According to the theory of natural selection, the individuals that survive are those that . . .

variations best suited to the environment

Charles Lyell's observations led him to believe that:

the Earth was far older than 6,000 years., gradual changes over time have greatly changed the Earth.

Microevolution can be thought of as:

changes in the frequencies of alleles in a gene pool

Identify the purpose of transitional forms of fossils(L1)

To show the series of changes used to adapt to environment

Evolution can be seen in the fossil record in which of the following ways?

fossils shows evidence that organisms have changed over time

The bottleneck effect is:

population when few members of a species survive an event

What is comparative anatomy

the comparison of different structures in organisms

The process of evolution takes place:

over many generations of a population

Evolution is the process of

change in species over long periods of time

What is a Binomial Nomenclature

Naming system gives each organism a two-word scientific name

What is an adaptation?

A change that helps something survive

Which barriers contribute to reproductive isolation?

Offspring inviability or sterility, evolution of different mating location, time, or rituals

Biogeography is the study of ...

the distribution of plants and animals in particular areas

when does the founder effect occur?

new colony is started by members of the original population

According to the theory of natural selection, the individuals that survive are those that . . .
the greatest number of offspring
have characteristics acquired by use and disuse
have characteristics that plant and animal breeders value
variations best suited to the environment
2
Charles Lyell's observations led him to believe that:
the Earth was far older than 6,000 years.
gradual changes over time have greatly changed the Earth.
forces that no longer exist have shaped the Earth.
the Earth was unchanged from the time it formed.
3
Natural Selection operates on what level of organization?
Molecular
Population
Individual
Species
4
Microevolution can be thought of as:
reacting to changes in the environment
changes in the frequencies of alleles in a gene pool
creating new species where none existed before
genes mutating in response to environmental change
5
Identify the purpose of transitional forms of fossils(L1)
To complete the fossil record
To show the series of changes used to adapt to environment
To compare environments
To disprove evolution
6
Evolution can be seen in the fossil record in which of the following ways?
Organisms fossils record are identical to living organisms.
fossils shows evidence that organisms have changed over time
Fossil shows that organisms developed at the same time
Individual species disappear &reappear in the fossil record

9
The bottleneck effect is:
zero population growth
a logistic population crash
a sudden declination in population of a species
population when few members of a species survive an event

What is comparative anatomy
If two species have similar DNA prob. have the same ancestor
the comparison of different structures in organisms

Naming system gives each organism a two-word scientific name
A taxon
A group of organisms
18
Genetic drift has a greater effect in?
varied populations
large populations
small populations
unvaried populations
19
Natural Selection
The process of all things being changed over time
When organisms learn how to capture prey
Survival of the fittest
Becoming adjusted to different conditions
20
What is an adaptation?

24
Biogeography is the study of ...
fossil types and their relation to living organisms
the distribution of plants and animals in particular areas
mountain ranges and rivers
islands and their distances from continents
25
Natural Selection acts directly on:
alleles
genes
phenotypes
mutations
26
when does the founder effect occur?
a large population is able to move into a new environment
small populations become isolated
new colony is started by members of the original population
Gene flow between two previously separated populations
