25 Questions

1.
Geographic distribution of species

2.
Selection by humans for breeding of useful traits from the natural variation among different organisms

3.
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.

4.
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.

5.
Change in a kind of organism over time; process by which modern organisms have descended from ancient organisms.

6.
Selection in which a mate is chosen on the basis of a particular trait or traits

7.
A characteristic that improves an individual's ability to survive and reproduce in a particular environment.

8.
Evolutionary change in which adaptations in one species act as a selective force on a second species, inducing adaptations that in turn act as a selective force on the first species; mutual influence on the evolution of two different interacting species.

9.
A procedure in which the reinforcement of a previously reinforced behavior is discontinued. Also may be used to describe the 'process' by which a previously learned behavior disappears as a result of non-reinforcement.

10.
An evolutionary theory (proved false by Darwin) stating that species change over time by the use and disuse of structures and the inheritance of acquired traits.

11.
A change in the allele frequency of a population as a result of chance events rather than natural selection.

12.
English natural scientist who formulated a theory of evolution by natural selection (1809-1882)

13.
Genetic drift that occurs when a few individuals become isolated from a larger population and form a new population whose gene pool composition is not reflective of that of the original population.

14.
Process by which unrelated organisms independently evolve similarities when adapting to similar environments

15.
Preserved remains of once-living organisms

16.
A form of evolution in which the same organism is placed into different environments with different selection pressures. This causes organisms to evolve differently, to diverge from their common ancestor. The resulting (new) species may share structural (but not necessarily functional) similarity; divergent evolution produces homologous structures.

17.
A structure that is present in an organism but no longer serves its original purpose

18. The biological process whereby genetic factors are transmitted from one generation to the next

19.
A process typically caused by the genetic isolation from a main population resulting in a new genetically distinct species.

20.
Structures that have different mature forms in different organisms but develop from the same embryonic tissues

21. Any barrier that prevents genetic exchange between species

22. any change to the genetic code that results in noticeable physiological changes that are of benefit to the organism

23.
Process by which individuals that are better suited to their environment survive and reproduce most successfully; also called natural selection

24.
is a mutation that decreases the fitness of the organism.

25.
The formation of a new species as a result of an ancestral population's becoming isolated by a geographic barrier.
