Students have asked these similar questions
what is evolution and its importance? How would you explain it?
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?
Define evolution:
What is decent with modification?
Use Mosquitoes and DDT to explain natural
selection.
What does the term fitness mean in the
context of evolution?

If you answer yes, explain why this is the case.

Natural selection is the main mechanism driving this change. Yet, for life on Earth, there are many unifying characteristics that we all share that form an unbroken bond between all organisms. Energy and Matter, heredity and the genetic code, interrelationships among organisms. These are the “Big Ideas” that bind us all. Each of the following are contributed toward the Living Systems of today: Biochemistry and the “Big 4 Macromolecules” The cellular nature of life Metabolism and energy (Photosynthesis and respiration) Heredity and the universality of DNA (gene control too) Evolutionary mechanisms Describe how the vast variety of species of living things came to be, and still tie in all of the similarities they share. How does each of ALL the mentioned above help shape the Unity and Diversity of Life on Earth? Include sources if applicable.aarrow_forward
