Natural Selection - Guided Viewing worksheet
1. Who was Charles Darwin? What is he famous for?
- Charles was an English naturalist and geologist. He's famous because he is the first mechanism that explains how evolution can occur.
2. What is evolution?
- Any changes to the gene pool.
3. What is the gene pool? What are alleles?
- A gene pool the combination of all the genes in a population, we call the different varieties alleles.
4. What is natural selection? What does it mean to have high "fitness"?
- Natural selection is weigher you live or die based on the appearance that you have. High fitness is when you are able to survive and pass your genes on.
5. How do we get new characteristics in organisms?
- Depending how much resistance you have. The ones that have high resistance are selected to continue and the ones that have a low resistance will die.
6. How else do we get genetic variability (variety) in organisms?
- Through mutation and reproduction through our offsprings and creating different types or organisms.
7. Explain the story of the Peppered Moth. How is this an example of natural selection?
- The Peppered Moth has two different varieties it has the dark and light physical characteristic. The light moth has a recessive trait and dark appearance homozygous dominate or heterozygous dominate. This is an example of natural selection because in the industrial revolution started making the environment darker , the light moths the ones with low fitness creating a change in the gene pool so evolution occurred.
8. What is the equation for Hardy-Weinberg Equilibrium?
- p^2 + 2pq + q^2 = 1
9. What are adaptations?
- Known as process. A process selected for.
10. What is the best definition of natural selection? (explain)
- Natural selection is differential reproductive succession, we are each made a little bit different if that allows us to survive and pass those genes on because of high fitness that will eventually lead to adaptations. Simply random changes selected by the environment.
