Evolution Unit Test 2015 Ch 16-19, non-honors/14-17 honors
Students should be able to…
1. Describe what the Theory of Evolution states.
2. Name the person who developed this theory & describe how he developed it.
3. Define the following and give an example of each.
Species, Population, and
Natural selection
4. Describe what the Hardy-Weinberg (H-W) law states and list the five
conditions.
5. Determine allele frequencies. Honors only.
6. Describe how fossils and strata provide evidence for the theory of
evolution
7. Determine the age of rocks and fossils using radioactive dating.
8. Describe an example of homologous structures and vestigial structures.
Explain how they provide evidence of evolution.
9. Explain how development and molecules provide evidence of evolution.
10. Interpret and develop a cladogram.
11. List the traits of biota.
12. Classify organisms based on the traits of each Kingdom.
Who am I?
Similarities in Early
Development
• If populations accumulate
change over time organisms…
• Then organisms should
develop similarily if they share
a common ancestor.
Who am I?
Who am I?
Who am I?
Are they similar
to us?????

Molecular Evidence
 IF
CHANGE
accumulates in
a
POPULATION
over TIME…
 THEN
organisms
with close
common
ancestors should
share more
molecules, such
as DNA.

Summary of Darwin’s Theory

Individuals in nature differ from one
another

Organisms in nature produce more offspring
than can survive, and many of those who do
not survive do not reproduce.
Summary of Darwin’s Theory

Because more organisms are produce than
can survive, each species must struggle for
resources

Each organism is unique, each has
advantages and disadvantages in the
struggle for existence
Summary (cont.)

Individuals best suited for the environment
survive and reproduce most successful

Populations within species change over time
Summary (cont.)

Species alive today descended with modification
from populations that lived in the past

All organisms on earth are united into a single
family tree of life by common descent
Who’s the strongest?
