It has been clear to some researchers that humans are still evolving. Within the last 5,000 to 15,000 years, studies have shown that the genes in many regions of human genome have been shaped by natural selection. Many paleontologists are trying to show that evolution is still currently in the process of changing gene frequencies over time, which means that over generations, there will be changes in the gene pool, and humans experiences those changes as much …showed first 75 words of 513 total…

These modifications are the key to the evolution of new species, or as Darwin would call it "survival of the fittest". So, as humans are still evolving, our environment is obviously changing as well. Whether it is global changes or land movement, natural selection is acting upon humans to live for thousands of more years.
