In his book, Darwin of the eighties, sought to explain the evolution of man as a process of natural selection. Darwin proposes four components of natural selection. First, he argues that characters within a population exhibit variations in appearance and conduct. This may be in terms of height, skin color or even body size. Darwin also talks about heritable traits, which are passed on from parents to offspring as opposed to traits powered by environmental conditions. His third component concerns population growth, which at times leads to mortality in cases where the resources cannot support the high population. The fourth component is derived from the third, in which Darwin argues that individuals with desirable traits will always survive in such an environment and give rise the next generation. This is known as natural selection, in which individuals struggle to survive and nature favors the strong. Based on this theory, human beings then have a high chance of evolving, powered by the advancement in technological innovations, which will enable them survive. Variations among individuals within a population are occasioned by genetic differences. Genes are the materials through which traits are inherited from parents to offspring. ...
Not all mutations are detrimental: a mutation in the brain of the Australopithecus enabled him to develop a larger brain and evolve into a hominid. Technological knowhow, however, has been seen to interfere with natural selection. Today, medics have come up with medicine to prolong the lives of mutants, thus encouraging the survival of weaklings which ultimately affects future generations. This means that individuals with desirable traits might mate with mutants and bring forth changes in the human race. This will lead to evolution, which will be occasioned by mutation. Consequently, future generations of human beings might not be able to survive. This not withstanding, not all mutations are negative. Some mutations may be advantageous to the human race. This perception has led to medical practitioners trying to come up with genetically modified human beings known as clones. These clones are designed to have all the positive attributes of their original humans and thus be more suitably adapted to live on earth. Human migration might also affect future evolution in terms of gene flow, which is a process of interbreeding between different populations of a given species (Mayr pp.55). When a person migrates from his original place of birth to go to another country, he is bound to start a family with the local people. This leads to the emergence of a new breed of people carrying the genes of both parents. An example of this is the era of the trans-Atlantic trade in which, many able bodied African men were shipped off to the United States to work as slaves. They later married the local women and gave rise to the African Americans. The latter were seen to have inherited most of

Inevitably, his views on alien life and space exploration exude in his film, “2001: A Space Odyssey” (“Space Odyssey”), which uses rich imagery and innovative visual effects to demonstrate the metaphysical and philosophical implications of outer space exploration and actual alien contact.
Evidence of the evolvement of Homo sapiens from Homo erectors has mainly been provided through analysis of human fossils that have shown that certain changes did occur in the brain and body size, diet, movement The changes in the millions of stone tools and footprints have also helped in the understanding of the evolution of Homo sapiens.
According to Heinrich, before agricultural evolution, humans spread throughout the globe, Therefore surviving in the different habitats did not only depend on the specific genetic configuration, but depended also on large body of cultural information transmitted across the groups, abilities, and other skills that no human could have comprehended alone.
Food is man’s foremost biological need and accessing it has top priority, in addition, studies show that transition from hunting and gathering to food production was a process as opposed to it being a sudden event. Man in all circumstances tries to adapt to the environment thus he has managed to procure food from surrounding resources
There is numerous and convincing evidence that living organisms have undergone the process of evolution spanning over a period of millions of years. The account of human evolution dates back to approximately 30 million years ago in North Africa, when the now expansive Sahara desert was an expanse of lush rain forests, and the region was inhabited by a species identified by historians as Aegyptopithecus.
These are the building blocks of deoxyribonucleic acid or DNA for short. X chromosomes represent nearly 5% of the total DNA in the females and around 2.5% in males. Every human being has usually a single pair of sex chromosomes in each of his

Today we can understand our existence and survival and know our self
The Homo class of hominin ancestors was particularly problematic in initial studies since it was at largely referred as the transition class to modern man.
