Differences
between members
of the same species
are called_____.
A trait that
helps an organism
survive and
reproduce is
called a(n) _______
Which term refers to the
process by which individuals
that are better adapted to
their environment are more
likely to survive and
reproduce?
Give an example
of how a species
will change over
time.
How will a mutation affect an
organism’s chance of
survival?
Which term refers to the
process by which
individuals that are better
adapted to their
environment are more
likely to survive and
reproduce?
How does natural selection lead
to evolution?
A. Stronger offspring kill weaker members of
the species.
B. Helpful traits accumulate among surviving
members of the species.
C. Overproduction provides food for stronger
members of the species.
D. Environmental changes kill weaker
members of the species.
B.
Helpful traits
accumulate among
surviving members of
the species.
New species formed
when groups were
isolated by the process
of
_________________________,
in which Pangaea split
apart.

Give an example of how
a mutation could be an
advantage.
Answers will Vary
Explain why
variations are needed
for Natural Selection
to occur?
Otherwise all
individuals would be
adapted to their
environment and
equally likely to
survive and reproduce.
Which fruit phenotype
(physical characteristic)
reached the ground most
often?
Why?
Which trait of the Catchecans
allows them to be most
successful in meeting family
food needs?
Why?
Consider the future of the
Swiftus supersonicus .
What are you going to do with these birds?
They are eating the fruit that could feed
more Catchecans.
Suggest a method by which the problem
could be solved without endangering the
species.
Using the underlined words explain how
variation,
adaptation,
survival,
and reproduction,
have played a vital role in the way the Catchecans
have changed over the generations.
Write the explanation in your notes.
There are many variations amongst
members of the Catchecan tribe. One
adaptation they have developed is fast
reflexes. Survival is dependant upon the
ability to catch Bebblefruit. Those who feed
their family will ensure that their traits will
be reproduced in future generations.
What would happen to
the Catchecans who
always fed their last
born first?
How will
humans impact
the evolution
of man’s best
friend, the
dog?
Name a change or
adaptation that may
be occurring in the
human population on
Earth?
How will climate
change affect the
polar bear
species?
Identify a logical reason
as to why this animal
exhibits these traits.
What characteristic of the
human race will ensure its
survival in the future?
