Biology Essentials- Natural Selection Guided Viewing
1: Who was Charles Darwin? What is he famous for?
-He is a scientist the first one who gave us a mechanism that really explained how evolution worked
2: What is evolution?
- Any changes in the gen pool
3: What is the gene pool? What are alleles?
-is a combination of all the genes in a population, as in called alleles
3: What is natural selection? What does it mean to have high “fitness”?
-Live or Die depending on the appearance that you have, and if you have high fitness you are able to survive and pas your genes on
4: How do we get new characteristics in organisms?
-It happens through mutation, it is anything that was added to the DNA and changed as well as reproduction
5: How else do we get genetic variability (variety) in organisms?
-Reproduction
6: Explain the story of the Peppered Moth. How is this an example of natural selection?
-Theirs is two types one that is dark and one that is light and the light is homogeneous recessive and the darker is Homologous dominant, The lighter one has the ability to camouflage even more, So the theory here is that the light one was given that trait naturally and birds would be more likely to eat the darker moths than the light ones.
7: What is the equation for Hardy-Weinberg Equilibrium?
-P^2 + 2 PQ + Q^2= 1
8: What are adaptations?
-When the gene pool has changed and the organism around have adapted to that specific environment.
9: What is the best definition of natural selection? (explain.)
-it is Differential Reproductive Success where were each made a little bit different that allows us to survive and pass those high genes down through generations
