Human EvolutionIntroductionHuman evolution is the growth and adaptation of humans over the six million years we have been on this earth. The reason we have adapted is to increase the chances of our survival. There is a lot of scientific evidence that supports this concept of evolution such as human fossils, natural selection, genetic evidence, and important developments in humans over the six million years such as bipedalism. This report will explain the concept of human evolution, provide solid scientific evidence to support the concept, and provide examples of this theory. Explain the scientific concept The theory of human evolution is the basis of scientific evidence showing that humans have adapted greatly 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 discussion the world has ever known because it is the key to understanding how and why our bodies transformed from the Ardipithecus stage to what we are now (homo sapiens) . The genetic code of an organism can be changed when it is passed on to offspring. Mutations can occur when this process occurs much like the hammerhead shark's head. These mutations can thrive and create a better organism or destroy its occupant. Discuss the evidence to support the theory There is a lot of evidence to support the theory which explains a lot about how we are the way we are. Human fossils have shown that many parts of our body have adapted. The main ones are our skulls and our dorsal spines. Our skulls have changed due to the discovery of fire and cooked food, meaning we no longer need large, strong jaws, so our jaws have become smaller. A... middle of paper... a great advantage that started as a mutation in their DNA. (Mutations) Interesting Facts - Bipedalism is the ability to walk on two feet. It was a huge development for humans as it allowed us to have two free hands, which is believed to be what led to the making of tools. This has spiraled into new advantages in our evolution and is certainly one of the reasons why Homo sapiens has survived so successfully. - Humans were once at risk of extinction due to an environmental disaster. The human population has decreased from about two million to about three thousand. - According to the scientist Homo sapiens, humans are still evolving and are nowhere near the end of our evolutionary process. In fact it is believed that the human brain is shrinking due to the lack of need for extra mass because the human brain is becoming more efficient. Conclusion References
