whale songs merely in recordings played during the twenty-four hours effectually their aquarium. Just at night, the dolphins seem to mimic the recordings during rest periods, a possible form of sleep-talking. And you thought your nocturnal mumblings were weird.

The House-Building Skill of an Octopus

Okay, Frank Lloyd Wright's "Falling H2o" it is not, just a home built past an octopus has the advantage of being mobile.

The veined octopus (Amphioctopus marginatus) tin make mobile shelters out of coconut shells. When the animal wants to move, all it has to do is stack the shells similar bowls, grasp them with stiff legs, and waddle away along the sea floor to a new location.

The Movements of a Brittle Star

The brittle star doesn't turn as most animals do. It simply designates another of its five limbs as its new front and continues moving forward. — The breakable star doesn't turn as most animals do.

Information technology'd be hard to imagine an organism less like a homo than a brittle star, a starfish-like creature that doesn't even accept a fundamental nervous organization. And yet these five-armed wonders move with coordination that mirrors man locomotion.

Brittle stars have radial symmetry, meaning their bodies can exist split into matching halves by drawing imaginary lines through their arms and fundamental axis. Humans and other mammals, in comparison, have bilateral symmetry: You tin can split us in one-half one fashion, with a line drawn straight through our bodies. Most of the time, animals with radial symmetry move little or movement up and downward, like a jellyfish that propels itself through the water. Breakable stars, withal, move forrard, perpendicular to their torso axis — a skill commonly reserved for the bilaterally symmetrical.

Encephalon Like a Pigeon

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

When given a choice, pigeons volition push a button that gives them a big, rare payout rather than 1 that offers a modest reward at regular intervals. This questionable decision may stem from the surprise and excitement of the big reward, according to a study published in 2010 in the periodical Proceedings of the Royal Social club B. Homo gamblers may be similarly lured in by the idea of major loot, no matter how long the odds.
