Everybody has surely wondered what goes on in an animal's mind. Do they can feel emotions, if they can ever be happy or sad? And moreover, how alike is their thinking to our. Would we get along with animals if the language issue would be crossed out? There have been many studies that were trying to determine every little detail animal life could keep secret, including the debatable subject if and how animals think.
A couple of years ago, there were reported over 1,3 million species of animals all over the planet. Moreover, almost 62,500 of these species present a backbone. Life on Earth is made up pretty much of the same system unit. Evidently, there are still many differences that make us work a little to find out more about the questions life on this planet rises.
There are basic feelings that are common to pretty much all of us; the sensation of hunger and thirst, fear, safety, cold and heat, pain and pleasure. As you might have expected, the way in which we all react can be extremely different, thing that might make things harder to understand for humans. For example, there is a type of crabs that, when feeling pain, they get out of their shell. Ironically, those with better shells take more time to evacuate it than the ones with poor quality shells. From this behaviour, scientists have concluded that even though they aren't as aware of where the pain came from as a human would be, hermit crabs usually hand onto these more valuable things.
