Science has established that humans are a rational and intelligent species. In addition to the aliens, who are supposed to be ultra-intelligent, there is also the animal world. And which animals are the most remarkable?
The researchers intended a lot of time studying the animal species. The concept of intelligence existed in our collective culture since the beginning of our evolution. The philosophers Plato and Aristotle pondered this question, however, it was not until the 19th century that scientists began to quantitatively measure intelligence. This is how the most famous test came into force – intelligence quotient (IQ).
This studies a person's ability in various areas. And it is in the animal world adaptation (adjustment) very similar to intelligence. Animals develop many mechanisms, that help them survive in a certain environment. And these five animals do it very well.
Domestic pig
Scientists have been documenting since the 1990s behavior of pigs. In one survey, they are in the same room paired pigs that were trained to anticipate a negative or positive circumstance, with pigs that are naive and not ready to environmental changes. When the scientists measured their cortisol levels, matched this with their behavior, which confirmed the thesis that these animals have emotions, which is a sign of intelligence.
Butterfly
The shine on the wings of butterflies is not just beautiful, but also plays a role in development of 'green energy sources'. Morpho Didius butterfly wings contain structures that scatter blue light. These structures can now be installed on solar cells, because they should contribute to a more efficient distribution of energy.
A camel
Camels live in an environment that has forced them to develop many characteristics that allow them to survive. You can put your nose in completely clog. In this way they avoid that sand would enter their nostrils. They can do the same with theirs eyes. Their humps do not store water, but fat. But suddenly they can sleep 30 gallons of water.
It's gray
It's gray it is not only a beautiful animal, but also a smart one. Their wits should be on the level of a five-year-old child. Harvard scientists conducted an experiment to assess how gray detects the amount of juice in the container. They are in one container poured less juice, and poured more into the other. She had to distinguish the animal, which container has more juice.
Then they poured juice into one container, and the other was empty, but had a false bottom, which indicated that it contained juice. Despite the trick, the animals perceived, v which container has more juice. So they proved that their memory stores information, which influence their acceptance decision.
Gazelles (Dorcas)
Dorcas gazelles never drink water, as they get enough amount of water by feeding the plants. On this way they can survive in the environment in which they live.
