Q

Two points Charles darwin made in his book

A
  • presented evidence that many species of organisms are descendants of ancestral species
  • proposed a mechanism for the evolutionary process, natural selection

Geologists Hutton and Lyell

24
Q

Wrote an encyclopedia of nature; suggested that species could degenerate in to other species

A

Leclerc comte de buffon

25
Buffon's evidences
Similarity in limb structure of mammals and between related species
26
Charles's grandfather; suggested that life evolved from a common ancestor
Erasmus darwin
27
Erasmus darwin's evidences
Homology, artificial selection of domestic breeds
28
A vertebrate morphologist who believed that form dictates function (archetype)
Etienne Geoffroy - St. Hilaire
29
Evidence of St Hilaire
Homologous structures, vestigial traits, embryonic changes
30
Strong advocate of evolution; hypothesized that species evolved through use and disuse and inheritance of traits
Jean baptiste lamarck
31
Darwin proposed that species change through ________
Natural selection
32
The ship Darwin took to go to Galapagos
Beagle
33
He developed a theory of natural selection similar to darwin's; sent darwin a manuscript
Alfred russell wallace
34
Darwin's two main ideas
Evolution explains life's unity and diversity; natural selection is a cause of adaptive evolution
35
This phrase summarized darwin's perception of the unity of life; states that all organisms are related through descent
Descent with modification
36
Meaning of descent
Common ancestry, homology, relation, biogeography
37
What does modification denote
Change over time, vestigial traits, selective breeding, direct observation, fossil
38
What did darwin observe in galapagos
Marine iguanas, land tortoises, finches
39
Humans have selected plant and animal traits which benefit mankind; examples
Artificial selection; dog domestication, increase crop yield
40
Ability to pass on genes
Survival of the fittest
41
Force that drives evolution; individuals better adapted survive and leave more offspring; process by which individual organisms with favorable traits survive and reproduce
Natural selection
42
Components of natural selection
variation; differential reproduction; heredity
43
Mechanism for evolution
Variation
44
These are the environmental issues and illnesses that compose natural selection
Differential reproduction
45
Brown beetles that are left will mate and have brown offsprig
Heredity
46
Examples of natural selection
Orchid fool wasps, nonpoisonous snakes mimic poisonous snakes, katydids camouflage leaves
47
Factors of natural selection
Gene pool must vary (from mutation, immigration and emigration), variety must be inheritable, there must be competition
48
Evidence of evolution
Fossils (most direct evidence) , similar dna sequences (molecular level- gene and protein comparisons), homologous organs (similar in structure, diff in function), embryology
49
4 forces of evolutionary change
Genetic drift, gene flow, mutation, natural selection
50
Genetically based differences in survival or reproduction that leads to genetic change in population
Natural selection
51
Spontaneous changes in dna; results of mistakes
Mutations
52
Movement of genes between populations
Gene flow
53
Random changes in gene frequency
Genetic drift
54
Modes of natural selection
Stabilizing selection, directional selection, diversifying selection
55
Eliminates extreme phenotypes
Stabilizing selection
56
Shifts average in one dyrection by favoring one of the extreme phenotypes; anagenesis
Directional selection
57
Splits a population into 2 parts favoring both extremes ; cladogenesis
Diversifying selection
