How Good Is Human Vision Compared To Other Animals

seven Ways Animals Are Like Humans

Animals and Humans

We humans like to think of ourselves as a special bunch, but it turns out nosotros have enough in common with other animals. Math? A monkey can exercise it. Tool use? Hey, even birds accept mastered that. Culture? Sorry, folks — chimps accept it, as well.

Here's a list of some of the acme parallels betwixt humans and our beast kin. You may be surprised at how similar we are to even our distant relations.

Ears Like a Katydid

Humans take complex ears to translate sound waves into mechanical vibrations our brains can process. So, as it turns out, do katydids. According to research published Nov. 16, 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 wait to convey information to the nervous organization. Katydid ears are a bit simpler than ours, just they can also hear far in a higher place the man range.

Worlds Similar an Elephant

Humans do reign supreme in the arena of linguistic communication (as far equally we know), but fifty-fifty elephants tin can figure out how to make the same sounds we do. Co-ordinate to researchers, an Asian elephant living in a South Korean zoo has learned to utilize its torso and throat to mimic homo words. The elephant can say "hello," "good," "no," "sit down" and "prevarication downward," all in Korean, of course.

The elephant doesn't appear to know what these words mean. Scientists retrieve he may have picked upward the sounds because he was the but 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 you're in pain? And then do mice. In 2010, researchers at McGill University and the Academy of British Columbia in Canada plant that mice subjected to moderate pain "grimace," simply 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

Dolphins may sleep-talk in whale song, co-ordinate to French researchers who've recorded the marine mammals making the not-native sounds late at night. The five dolphins, which live in a marine park in French republic, accept heard whale songs merely in recordings played during the day effectually their aquarium. But at dark, the dolphins seem to mimic the recordings during residuum periods, a possible grade 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, simply 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 move, all it has to practice is stack the shells like bowls, grasp them with potent legs, and waddle away along the ocean floor to a new location.

The Movements of a Breakable Star

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

It'd exist hard to imagine an organism less like a human than a brittle star, a starfish-similar creature that doesn't even have a fundamental nervous organization. And however these five-armed wonders move with coordination that mirrors man locomotion.

Brittle stars have radial symmetry, meaning their bodies can be split into matching halves by cartoon imaginary lines through their artillery and central axis. Humans and other mammals, in comparison, have bilateral symmetry: You can carve up us in half one way, with a line drawn directly through our bodies. Most of the time, animals with radial symmetry move lilliputian or move upward and downward, like a jellyfish that propels itself through the water. Brittle stars, however, motility forward, perpendicular to their body axis — a skill normally reserved for the bilaterally symmetrical.

Encephalon Like a Dove

Gamblers in Vegas have something in common with pigeons on the sidewalk, and information technology's not just a fascination with shiny objects. In fact, pigeons brand gambles just 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 option, pigeons will push a push 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, co-ordinate to a study published in 2010 in the journal Proceedings of the Regal Society B. Human gamblers may be similarly lured in by the idea of major loot, no matter how long the odds.
