    Human EvolutionIntroductionHuman evolution is the growth and adaptations of humans over the six million years we have lived on this earth. The reason we have adapted is to increase our chances of survival. There is plenty of scientific evidence that supports this concept of evolution, such as human fossils, natural selection, genetic evidence, and major developments in humans over the past six million years, such as bipedalism. This report will explain the concept of human evolution, provide solid scientific evidence to support the concept, and give examples for this theory. Explain the scientific concept The theory of human evolution is the basis of scientific evidence showing that humans have adapted significantly over time. I've been around. Human evolution has been so successful because of our ability to quickly adapt to the difficulties we encounter in order to survive. Paleoanthropology, the study of human evolution, is the most important scientific debate the world has ever known, because it is the key to how and why our bodies evolved from the Ardipithecus stage to what we are today (homo sapiens). An organism's genetic code can be changed when it is passed on to its offspring. Mutations can occur when this process occurs much like the hammerhead shark's head. These mutations can either thrive and create a better organism or destroy its occupant. Discuss the evidence for the theory There is a lot of evidence that supports the theory and explains a lot about the way we are. Human fossils have shown that many parts of our bodies adapted. The main ones being our skulls and spines. Our skulls changed due to the discovery of fire and cooked food, meaning we no longer needed large, strong jaws, so our jaws became smaller. A...... middle of paper...... a major advantage that started with a mutation in their DNA. (Mutations)Interesting Facts- Bipedalism is the ability to walk on two feet. This was a huge development in humans because it allowed us to have two free hands, which would have led to the making of tools. This has spiraled into a spiral of new advantages in our evolution and is certainly one of the reasons why Homo sapiens has survived so successfully. Humans were once threatened with extinction due to environmental catastrophe. The human population increased from about two million to about three thousand. According to the scientist Homo sapiens, humans are still evolving and are far from completing their evolutionary process. In fact, the human brain is thought to shrink due to the lack of extra mass, as the human brain becomes more efficient.ConclusionReferences
