10
What did Darwin call Natural Selection
11
Survival of the Fittest
12
The process where the breeder selects the best trait is called?
13
Artificial Selection
14
What is the name of the book that Darwin wrote?
15
The Origin of Species
16
Hutton & Lylle both said what about the formation of the earth?
17
The earth is millions of years old/the earth was formed by geologic forces
18
The 2 guys that came up with a mathematical equation that can predict allele frequencies?
19
Hardy & Weinberg
20
All of the genes in a population is called?
21
Gene Pool
22
Name 2 sources of genetic variation.
23
Mutations Crossover (Gene Shuffling)
24
Any organ that is reduced in function that may have been used by an ancestor?
25
Vestigial Organ
26
Body structures that are similar in structure and function?
27
Homologous Structures
28
Body structures that are similar in function but different in structure are called?
29
Analogous Structures
30
A trait controlled by more than one gene is called?
31
Polygenic Trait
32
A random change in allele frequencies over the generations is called?
33
Genetic Drift
34
When allele frequencies remain constant it is called?
35
Genetic Equalibrium
36
What occurs when allele frequencies in a group of migrating individuals are by chance not the same as that of the original population?
37
Founder Effect
38
What effect can happen when a population’s numbers undergoes a drastic decrease?
39
Bottleneck Effect
40
Where individuals with favorable traits survive & pass on those traits to their offspring?
41
Natural Selection
42
When natural selection favors one extreme phenotype or the other.
43
Directional selection
44
When natural selection doesn’t favor either extreme phenotype.
45
Stabilizing selection
46
When natural selection favors both extreme phenotypes.
47
Disruptive selection
48
What are the 5 conditions to maintain genetic equilibrium
49
1.Must be random mating 2.Must have a large pop. Size 3.No movement of genes 4.No mutations 5.No Natural selection
50
The evolution of a new species
51
Speciation
52
When 2 populations become separated by a geographic barrier (river, mtn. etc)
53
Geographic Isolation
54
When a species doesn’t recognize another species as a mate because it didn’t do the correct mating dance or call or make the correct display
55
Behavioral Isolation
56
When 2 species mate at different times
57
Temporal Isolation
59
When members of a population can no longer interbreed with the rest of the population is called?
60
Reproductive Isolation
61
Large scale evolution that takes place over a long period of time
62
Macroevolution
63
What percentage of species that lived on earth have become extinct?
64
99%
65
Where two or more species originate from one species called a common ancestor.
66
Divergent Evolution
67
Where 2 different species evolve in response to one another.
68
Coevolution
69
What is it called when 2 different species inhabit similar environments and evolve similar traits.
70
Convergent Evolution
