EVOLUTION
How does Natural
Selection work?
Why makes certain individuals more able to survive?

7. Page 1 directions
Complete the Frayer chart for page 1 using the information on the following slides (links below).
What is evolution?
Why makes certain individuals more able to survive?
What is natural selection?
How does Natural Selection work?

8. The change in populations over time.
What is evolution?
The change in populations over time.

9. Insights into why only certain individuals survive…
Traits vary among populations; these traits are inherited
Breeding with others that had desirable traits produced offspring with these traits

10. What is natural selection?
Mechanism of change in populations over time

11. (Inside) On Bottom Flap pg. 2 draw:
Who is Darwin?
Who is Malthus?

12. Directions pg. 2
Complete the chart using the information for the following (links below)
Who is Darwin?
Darwin’s book.
Darwin’s hypothesis
Who is Malthus?
Thomas Malthus
How Malthus affected Darwin’s Ideas?

13. Who is Charles Darwin?
English scientist/naturalist whose ideas provide foundation for the theory of evolution by natural selection
Sailed on HMS Beagle for 5 years studying and collecting biological and fossil specimens

15. Major Ports of Call… Galapagos Islands
Location: Near equator, 1000km off west coast of S. America
What he studied: many species of animals and plants unique to the island, but are similar elsewhere
Major findings: Observations led to his consideration that species change over time

16. Darwin’s book…
1859, The Origin of Species
Detailed account on his ideas and theories that support evolution

17. Darwin’s Hypothesis…
Artificial Selection- breeding organism with specific traits in order to produce offspring with identical traits
There is force in nature that works like artificial selection

18. Thomas Malthus
Proposed idea that human populations grow faster than Earth’s food supply

19. How Malthus affected Darwin’s ideas…
Realized organisms struggle to compete in changing environments. Many types of competition exist:
Food and space
Escaping predators
Location of shelter

20. 2. Origins of Evolution

21. (Inside) On Top Flap pg. 3 draw:
BIOGENSIS
SPONTANEOUS GENERATION

22. Directions pg. 3
Complete the Venn diagram on pg. 3 using the following information. be sure to follow directions.

Spontaneous Generation
Biogenesis

23. Spontaneous Generation
Theory states that non-living matter produces life
Disproved by Redi’s Experiment
“Life does not just appear, it comes from other living things”

24. Biogenesis Theory that living things come from other living things
Proven by Pasteur’s experiment

25. (Inside) On Bottom Flap pg. 4 :
Paste/Tape the following pictures

26. 3. Natural Selection

27. (Inside) On Top Flap pg. 5 draw:
What is Natural Selection?
How does it occur?
NATURAL SELECTION
Picture
What are the types of Natural Selection?

28. Directions pg. 5
Complete “Natural Selection” Frayer chart using the following information using the links below:
What is Natural Selection?
How does it occur?
What are the types of Natural Selection?
Picture (put picture on pg. 6 of your booklet.)

29. Natural Selection What is it?
Change in an allele over a period of time
How does it occur?
Occurs in populations! Evolution can not occur in a single individual

30. Types of Natural Selection are:
Stabilizing
Directional
Disruptive
Picture:

31. (Inside) On Bottom Flap pg 6
(Inside) On Bottom Flap pg 6. write: Glue in the following picture & Label the following:
A) mode of natural selection in which a single phenotype is favored, causing the allele frequency to continuously shift in one direction
B) Mode of natural selection in which genetic diversity decreases as the population stabilizes, selects against extreme values of the character and favors the intermediate variants
C) extreme values for a trait are favored; the variance of the trait increases and the population is divided into two distinct groups

32. 4. Influences of Evolution

33. (Inside) On Top Flap pg. 7 write: Glue in the following picture & Label the following:
Genetic Equilibrium
Defined as the frequency of alleles that remains the same over generations
Evolution only occurs when alleles are not in equilibrium
Label the picture that shows “genetic equilibrium”
Mutations
Any change in DNA
Causing individuals in a population to express a new phenotype

34. (Inside) On Bottom Flap pg
(Inside) On Bottom Flap pg. 8 write: Glue in the following picture & Label the following:
Gene Flow
also called migration
addition of genes into a population
alters allelic frequencies
Genetic Drift
random events remove genes from a population
gene frequencies in a population change

35. 5. Patterns of Evolution & Speciation

36. (Inside) On Top Flap pg. 9 write: Glue in the following picture & Label the following:
Divergent Evolution
Species that evolve to be different even though they come from a common ancestor
Convergent Evolution
Species that evolve to be similar to each other
For example: they have similar structures

37. (Inside) On Bottom Flap pg
(Inside) On Bottom Flap pg. 10 write: Glue in the following picture & Label the following:
Speciation
a lineage-splitting event that produces two or more separate species

38. 6. Evidences of Evolution

39. (Inside) On Top Flap pg. 11 write:
Evidences of Evolution
Adaptations- structural and physiological
Fossil Evidence
Anatomical Evidence
Embryology
Biochemistry
Why?
Variation that aids an organisms chances of survival in its environment
Develop in a species over many generations

40. (Inside) On Bottom of Flap pg. 12 write:
Structural Adaptations
Teeth and Claws
Protect against predators
Mimicry
Enables one species to resemble another
Camouflage
Enables species to blend with surroundings
Physiological Adaptations
What are they?
Changes in organism’s metabolic processes
Example:
After years of exposure to specific pesticides, insects and weeds have become resistant

41. (Inside) On Top Flap pg. 13 write: (more to write on next slide)
Anatomical Evidence
Homologous Structures- common evolutionary origin
2. Analogous Structures- no common origin, but similar in function
Fossil Evidence
Indirect source
Provide record of early life
As record becomes more complete, the sequence of evolution is clearer

42. (Inside) pg. 13 continue write:
Embryological Evidence
Similarities in development before birth
Anatomical Evidence
3. Vestigial- body structure in present day organism that no longer serves original purpose
