Human Evolution
  Human evolution is the order of nature,therefore it belongs the category of (science),rather than a (paranormal) one that is beyond the range of scientific explanation.
  Human evolution used to be a process of gradual change that took place over many generations,during which (primitives) changed some of their physical characteristics.
  First of all,the earliest primitives called troglodytes were evolved from the anthropoids.They experienced some developmental stages.They stepped down the trees where they used to live and learned to walk upright around to hunt what they lived on,having no fixed abode.In order to survive the hostile environment,they moved into grottoes,where they could be in a state of (euphoria).groups of organisms were (stimulated) by the survivable activities and at last changed with passage of time,mainly as a result of natural selection.After a long period,human being got to be perfect and complete their evolutionary process,so that the descendants differ morphologically and physiologically from their ancestors.
  Found a (conjecture) on archaeological studies,human evolution has experienced a far-flung developmental stage,some of which are still doubts and suspicions and remain to be seen by archaeologists.
