Chapter 20, Problem 14TYK
Summary Introduction
To review:
Three discoveries or inventions that have changed how humans are affected by natural selection and discuss how each discovery influences survival or reproduction in our species.
Introduction:
Humans have evolved through generations and there were many examples, which support that human evolution is due to natural selection. But it was later found out that these traits are results of changes in genetic makeup of the organisms.

Students have asked these similar questions
Provide a scientific example of evolution and/or natural selection. You can use human and/or animal examples. Describe how the animal/species developed an advantage over time or what the evolutionary process was.
Are humans still evolving? Say YES or NO and then SUPPORT answer using knowledge of evolutionary processes.
Discuss whether changes to an organism's physical environment are likely to result in evolutionary change. Use examples to support your reasoning. Second, using at least two examples, explain how the process of evolution is revealed by the imperfections of living organisms
