There are many differences between humans and animals , although there are also similarities. We must think that many of the ancestor animals became extinct and the idea that there are so many similar characteristics is still being sought. Let’s see the differences.
We come from monkeys, as both humans and chimpanzees separated from our ancestor six million years ago. And the change was gradual because we stopped doing some of the things that they still do.
Similarities
We can say that some of the things that we have the most similar have to do with basic needs . So both spices eat, sleep, rest, most of us reproduce, and we defend ourselves and fight for what is ours.
Main differences
Among the differences that exist when it comes to analyzing humans and animals, we can highlight a series of essential points because there really are many.
Knowledge
Human beings acquire knowledge to achieve solutions . There are animals that can follow a similar pattern, because they also internalize knowledge but they do not finish providing solutions because their brain is less advanced.
Sociability
There are groups of animals that socialize with each other. But they are not able to communicate until the end . The social capabilities of humans are always superior.
Language
Animals make various sounds and some can copy the language of humans but without knowing what they repeat. It is the human who has the full ability to speak and this is unique to us.
In its physical characteristics
There are many physical differences because animals tend to have fur while people have hair .
On the other hand, humans walk upright , naturally and comfortably on two feet. But the animals walk on four or two legs and they must do it in a stretched way not straight up, this is very complicated to happen.
A higher brain
What is clear is that the human brain is much more advanced. For it is normally three or four times larger than the brain of the largest monkey.
Movements
They are also different because although we can run, we will not move as fast as it can according to what type of species. While others can fly something not achievable by humans. And hence many more differences are observed.
Evolution of the human being: stages
Human evolution is what the historical and progressive process of biological change of the human being is called . It began between five and seven million years ago, with the birth of the common ancestor between humans and chimpanzees. It should be noted that in prehistoric times some species that are currently extinct inhabited the planet Earth but that, according to the researchers, they presented many similarities on a physical, biological and behavioral level.
- Australopithecus: they were the first primates to walk upright. Due to climate change they were forced to start hunting, abandoning the vegetarian diet that they followed until then.
- Homo habilis: its origin dates back to two million years ago and its main characteristic is the ability to develop stone tools. In regards to its cranial capacity, it was 800 cubic centimeters. Currently, the cranial capacity of Homosapiens is 1,200 cubic centimeters on average for adults.
- Homo ergaster: it was the first human species to leave the African continent and conquer other territories. This made it the link between the two species to come: Homo antecessor in Europe and Homo erectus in the East.
- Homo antecessor: it was the first human link in Europe. Its stature was superior to that of its predecessors, although the brain was still small.
- Homo erectus: it became extinct 300,000 years ago and inhabited Asia. He made numerous stone tools, and also cooked food on fire. There were great changes in his muscles and in his digestive system, and he also developed an articulate language.
- Homo rhodesiensis: He was born in Africa and his cranial capacity ranged between 1,280 and 1,325 cubic centimeters. It is the direct ancestor of Homo sapiens.
- Homo sapiens: and finally Homo sapiens, the modern human.
Curiosities of the human being that will surprise you
The body of an adult human being has 206 bones . The longest of all is the femur, present in the upper part of both legs. Its length is equivalent to 26.74% of the person’s height, although the proportion may vary depending on the ethnic origin and gender of the person.
And which is the smallest? The tiny stapes , a small bone in the ear whose length ranges between 2.5 and 3 centimeters.
There is something very curious about the human being, and that is that he loses about 21 grams as soon as he dies . Scientists explain that when the heart stops beating, the body quickly deflates, expelling all the gases from the lungs and stomach.
