FINAL JEOPARDY
Similar structures
from common
evolutionary origins
are called…
Answer
• Homologous Structures
Leg bones present
in a snake
skeleton are an
example of what?
Answer
• Vestigial Structures
Name 2 features
present in vertebrate
embryos that suggest
common evolutionary
origins.
Answer
• Tails
• Pharangeal pouches (gill
slits)
• Limb buds
List the 5 different
types of fossils.
Answer
• Molds
• Petrified
• Casts
• Amber-preserved
• Imprint
Structures that are
similar in function but
have evolved
separately are called
what?
Answer
• Analagous Structures
The concept that evolution
occurs over long periods
of stability that are
interrupted by geologically
brief periods of change is
called…
Answer
• Punctuated Equilibrium
_______________ is a type
of selection that favors two
extreme traits.
Answer
• Disruptive
_________ __________ is
a mechanism for change in
a population in which
organisms with favorable
variations live, reproduce,
and pass on their favorable
traits.
Answer
• Natural Selection
This graph depicts which
type of selection?
Answer
• Stabilizing Selection
–The average or middle are
favored
–Extremes are NOT favored
Explain why
individuals compete
to survive.
Answer
• Living organisms overproduce
(too many offspring)
• Limited resources
An insect has evolved to
look like a leaf, allowing
it to blend in with its
environment. This is an
example of…
Answer
• Camouflage
Draw a graph
depicting directional
selection.
Answer
One extreme is favored
Where did Darwin
travel to study
organisms?
Answer
• Galapagos Islands
How were Darwin’s
finches different
from each other?
What explained
these differences?
Answer
• Their beaks were different
• Their beaks were adapted to
their diets.
Darwin wrote what
book to explain his
theory of
evolution?
Answer
• On the Origin of Species
List the four parts of
Darwin’s theory of
evolution.
Answer
• Living organisms produce too
many offspring
• There is variation among the
offspring
• There is a struggle to survive
(competition)
• Individuals that have desirable
traits will survive and reproduce.
In a piece of rock
layers, where would
you find the oldest
fossils?
Answer
• At the bottom
A pink lump in the
corner of the human
eye does not serve a
purpose anymore.
This is an example
of…
Answer
• Vestigial Structure
The concept that
evolution occurs
at a slow, steady
pace is called…
Answer
• Gradualism
What are the five
types of evidence
for evolution?
Answer
• Speciation Rates
• Fossils
• Anatomy
• Biochemistry
• Embryology

• Question
FINAL JEOPARDY
When studying the evolution of
insects, you find that some male
insects are able to remove the
sperm packet of another male
from the reproductive tract of a
female. Explain how this is a
selective advantage for males.
Answer
• The male insect can remove the
other male’s sperm and replace
it with his own sperm into the
female.
• This way, he ensures that his
genes get passed on to the next
generation.
