2. Definition
Inherited from a common
ancestor, may have a similar
structure but different function.
Similar because of convergent
evolution, and not because of
common ancestry, may have a
similar function but a different
structure.
A change in a DNA sequence,
usually occurring because of
errors in replication or repair.
Physical appearance of an
organism.

using colors and markings to look
like another animal.

2. Definition
Generally, a group of organisms
living close to one another that
interbreed with one another and
do not breed with other similar
groups.
All of the genes in a population.
Any genes that could wind up in
the same individual through
sexual reproduction.
Changes in gene frequency in a
population from one generation
to the next.
A process in which some
individuals have geneticallybased traits that improve
survival or reproduction and thus
have more offspring surviving to
reproductive age than other
individuals.
The process of changing the
characteristics of animals by
artificial manual means. a
process in which humans
consciously select for or against
particular features in organisms.

2. Definition
Random changes in gene
frequency that is more obvious in
smaller populations but that
occurs in all populations.
A structure or organ that has
diminished in size or usefulness
in the course of evolution. These
are used as markers of
evolutionary descent.
An evolutionary process that
does not require large-scale
geographic distance to reduce
gene flow between parts of a
population. Occurs rarely.
An evolutionary process in which
one species divides into two
because 1)the original population
is separated 2)both groups
diverge from each other and 3)
reproduction isolation occurs.
The separation of populations by
barriers such as rivers,
mountains, or bodies of water.

2. Definition
An effect of genetic drift
attributable to a temporary
reduction in population size.
An effect of genetic drift
attributable to colonization by a
limited number of individuals
from a parent population.
Two populations are isolated if
their members are unable to
interbreed and produce fertile
offspring. Structural, behavioral,
and biochemical features can
prevent interbreeding and thus
isolate populations as distinct
species.
K. A theory of evolution
advocating spurts of relatively
rapid change followed by long
periods of stasis.
a branch of biology dealing with
embryos and their development
