What Animal Is Most Genetically Similar To Humans
7 Means Animals Are Similar Humans
Animals and Humans
We humans like to think of ourselves as a special bunch, only it turns out we take enough in common with other animals. Math? A monkey can do it. Tool use? Hey, even birds have mastered that. Culture? Sad, folks — chimps accept it, also.
Hither's a list of some of the top parallels between humans and our animal kin. You may be surprised at how similar we are to even our afar relations.
Ears Similar a Katydid
Humans have complex ears to interpret sound waves into mechanical vibrations our brains can process. So, every bit it turns out, do katydids. According to research published Nov. 16, 2012 in the periodical 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 wait to convey information to the nervous system. Katydid ears are a fleck simpler than ours, only they tin too hear far to a higher place the human range.
Worlds Like an Elephant
Humans do reign supreme in the loonshit of linguistic communication (as far as we know), just even elephants can effigy out how to brand the same sounds we do. Co-ordinate to researchers, an Asian elephant living in a South Korean zoo has learned to use its torso and throat to mimic human words. The elephant can say "how-do-you-do," "good," "no," "sit down down" and "lie down," all in Korean, of form.
The elephant doesn't announced to know what these words hateful. Scientists think he may have picked up 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
Practice yous 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 hurting "grimace," just like humans. The researchers said the results could be used to eliminate unnecessary suffering for lab animals past letting researchers know when something hurts the rodents.
The Sleep-Talk of a Dolphin
Dolphins may sleep-talk in whale song, co-ordinate to French researchers who've recorded the marine mammals making the non-native sounds tardily at dark. The v dolphins, which live in a marine park in France, take heard whale songs simply in recordings played during the twenty-four hour period around their aquarium. But at night, the dolphins seem to mimic the recordings during rest periods, a possible grade of sleep-talking. And you idea your nocturnal mumblings were weird.
The House-Building Skill of an Octopus
Okay, Frank Lloyd Wright's "Falling Water" information technology is not, but a abode built by an octopus has the advantage of being mobile.
The veined octopus (Amphioctopus marginatus) can make mobile shelters out of kokosnoot shells. When the brute wants to move, all it has to do is stack the shells like bowls, grasp them with strong legs, and waddle away along the ocean floor to a new location.
The Movements of a Brittle Star
It'd exist hard to imagine an organism less like a human than a brittle star, a starfish-like brute that doesn't even have a cardinal nervous organization. And yet these 5-armed wonders movement with coordination that mirrors human locomotion.
Brittle stars have radial symmetry, meaning their bodies can be carve up into matching halves by drawing imaginary lines through their arms and cardinal axis. Humans and other mammals, in comparison, have bilateral symmetry: You can split us in half 1 way, with a line drawn straight through our bodies. About of the time, animals with radial symmetry move piffling or move up and down, like a jellyfish that propels itself through the water. Brittle stars, nonetheless, move forward, perpendicular to their body axis — a skill usually reserved for the bilaterally symmetrical.
Encephalon Like a Pigeon
Gamblers in Vegas accept something in common with pigeons on the sidewalk, and it'due south non just a fascination with shiny objects. In fact, pigeons brand gambles just like humans, making choices that leave them with less money in the long run for the elusive hope of a big payout.
When given a choice, pigeons volition button a push that gives them a big, rare payout rather than one that offers a small reward at regular intervals. This questionable conclusion may stem from the surprise and excitement of the large advantage, co-ordinate to a report published in 2010 in the journal Proceedings of the Royal Society B. Human gamblers may be similarly lured in by the idea of major boodle, no matter how long the odds.
