Biology Essentials- Natural Selection Guided Viewing
1: Who was Charles Darwin? What is he famous for?
Charles Darwin was an English naturalist and geologist, best known for his contributions to evolutionary theory. He was a naturalist and an evolutionist who believed that people were descendants of common ancestors.
2: What is evolution?
Evolution is the biological model for the history of life on Earth.
3: What is the gene pool?
The gene pool is the set of all genes, or genetic information, in any population, usually of a particular species.
What are alleles?
Alleles are the different types of genetic material that code for a specific protein - or gene.
3: What is natural selection?
Natural selection is the gradual natural process by which biological traits become either more or less common in a population as a function of the effect of inherited traits on the differential reproductive success of organisms interacting with their environment.
What does it mean to have high “fitness”?
Have high fitness is means you are able to survive and pass genes on.
4: How do we get new characteristics in organisms?
To get new characteristic in organisms is mutation.
5: How else do we get genetic variability (variety) in organisms?
To get genetic variability (variety) in organisms is reproduction.
6: Explain the story of the Peppered Moth. The peppered moth story is simple, easy to illustrate, and makes intuitive sense. It is a common moth that is used as a common example of observable natural selection.
How is this an example of natural selection?
Light is a example of natural selection because they were able to camouflage and survive, from there it having a higher fitness.
7: What is the equation for Hardy-Weinberg Equilibrium?
The equation for Hardy-Weinberg Equilibrium is (p² + 2pq + q² = 1).
8: What are adaptations?
Adaptations are the inherited traits of an organism that enhance their survival and reproduction in specific environments.
9: What is the best definition of natural selection? (explain.)
The best definition of natural selection is survival and reproduction of the organisms that are genetically best adapted to the environment.
