Natural selection allows certain species to survive. The organisms that survive are those best adapted to their environment. Does natural selection make organisms more complex and perfect?
In your body, you have systems (digestive system, circulatory system, etc.). Each system is made up of organs. Each organ is made up of tissues. Each tissue is made up of cells. Each cell is made up of chemicals. What characteristic of life is being demonstrated by all this?
Group of answer choices
development
natural selection
evolution
irritability
high complexity
The concepts of natural selection and evolution are central to how most biologists understand and interpret the world, and yet the theory of evolution is contrary to the beliefs of many religious groups. Why do you think this theory is so important to science and so strongly opposed by others? What evidence would be required to convince opponents of evolution?
