answer
question
$200
What is Artificial Selection?
Farmers only allowing the
best animals to breed is an
example of this process.
$400
What are use/disuse, passing on of acquired
traits and desire to change?
Larmarck made these 3 false
assumptions.
$600
What are the earth is older than once
thought and has changed over time?
Lyell made these two key
observations regarding the
earth.
$800
What is war, famine and disease are
necessary to keep populations in check?
Malthus made these rather
unpopular opinions known
regarding population
dynamics.
$1000
What is On The Origin of Species?
In 1859, Charles Darwin finally
published his conclusions in this
famous book.
$200
What is dying doing something incredibly
stupid?
A Darwin award is granted to
any person meeting these two
conditions.
$400
What is survival of the fittest?
Individuals whose characteristics
are best suited to their environment
survive and reproduce leaving more
offspring describes this principle.
$600
What are selective pressures?
Factors in the environment
that either favor or
disadvantage members of a
species are known as these.
$800
What is fitness?
Physical traits and behaviors that
help an organism survive and
reproduce in its environment are
better known as this term.
$1000
What is the process in nature that results in
the most fit organisms producing more
offspring and dominating the gene pool of
the next generation?
Natural selection may be
defined as this.
$200
What is the fossil record?
This is considered the only
“direct” evidence of evolution
taking place.
$400
What are homologous structures?
Body parts that come from a
common origin, but which
may look radically different
are known as these.
$600
What are vestigial organs?
These body parts are
remnants seemingly left
behind during evolution and
are no longer of use to the
organism having them.
$800
What are analogous structures?
These body parts appear
similar in both appearance
and function despite having
very different origins.
$1000
What are finch beak size on Daphne Major
and the Peppered Moth in England?
These two examples of
evolution in action show
species changing in response
to their environment.
$200
What is extinction?
This occurs when a species is
unable to adapt successfully
to a changing environment
and results in the species
dying out.
$400
What is gradualism?
This theory of evolution
prescribes to a slow
progression of change over
long periods of time.
$600
What is punctuated equilibria?
A pattern of long stable
periods interrupted by brief
periods of change is better
known as this.
$800
What is variation due to sexual
reproduction?
This factor often prevents a
species from being
completely wiped out during
periods of change in their
environment.
$1000
What is genetic research?
This area of scientific
research is likely to yield the
most useful information and
shape modern evolutionary
theory in the future.
$200
What are genes?
These are considered the raw
materials of evolution.
$400
What is genetic drift?
A random change in the
frequency of a gene is known
as this concept.
$600
What are mutations?
Random changes in the
genetic code of an organism
are known as these.
$800
What is an allele?
A specific form of any
individual trait is known as
this.
$1000
What is the relative frequency of alleles for
a particular trait?
Natural selection will result
in a shift in this within a
population’s gene pool.
$200
What is speciation?
The creation of a new species
from a single original species
may be defined as this.
$400
What is convergent evolution?
The adaptation of structures that
perform the same function due to
similar environmental pressures
results in this evolutionary process.
$600
What is Adaptive Radiation?
When one species gives rise
to many it is known as
divergent evolution. Another
name for this process is this.
$800
What is niche?
The combination of an organisms
place and occupation within its
ecosystem is better known by this
term.
$1000
What are ancestors, separation of
populations, changes in the gene pool,
reproductive isolation and sharing the same
environment?
Speciation requires five
distinct stages. In order,
these are the five stages.
