SBI 3U UNIT REVIEW
UNIT #2 – EVOLUTION
Introduction to Evolution:
1. What is evolution?
2. Explain how various people shaped Darwin’s life and his views on evolution
by Natural Selection and how their ideas laid the groundwork for Darwin
(Captain Fitzroy, Cuvier, Hutton, Lamarck).
Darwin’s Voyage
3. Know the details surrounding Darwin’s time on the HMS Beagle (dates,
destinations).
4. Know the observations and inferences Darwin had while on his voyage
(what did he do with specimens? Homologous, analogous, vestigial
features, know examples!!!)
Natural Selection
5. Be able to explain and support the theory of Evolution by Natural Selection.
Microevolution
6. What is microevolution?
7. Know and understand the difference between an allele, a genotype, and a
phenotype, and be able to give examples.
8. Know and understand the difference between dominant and recessive genes,
as well as the difference between homozygous and heterozygous genes.
The Hardy-Weinberg Principle
9. Know and understand the two parts to the Hardy-Weinberg principle. What
does each symbol represent (p, q, p2, pq, q2)?
10.Know how to solve problems using the Hardy-Weinberg principle.
Understand how to determine the frequency of alleles and genotypes of a
given population.
Patterns of Selection
11.Know and understand various patterns of selection (genetic drift, gene flow,
bottleneck effect)
12.Explain the various types of selection (stabilizing, directional, disruptive,
and sexual). Use examples to describe how evolution occurs over
generations.
Macroevolution & Speciation
13.What is macroevolution?
14.What is speciation?
15.Describe the various modes of speciation (allopatric, sympatric, parapatric).
Use examples.
16.Know and understand the two patterns of descent. Be able to give examples.
