A History of Humans - 655 Words

Humans are a complex organism. The theory of evolution suggests that we all came from a single ancestor and have evolved over millions of years to create our species that lives to this day. But what is evolution? Who did we all evolve from? What makes us different than this ancestor of ours? What is Evolution? Evolution is a process that results in heritable changes in a population spread over many generations. Scientist Charles Darwin believed that natural selection was one of the main reasons for evolution. He also believed that complex creatures come from simple ancestors that changed over a period of time. As random mutations occur within an organisms genetic code, the beneficial mutations are preserved because they helped survival. A mutation is the changing of the structure of a gene, resulting in a variant form that might be transmitted to future generations. A gene is a unit of heredity that is passed down from a parent to offspring and determines some characteristic of the offspring. Natural selection is the environment choosing which mutations of genes would be beneficial and which would lead to the extinction of that species. The beneficial mutations are passed on through genes from parent to their offsprings. Overtime, this process is what formed humans to be so complex. As the genes of humans randomly mutated and caused a variation of species, natural selection decided who will live on and who will die out. If there was a bad mutation, then the species wouldShow MoreRelatedHistory Of Human History1342 Words   |  6 PagesIt’s 2134 and it’s some of the darkest times in human history.
