Evolution of Humans

In the beginning the anthropologists and evolutionists believe humans evolution from the primates, meaning that we walked in our four extremities, our teeth were different than now and another more differences. It is true all of that? Did we really evolution from the primates? Well some believe that, that theory is impossible and that is just said because people don't have an explanation of things, like for example how do we exist? From my point of view I am an biologist and I of course, believe in the evolution of the human. Not just it is a rational explanation of a how we have survived through the years, it also explains adaptation to the changes the world had suffer since the beginning. Scientific show through evidence that the physical and behavioral traits shares by all people originated from primates ancestors and evolved over a period of six million years.

It is said that one of the ability of humans, better known as Homo sapiens, of walking in two legs evolved over 4 million years ago, meaning that it was necessary to survive. It could be because the hotness of the ground was affecting the primates causing them further problems such as dehydration because of the closure to the floor. This could affect at great scale and cause deaths among them. Because humans are not that fast they'll be more time walking in the hotness of the ground, for a tiger he is more fast so walking in four paws does not affect him that much. Also walking in two legs gave the humans the ability of carrying food and their babies. Maybe it is not seen as an intelligent fact, but from the point of view of anthropologists it is a characteristic that makes the human more intelligent and more capable of success that other animals.

Because humans are primates, physically and genetically they show great similarities with other species of primates, the apes. The teeth also had evolution through time. Early humans, as I am going to call them, has different types of teeth for example the molars. The molars or the last teeth that appear in our mouths were to eat raw meat and the canines were to tear the meat apart. Today's day we do not need to use those teeth in the same manner because we are more sophisticated and do not need hunt like in the past. In conclusion, evolution is very necessary to survive and succeed in life. Adaptation has a purpose in life and with it it'll be possible to keep going on for a lot of years.
