Human evolution and challenges

in this fury to resolve our problems we have unknowingly tackled various other problems which we never wanted nor expected to exist but this subtle approach supported by a long passage of time has led to a revolutionary evolution of the species. We have become the most superior species on the planet . Human evolution from its first separation from the last common ancestor of humans and chimpanzee is characterized by a number of developmentalphysiological, behavioral and of course the most crucial mental changes the 

                                                                            


    our hard work and ability to work towards problems has bore some valuable fruits for us in the form of a united empire as we talk about the 21st century, The evolution of the skin pattern is also a very interesting story. Dark skin is thought to have evolved in the first fur-less humans in Africa, to protect against the ultraviolet radiation in intense direct sunlight. Humans living in higher latitudes, went this line of reasoning, would be exposed to less UV radiation, and thus it has influenced the skin type and facial structure which we usually experience and we are very well aware of.

                                                


Moreover, living in communities is central to our species’ success. large groups became essential to survival because they offer assistance, to offset the difficulties of giving birth to big-brained babies and caring for them through a long infancy. Modern humans are also the longest-living primate species: three generations can overlap in time. Individuals stay ‘useful’ beyond their reproductive period by taking care of their children’s offspring and even unrelated infants, by the time we started slowly developing towards critical thought culture which revolutionized our existence .
