What is the difference between humans and other animals

Sometimes, when we do tests on animal behavior, we use tests that apply to animals like humans, and we expect animals to perform in a similar way if they have similar abilities.

For example, the mirror test is used to see if animals have awareness of themselves as the image that they see in a mirror. If a mark is placed on the animal, they should show signs of knowing that the mark is on their body.

But what if an animal doesn't have the best vision? Do we just say that, because they can't perform the test in that way, they wouldn't pass? Expecting all other animals to perform similarly to humans on tests can be problematic. This makes learning about some parts of animal behavior difficult. But, what we have learned is pretty exciting. As we keep learning more and more about animal behavior, we are continually surprised. Gunnison's prairie dogs seem to have a fairly complex language So when is this communication complex enough for us to call it a language?

Elephants have been found to communicate across miles of land through subsonic sound. And when researchers slow a hummingbird's chirp down, it seems the song may be as complex as a song from some other birds, though more studies need to be done to understand this.

Do we view animal "language" as limited just because we have trouble understanding it? This Caledonian crow is solving a water level problem. It adds small blocks into columns of water to raise the water level, allowing it access to food. The crow also had to realize that one column was too wide, so the limited blocks wouldn't raise the water enough. Caledonian crows can solve problems and build tools, and can solve multiple-step puzzles that require a plan.

Are these examples of difficult problems? Most animals have a smaller size of brain. Among exceptions, bottlenose dolphins have bigger brains than humans. It is 1. Interestingly, jellyfishes do not have any brain. The power of logical thinking and rationality make humans superior to other animals. Humans have the ability to think critically and act accordingly. Also, they can express our emotions happiness, sadness, excitement, etc.

Very few animals are capable of expressing their emotions. Also, they are not the same as that of humans. This is one of the most striking differences between humans and animals. While humans possess monogastric digestive systems, some animals have a ruminant digestive system. For example, sheep have a four-chambered stomach. However, their digestion is not as efficient as humans. Humans walk upright and on two legs. Therefore they are called bipedal.

Most animals walk on four legs, and they are called quadrupedal. Also, some animals have different kinds of locomotion. For example, crocodiles crawl on land. Humans are the only species on earth that has natural language processing ability.

Their voice system is different from animals. Also, they communicate through words. Most animals communicate with each other on a basic level. However, some birds like parrots and other animals can imitate humans and subsequently talk like them. Science News. Story Source: Materials provided by Stockholm University.
