100
This scientist is known as the father of evolutionary theory.
Who is Charles Darwin?
100
Provides a record over time, shows that ancient species have similarities to modern ones
What is the fossil record (fossils)?
100
If a population changes so that turtles with the longest necks have an evolutionary advantage, we say that this type of selection has occurred.
What is the directional selection?
100
All the members of a species in a particular area make up this.
What is a population?
100
Any trace or remains of a once-living organism that has been preserved by natural processes.
What is a fossil?
200
Organisms with fitness often have more ____________ that will survive.
What are offspring?
200
Our chicken wing / human arm bone comparative anatomy lab was intended to show that wings and arms are these type of structures.
What are homologous structures?
200
This is an example of geographic isolation.
Accept all answers that have a population split apart by a physical barrier.
200
This is the term for all the alleles in a population.
What is a gene pool?
200
Cytochrome c is a highly conserved protein found across the spectrum in species of plants, animals, and many unicellular organisms. Finish the statement based on your knowledge from this chapter: the more similar the # of amino acids making up cytochrome c in two organisms, the...
...more closely related they are
300
The Galapagos islands provided material for Darwin's theory, especially in the form of these types of birds with their varying beak shapes.
What are finches?
300
Dolphins and sharks are not closely related but have a very similar look due to this type of evolution pattern.
What is convergent evolution?
300
This type of natural selection favors the average form of a trait.
What is stabilizing selection?
300
Organisms that breed and produce sterile (non-fertile offspring) exhibit this type of reproductive isolation.
What is postzygotic?
300
What is convergent evolution?
400
On the black sand beaches of Hawaii there are 2 beetle colonies, one silver and the other black. The black beetles will survive at a higher rate and pass the black trait onto offspring. We then say they have a high level of...
What is fitness?
400
The presence of a human appendix suggests this about our ancestors.
What is "they used it" or it was useful to them?
400
What is disruptive selection?
400
This is the term for the process in which members of one population become isolated from one another and enough time passes such that the populations are exposed to different conditions, they will no longer be able to breed, therefore becoming separate species.
What is speciation?
400
The appendix or tail bone in humans is an example.
What is a vestigial structure?
500
These are the 4 concepts on which natural selection acts
What are:
Variation, Inheritance, Overproduction, and Reproductive Advantage?
500
Microevolution works at a population level - this is the definition of how a scientist would know that microevolution has occurred.
What is a change in the relative frequency of an allele in a gene pool?
500
This can be inferred about the evolutionary history of 2 species if they share homologous structures
What is common ancestry?
500
This is the term for when a change in an allele frequency in a population occurs due to chance.
What is a genetic drift?
500
Circumstances such as behavioral, geographic, or temporal isolation all come under the category of this type of reproductive isolation.
What is prezygotic isolation?
