Origin of Humans.
Have you ever wondered, how we humans have come into being what we are today? We have in our power the ability to explore our environment and also the potential to annihilate most living organisms. We posses the talent to organise and feel comparison, yet wage endless wars.
Let’s start at the beginning. It has been recorded that twenty million years ago, a creature called Proconsul lived in the trees and fed off fruit and leaves. There were other varying species that varied in size and they clambered through the safety of the trees, moving from one branch of a tree to the next. When on the ground these species walked with open flat hands and their limbs were all the same size. Fossils suggest they were non aggressive and this may have helped with their capability to developing reason.
Ten million years ago, the temperature became extremely cold and trees became scarce thus forcing the Proconsul to move on to the ground and to move about on all four limbs. This state of affairs was to change in about four million years when Ardipithecus came on the scene. Ardipithecus possessed hands that were between human and ape, plus they walked on two legs and had arms that were knee height. The terrain at that time became a boundless savannah and the new home for Ardipithecus who evidenced the physical traits of both apes and humans.
As each species appeared there is factual evidence of an increase in brain size and the aesthetics altering, such as a protruding muzzle receding. Over time the forehead and eyes of developing species became more recognizable to modern humans.
The progress of evolution is not in a straight line. So at times there are various lines of different development. At about two million years go Homo Habilis has the first claim to human creative development. It is possible they may have had knowledge of making fire and have historically gained the nickname of handymen, possibly because of their useful ability to make tools and fashion wood.
At about one point five million years ago, a new development appeared in that of the Homo Augusta. A new era of man turned hunter as he used spears and other weapons on all forms of life. He also set about exploring his environment.
Homo heidelbergensis possessed the same brain size as modern man. They buried their dead and created art. They used their reason to build shelters and protect themselves. They lived about two hundred thousand to six hundred thousand years ago.
The most recent example of competing species of humans are represented by the Neanderthals. They lived about forty thousand years ago, and it is not clear what happened to them. Their DNA is evidence that Neanderthals and humans interbred and there are several branches of human like species such as the Denisovan which too could have bred with Neanderthals and humans.
Another group of early humans is the Homo floresiensis nicknamed the hobbit as they lived on an island about fifty thousand years ago. The hobbit refers to the fact they would have been fully grown at three foot seven inches tall.
One fascinating thought, is there another hominid that could have bred with early humans? Perhaps one or maybe more, but of which we have no fossil records to evidence that it took place? The mechanism of evolution is adaption for survival. If there is no need for change, then a species will stay generally the same. Individually there is constant variation and a competitor for survival will favour a more advantageous development and we know from both science and history that over long periods of time the individuals with a better rate of survival will dictate the course of evolution for that species.
