_____ is a trait may develop
quickly – example: antibiotic
resistance
Physiological Adaptation
Any body structure that is reduced
in function is known as a _______
Vestigial structure
______ is the splitting of 1 species
into 2 or more
speciation
Similarities in structure and
arrangement—likeness indicates a
genetic relationship through a
common ancestor is known as ______
Homologous structures
Which type of genetic drift is
caused by catastrophic events like
a natural disaster or habitat loss?
Bottleneck effect
What is the random effect that can
occur when a small population settles
in an area separated from the rest of
the population and interbreeds,
producing unique allelic variations?
Founders effect
A brown mouse blends in with his
surroundings. This is an example
of ________
Camouflage
List a vestigial structure in
humans.
Wisdom teeth
Appendix
Ear muscles
Change in allele frequencies in a
gene pool due to chance is known
as _______
Genetic Drift
Two organisms live in close proximity,
but rarely interact due to living in
different habitats. This is known as
__________ isolation.
Habitat
The environment acted directly on
organisms to produce hereditary
change in relation to need, use or
disuse is known as _____________
Acquired Traits
_____ is the process in which a
large population declines in
number, then rebounds
Bottleneck effect
What type of evolution happens in
a shorter amount of time?
Microevolution
Who’s theory was based on the idea
that the environment acted directly
on organisms to produce hereditary
change in relation to need, use or
disuse.
Lamark
When one organism looks like a
dangerous organism, this is a
structural adaptation called_____.
mimicry
___________ is a change in the gene
pool of a population in response to
various stimuli exhibited by a species
OVER TIME
Evolution
It is impossible for a monkey and a
lion to reproduce. This is known
as____ isolation.
mechanical
Which type of evolution requires
speciation?
Macroevolution
__________ may arise over many
generations (Ex: mimicry and
camouflage)
Structural adaptations
Two species are separated by an
ocean. This is referred to
as_________ isolation.
Geographic
_________ is evolutionary change
below the level of species, and refers
to changes in the frequency within a
population or a species of its alleles
Microevolution
What is the name of the ship
where Darwin did his studies for
his evolution theory?
HMS Beagle
Two species of frogs live in close
proximity, but reproduce at different
times of the year. This is known as
___________ isolation.
Temporal
__________ is any evolutionary
change at or above the level of
species.
Macroevolution
What organism did Darwin use to
base a lot of his evolutionary
ideas?
Finches
Two species of birds, meadowlarks,
have overlapping ranges and are
similar in appearance, but their songs
separate them. This is known
as_________ isolation.
Behavioral
If a lion and a tiger mate, their
offspring is a liger. The liger is sterile
and cannot reproduce. This is known
as________ isolation.
Gamete
Any trait that aids the chances of
survival and reproduction
of an organism is known as
__________
Adataption
