Darwin's Work
Evidence for Evolution & Adaptations
How Else Can Populations Change?
Vocabulary
100
This is the name of the islands that Darwin traveled to in 1835.
What are the Galapagos Islands
100
This is the animal that Darwin began studying in England to collect evidence for his hypothesis.
What are pigeons
100
This type of evidence for evolution shows transitional organisms (i.e. organism between fish and tetrapods).
What are fossils
100
These can be both harmful and beneficial.
What are mutations
100
This is cumulative changes in groups of organisms through time.
What is evolution
200
This is the name of the boat that Darwin boarded in 1831.
What is the HMS Beagle
200
This is the man that wrote an essay in which he described a world with few resources and much competition; Darwin applied this to his own theory.
What is Thomas Malthus
200
An example of this would be the presence of the humerus in both humans and whales.
What is a homologous structure
200
Peacocks exhibit this type of selection.
What is sexual selection
200
This is a structure that is a reduced form of an ancestral structure; not utilized by the organism
What is a vestigial structure
300
This man was an ornithologist that revealed that the finches that Darwin brought back to England with him were different species.
Who is John Gould
300
This term describes an outside breeder selecting the most desired traits to pass from parents to offspring.
What is artificial selection
300
Evidence for evolution includes the fossil record, comparative anatomy, geographic distribution, comparative embryology, and this.
What is comparative biochemistry
300
When this type of selection occurs, the extremes are eliminated and most organisms exhibit the average phenotype.
What is stabilizing selection
300
This is a type of selection in which the two extremes are selected for.
What is disruptive selection
400
This is the basis for Darwin’s theory of evolution and states that those best suited to an environment will reproduce and those unsuited will eventually die off.
What is natural selection
400
This term is used to describe the fact that all individuals in a population show some differences from one another.
What is variation
400
This is an adaptation in which the offspring of an organism begin to resemble a toxic or poisonous organism because the predator of the organism avoids any organisms that look toxic.
What is mimicry
400
is term describes when two different species are able to interbreed, but produce sterile offspring.
What is postzygotic isolation
400
This is a measurement of the relative contribution an organism makes to the next generation.
What is fitness
500
This is the name of the book that Darwin published in 1859 describing his hypotheses.
What is On the Origin of the Species by Means of Natural Selection
500
This is one of Darwin’s four basic principles of natural selection.
What are: 1) individuals show variation, 2) variations can be inherited, 3) organisms have more offspring than can live off of the resources, and 4) traits increase reproductive success more likely to be passed down
500
This is a structure that is used for the same purpose in two different organisms, but did not arise from the same ancestor.
What is an analogous structure
500
This is the term used to define when a small sample of a larger population settles in a location separated from the rest. Because of this, the diversity of the gene pool is diminished.
What is the founder effect
500
This is the study of the distribution of plants and animals around the world.
What is biogeography
