vii Ways Animals Are Like Humans

Animals and Humans

We humans like to think of ourselves as a special bunch, but information technology turns out we take plenty in common with other animals. Math? A monkey can do information technology. Tool use? Hey, fifty-fifty birds have mastered that. Culture? Lamentable, folks — chimps have information technology, too.

Hither'due south a list of some of the elevation parallels betwixt humans and our animal kin. You may exist surprised at how similar we are to fifty-fifty our distant relations.

Ears Like a Katydid

Humans have complex ears to translate sound waves into mechanical vibrations our brains tin process. So, every bit it turns out, do katydids. According to research published November. xvi, 2012 in the journal Science, katydid ears are arranged very similarly to homo ears, with eardrums, lever systems to amplify vibrations, and a fluid-filled vesicle where sensory cells look to convey data to the nervous system. Katydid ears are a chip simpler than ours, simply they can besides hear far higher up the man range.

Worlds Similar an Elephant

Humans practice reign supreme in the arena of language (as far as nosotros know), simply even elephants can figure out how to make the aforementioned sounds nosotros do. According to researchers, an Asian elephant living in a South Korean zoo has learned to utilise its trunk and pharynx to mimic human words. The elephant can say "hello," "skillful," "no," "sit down" and "lie down," all in Korean, of class.

The elephant doesn't appear to know what these words hateful. Scientists think he may have picked up the sounds because he was the simply elephant at the zoo from when he was 5 to when he turned 12, leaving him to bond with humans instead.

The Facial Expressions of a Mouse

Do yous make weird faces when y'all're in pain? So practise 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 past 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 belatedly at night. The five dolphins, which live in a marine park in France, have heard whale songs but in recordings played during the day effectually their aquarium. Just at night, the dolphins seem to mimic the recordings during remainder periods, a possible class of slumber-talking. And y'all idea 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 past an octopus has the advantage of being mobile.

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

The Movements of a Brittle Star

It'd be difficult to imagine an organism less similar a human than a brittle star, a starfish-like fauna that doesn't even have a fundamental nervous system. And yet these v-armed wonders move with coordination that mirrors homo locomotion.

Brittle stars have radial symmetry, pregnant their bodies tin be 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 half one manner, with a line drawn direct through our bodies. Most of the time, animals with radial symmetry move little or move upward and down, like a jellyfish that propels itself through the water. Breakable stars, however, movement forward, perpendicular to their body centrality — a skill usually reserved for the bilaterally symmetrical.

Gamblers in Vegas have something in mutual with pigeons on the sidewalk, and it's not simply a fascination with shiny objects. In fact, pigeons make gambles just 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 selection, pigeons will push a button that gives them a big, rare payout rather than one that offers a small advantage at regular intervals. This questionable determination may stem from the surprise and excitement of the big reward, co-ordinate to a study published in 2010 in the periodical Proceedings of the Imperial Social club B. Human being gamblers may exist similarly lured in by the idea of major loot, no matter how long the odds.
