The HMS
Beagle
What was the
name of
Charles
Darwin’s navy
ship?
The
Galapagos Islands
Where did
Darwin travel
to?
Darwin observed
these animals as
having an
adaptation
What are
finches?
Darwin’s
important
scientific
theory
What is the
theory of
evolution by
natural
selection?
A well tested
concept that
explains a
wide range of
observations
What is the
scientific
theory?
More species
are produced
than can
survive
What is
overproduction
?
Lions move in
on the tigers
and take their
home
What is
competition?
Animals of the
same species
have
differences
among them
What is
variation?
Individuals
that have
helpful traits
are more likely
to survive
What is
selection?
A hawk has
black feathers
while another
hawk has
brown feathers
What is
variation?
This is how
most fossils
form
What is buried
in sediment?
The problem
with the fossil
record
What is it has
gaps?
Members of a
species no
longer exist.
What is
extinction?
This tells
about
organisms
from the past
What is a
fossil record?
Found in the
seas about
540 million
years ago
What are the
first animals?
Evolution
occurs slowly
over time
What is the
theory of
gradualism?
These three
things are used
to determine
evolutionary
relationships
What is body
structure,
DNA, and early
development?
Similar
structures that
related
species have
What are
homologous
structure?
chimpanzees
What are
believed to be
our most
closest
relative?
Chickens and
turtles that
look almost
exactly alike
What is an
example of
early
development?
Pangaea
What is the
process of
continental
drift called?
This leads to
changes
What are
helpful
mutations or
variations?
A group of
individuals are
separated for
long periods of
time
How does a
new species
form?
River, volcano,
mountain
range, and an
ocean wave
What are
conditions that
can separate a
group from its
species?
The Kaibab
squirrel
developed
from this
original
species
What is the
Abert squirrel?
What are
homologous
structures?
What is a
branching
tree?
What is
Pangaea?
Who is Charles
Darwin?
What is an
example of
early
development?
The theory that explains
the lack of intermediate
forms of fossils.
What is
punctuated
equilibria?
