Download adaptation adaptive radiation analogous structure artificial selection

Any inherited
characteristic that
increases an organism’s
chance for survival.
A single species evolves
into different forms due
to natural selection and
various forms of
isolation.
Structures with similar
functions that did not
come from a common
ancestry, but from
sharing a similar
environment.
Selection caused by
humans (also called
selective breeding).
adaptation

artificial
selection
An isolating mechanism that
occurs between two
populations that are capable
of interbreeding but because
of reproductive strategies that
involve behavior they do not
mate.
Came up with the idea
of natural selection.
Two species evolve in
response to changes in
each other.
All living things are
derived from common
ancestors.
behavioral
isolation
Charles Darwin
coevolution
common
descent
Unrelated organisms
that come to resemble
one another because
they share the same
environment.
Each living species has
descended with changes
from other species over
time.
The type of selection
that occurs when
individuals at either side
of the normal distribution
curve are favored.
When individuals at the
upper and lower ends of
a normal distribution
curve have greater
fitness than those near
the center of the curve.

selection
Change over time.
evolution
The ability of an
organism to survive and
reproduce in a specific
environment.
fitness
A situation in which a
change in allele
frequencies occurs as a
result of migration of a
subgroup.
founder effect
All of the genes in a
given population.
gene pool
A random change in
allele frequency that
occurs as a result of
chance.
No evolution, due to:
random mating, large
population, no
immigration or
emigration, no mutation,
no natural selection.
Type of reproductive
isolation that deals with
physical barriers like
mountains or rivers.
Length of time for half of
the radioactive atoms in
a sample to decay.
genetic drift
genetic
equilibrium
geographic
isolation
half-life
A mathematical equation
dealing with the fact that
allele frequencies
remain constant unless
one or more factors
cause a change to occur
Structures with different
mature forms, but look
similar in the embryonic
form.
A recognizable fossil of
an organism that lived
for a short period of
time, but over a wide
geographic range.
Came up with the idea
of the inheritance of
acquired traits.
Hardy-Weinberg

homologous
structure
index fossil
Jean-Baptiste
Lamarck
When multiple species
permanently die out
during the same time
frame.
Term that means
survival of the fittest.
Traits that are controlled
by more than one gene.
A pattern of evolution
where long stable
periods are interrupted
by brief periods of rapid
change.
mass extinction
natural selection
polygenic trait
punctuated
equilibrium
Using the half-life of an
isotope to find the
absolute age of a fossil.
Using index fossils to
find the approximate age
of a fossil.
The number of times
that the allele occurs in
a gene pool compared
with the number of times
other alleles for the
same trait occur.
When members of a
species can no longer
interbreed, this form of
isolation occurs which
over time can lead to
speciation.

reproductive
isolation
Traits controlled by one
gene.
The formation of a new
species.
Type of selection which
occurs when individuals
near the center of the
curve are favored.
Members of the same
species compete for
food, living space, and
other necessities.
single-gene trait

struggle for
existence
An isolating mechanism
where difference in
reproductive times
results in speciation.
A well-supported
testable explanation of
phenomena that have
occurred in the natural
world.
A structure that seems
to have no use.
