In a strictly scientific and general sense, intelligence is defined as the innate capacity that human beings have to analyze and acquire a certain degree of learning throughout their lives. Despite this, a meaning regarding what intelligence really is has not yet been accepted as such. This term comes from the Latin word "intellegere", being "inte" between and "llegere" read or choose.
Intelligence, like other similar topics, has been debated for thousands of years. This is because it is not known exactly what it is and how it affects man. Of course, it is considered an essential element for the acquisition of knowledge, the analysis of the environment and the adaptation to different situations. In addition, it has also been believed that this ability can be measured by making testing a subject anyone, with so- called " IQ test " exam (IQ), developed under the belief that intelligence can be agility to solve problems quickly.
There are, in the same way, different types of intelligences among which stand out: linguistic intelligence (understanding and proper use of words), musical intelligence (understanding and recreation of complex sounds), logical- mathematical intelligence (solving complex problems is the predominant characteristic), spatial intelligence (ability to distinguish relationships between shapes and colors), body-kinesthetic intelligence (controlling and transmitting feelings through the body), interpersonal intelligence (understanding the feelings and attitudes of others) and intrapersonal intelligence (self-understanding).
Also, another theory proposed by the psychologist Robert J. Sternberg, dictates three types of possible intelligence, these being the component-analytic, the experiential-creative and the contextual-practical. Despite all the theories and hypotheses of how intelligence works, some scientists support the belief that intelligence has developed in all beings for thousands of years, due to the routine changes that our ancestors suffered in their diets and social interactions.
