Speciation


Changes in the gene pool of a population could
result in the evolution of a new species!
MACROEVOLUTION: refers to the appearance
of new species over time
Okapi
Giraffe
How Speciation Occurs

Geographic Isolation:
- occurs when a physical barrier divides a
population

EX – changes in sea level, building a road
How Speciation Occurs

Reproductive Isolation
- occurs when formerly interbreeding organisms can
no longer mate

EX – different genes, behavioral differences, etc.
Drill #8

4/9/2014
Speciation can occur in two ways. List the two
ways and give an example of each.
SWBAT

List and describe the five patterns of
evolution and give examples of each.

Patterns of Evolution
Patterns of Evolution
A.
Gradualism
Slow, constant, and
consistent process
Can not see in your
lifetime
Slight variations within
a population
B. Punctuated
equilibrium
Occurs in bursts;
Periods of very little change
followed by a rapid change
Mutations
Geographic isolation
Which type of evolution did the moth
lab show? Explain.
C. Divergent Evolution (Adaptive Radiation)
When a single species evolves into several different forms that
live in different ways
EX. Hawaiian honeycreepers
D. Convergent Evolution (analogous
structures)

Distantly related organisms evolve similar traits
due to their habitats
 Aardvark, anteater, echidna, and armadillo
 Butterfly wing , bat wing, and bird wing
Which type of evolution did the beak
lab show? Explain.
E.
Coevolution

When two species
evolve in response to
changes in each other
 flowers and bees
 herbivores and plants
 Predators/prey
Explain how the following cartoon shows
coevolution.
Evolution Today
Antibiotic resistance in bacteria
Since bacteria is always evolving and mutating,
some random mutation occurs that will protect
the bacterium against drugs causing them to
become resistant
Pesticide resistance in insects
A random mutation in insects protects them
from pesticides and will eventually cause them
to become pesticide resistant
Drill #10

evolution?
SWBAT




Examine the results of chromatography in order to

and coyotes)
Explain why classification of organisms important.
Use classification to determine relationships among
organisms?

SWBAT:

Use and create a dichotomous key in order to
classify and identify organisms.
Dichotomous Key



Tool used to identify organisms.
It is an organized set of couplets of mutually
exclusive characteristics of biological organisms.
The characteristics of an unknown organism are
compared against an appropriate dichotomous key.
