is defined as human being to man, an animal that belongs to the family of homo sapiens . While it is common to define ourselves at the generic level as mens , this term can cause some confusion as it also refers to the male sex.
Historians tell that, in the prehistory , the gender homo It was composed of several species. However, since the homo neanderthalensis it became extinct (a fact that, approximately, took place 25 thousand years ago) and the earth disappeared homo floresiensis (extinction that happened about 12 thousand years ago), the only species that subsists from this clan is that of homo sapiens.
Man is the result of an evolution of primates known as hominoids . Its original development was in the African continent and the genre later expanded throughout the rest of the world.
The human being supposes the highest level of complexity reached by the evolutionary scale. He brain It has a great development and allows you to specify many rational activities and develop abstract, creative and other thinking. After over three years of age, the symbolic prevails in human thought.
It should be noted that humans appear among the animals with the longest multicellular characteristics of today, reaching over 100 years of age in certain cases. This circumstance has varied over the years since, in the first centuries of this era, the life expectancy of human beings was barely approaching 25 years.
In addition to these hallmarks of the human being we can establish that it has others that define it completely and that differentiate it from the rest of living beings that exist on the Planet. Among those are the following:
From an anatomical and biological point of view, it should be stressed that it has the so-called opposable thumbs thanks to which it is easier to be able to carry out the use of various instruments, which has a great plasticity of movements and that has a great variety in what is your external physiognomy. That is, this last aspect means that there is a palpable difference between many human beings, whether men or women, in terms of height, for example.
In the same way, it should not be overlooked that in terms of sexuality, not only does copulation take place for simple pleasure, and not only as a means of reproduction, but it is one of the few living beings that performs the same face to face.
In addition to all of the above, it should also be noted that in food, the human being is characterized by a very complete diet that includes both vegetables and meat. Specifically, for you to enjoy great health you must eat all those foods that include vitamins, proteins, minerals, carbohydrates and also lipids.
At the cerebral and mental level, we must not overlook the fact that it is the living being that achieves greater evolution.
Another peculiarity of the human being is that it is the only species that is aware of its finitude: that is, man knows that at some point he will die . The human being also believes in the existence of soul or similar entities that transcend the bodily experience.
