What Are The Final Products Of Meiosis In Humans And Most Other Animals
7 Ways Animals Are Like Humans
Animals and Humans
Nosotros humans like to think of ourselves as a special agglomeration, but it turns out nosotros take plenty in common with other animals. Math? A monkey tin can practice it. Tool use? Hey, even birds have mastered that. Culture? Deplorable, folks — chimps have it, too.
Here's a list of some of the tiptop parallels between humans and our animal kin. You may be surprised at how like we are to fifty-fifty our distant relations.
Ears Similar a Katydid
Humans have circuitous ears to translate sound waves into mechanical vibrations our brains can process. And then, every bit information technology turns out, do katydids. According to research published November. xvi, 2012 in the journal Science, katydid ears are arranged very similarly to human ears, with eardrums, lever systems to amplify vibrations, and a fluid-filled vesicle where sensory cells expect to convey data to the nervous system. Katydid ears are a fleck simpler than ours, merely they can also hear far above the homo range.
Worlds Similar an Elephant
Humans practise reign supreme in the loonshit of language (as far as nosotros know), but fifty-fifty elephants tin effigy out how to brand the aforementioned sounds we exercise. According to researchers, an Asian elephant living in a S Korean zoo has learned to use its trunk and throat to mimic human words. The elephant can say "hullo," "good," "no," "sit downwards" and "lie down," all in Korean, of form.
The elephant doesn't appear to know what these words mean. Scientists recall he may have picked upwardly the sounds considering he was the only elephant at the zoo from when he was v to when he turned 12, leaving him to bond with humans instead.
The Facial Expressions of a Mouse
Do you make weird faces when yous're in pain? And then do mice. In 2010, researchers at McGill University and the University of British Columbia in Canada institute that mice subjected to moderate hurting "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 slumber-talk in whale song, according to French researchers who've recorded the marine mammals making the non-native sounds tardily at night. The v dolphins, which live in a marine park in France, have heard whale songs but in recordings played during the day around their aquarium. But 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 Water" it is not, but a home built by an octopus has the advantage of being mobile.
The veined octopus (Amphioctopus marginatus) tin can brand mobile shelters out of coconut shells. When the beast wants to move, all it has to do is stack the shells like bowls, grasp them with stiff legs, and waddle abroad along the body of water floor to a new location.
The Movements of a Brittle Star
It'd be hard to imagine an organism less like a human than a brittle star, a starfish-like brute that doesn't fifty-fifty accept a central nervous organization. And yet these five-armed wonders movement with coordination that mirrors human locomotion.
Brittle stars have radial symmetry, meaning their bodies tin can be split into matching halves by drawing imaginary lines through their arms and central axis. Humans and other mammals, in comparing, have bilateral symmetry: Yous can split us in half ane mode, with a line fatigued straight through our bodies. Most of the time, animals with radial symmetry movement piffling or move upwardly and down, like a jellyfish that propels itself through the water. Brittle stars, however, motility forward, perpendicular to their torso axis — a skill usually reserved for the bilaterally symmetrical.
Brain Like a Dove
Gamblers in Vegas have something in common with pigeons on the sidewalk, and it's not just a fascination with shiny objects. In fact, pigeons brand gambles just like humans, making choices that get out them with less money in the long run for the elusive hope of a large payout.
When given a selection, pigeons will push a button that gives them a big, rare payout rather than i 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 written report published in 2010 in the periodical Proceedings of the Royal Gild B. Human gamblers may be similarly lured in by the idea of major boodle, no matter how long the odds.
