Q.
Genetic change in a population of organisms over time
2
30 sec
Q.
Breeding organisms with specific traits in order to produce offspring with identical traits.
3
30 sec
Q.
A process in which individuals that have certain inherited traits tend to survive and reproduce at higher rates than other individuals because of those traits.
4
30 sec
Q.
small scale - changes in gene frequencies within a species
5
30 sec
Q.
A trait that helps an organism survive and reproduce
6
30 sec
Q.
The preserved remains or traces of an organism that lived in the past
7
30 sec
Q.
similar structures with different functions
8
30 sec
Q.
different structure, same function
9
30 sec
Q.
remnant of a structure that may have had an important function in a species' ancestors, but has no clear function in the modern species.
10
30 sec
Q.
the formation of new and distinct species in the course of evolution.
11
30 sec
Q.
Process by which unrelated organisms independently evolve similarities when adapting to similar environments
12
30 sec
Q.
the accumulation of differences between groups which can lead to the formation of new species
13
30 sec
Q.
A change in the allele frequency of a population as a result of chance events rather than natural selection.
14
30 sec
Q.
change in allele frequencies as a result of the migration of a small subgroup of a population
15
30 sec
Q.
a reduction in the genetic diversity of a population caused by a reduction in its size
16
30 sec
Q.
Movement of alleles into or out of a population due to the migration of individuals to or from the population
17
30 sec
Q.
The formation of new species in populations that are geographically isolated from one another.
18
30 sec
Q.
populations of the same species that differ genetically because of adaptations to different living conditions
19
30 sec
Q.
The formation of a new species as a result of a genetic change that produces a reproductive barrier between the changed population (mutants) and the parent population. No geographic barrier is present.
20
30 sec
Q.
Diagram that shows the evolutionary relationships among a group of organisms
21
30 sec
Q.
Method of determining the age of a fossil by comparing its placement with that of fossils in other layers of rock
22
30 sec
Q.
any method of determining the age of a fossil by measuring the decay of radioactive material.
23
30 sec
Q.
The more DNA or amino acid sequence that organisms share, the more closely they are related.
24
30 sec
Q.
similarities in the development of embryos between different species that share a common ancestor
25
30 sec
Q.
the comparison of body structure between different species
26
30 sec
Q.
Resistance evolving rapidly in many species of prokaryotes due to overuse of antibiotics, especially in agriculture.
27
30 sec
Q.
the ability of a pest to withstand exposure to a given pesticide; the result of natural selection favoring the survivors of an original population that was exposed to the pesticide
28
30 sec
Q.
natural selection in which individuals at the upper and lower ends of the curve have higher fitness than individuals near the middle of the curve
29
30 sec
Q.
Natural selection in which individuals at one end of the phenotypic range survive or reproduce more successfully than do other individuals.
30
30 sec
Q.
Natural selection that favors intermediate variants by acting against extreme phenotypes
