This is a characteristic that
helps an organism survive and
reproduce in its environment
A 100
What is an adaptation?
.
A 100
When inherited
characteristics within a
population change over time
.
A 200
What is evolution?
.
A 200
An example of this was used to
extract DNA to create the
dinosaurs at Jurassic Park.
A 300
What is a fossil?
.
A 300
Skeletal structure and DNA
A 400
What are two ways we can
compare organisms?
A 400
This young man didn't know
what he wanted to do after
college. So he set sail on the
HMS Beagle and collected plant
and animal specimens
A 500
Who is Darwin?
A 500
Specific characteristics that can
be passed on from one
generation to the next AND the
process in which humans select
these to be passed on in plants
and animals.
B 100
What are traits and selective
breeding?
.
B 100
The process which by
individuals that are better
adapted to their environment
survive and reproduce more
successfully than less well
adapted individuals do. This is a
theory to explain evolution.
B 200
What is Natural Selection?
B 200
A tarantulas egg sac can hold ~
1,000 eggs. What is this an
example of?
B 300
Overproduction
.
B 300
When a single population
evolves into two populations that
cannot interbreed
anymore__________ has
occurred.
B 400
What is speciation?
B 400
Darwin noticed this when observing these birds.
B 500
.
What is their beaks adapted to
being able to obtain certain foods?
B 500
An example is a tuskless
elephant
C 100
What is an adaptation to
hunting?
C 100
The average time between one
generation and the next.
.
C 200
What is generation time?
C 200
An example of this is when a
mountain range, canyon or lake
forms between a population
C 300
What is separation?

C 500
What is competition for mates?
C 500
List 2 ways that fossils can form.
D 100
What is by being buried in
sediment and by getting stuck
in tree sap (amber)
D 100
Estimating the age of rocks and
fossils by comparing the oldest
and newest layers.
D 200
What is relative dating?
D 200
This method measures the age of
rock in years.
D 300
What is absolute dating?
D 300
This is the most precise type of
fossil dating.
D 400
What is absolute dating?
D 400
Precambrian time, Paleozoic,
Mesozoic and Cenozoic are all
examples of this…..
D 500
What are eras?
D 500
During this time Earth was a
violent place filled with volcanic
eruptions, meteors and had a
harsh atmosphere..
E 100
What is Precambrian time?
E 100
This is the most important thing
that evolved during Precambrian
time. It’s by-product is oxygen.
E 200
What is cyanobacteria?
E 200
These types of creatures dominated this era.
E 300
What is the Cenozoic era?
E 300
The largest mass extinction
occurred during this era.
E 400
What is the Paleozoic era?
E 400
The Age of Reptiles
E 500
What is the Mesozoic era?
E 500
This group has opposable
thumbs.
F 100
What are primates?
F 100
This is the main characteristic
that separates hominids from
other primates.
F 200
What is bipedalism?
F 200
This hominid had both ape like
and human like characteristics.
F 300
What is Australopithecines?
F 300
Homo erectus and Homo habilis
are examples of this
F 400
What are global hominids?
F 400
This recent hominid made fire,
wore clothing and hunted large
mammals.
F 500
What are Neanderthals?

The Final Jeopardy Category is:
Darwin’s Natural Selection
Please record your wager.
Click on screen to begin
List AND explain the four parts of
Darwin’s Natural Selection
Click on screen to continue
Overproduction- Laying lots of eggs because some will survive and some will not.
Inherited Variation- Every individual has its own combination of traits. Similar
but not identical to its parents.
Struggle to Survive- Some may be caught by predators, some may starve or get a
disease. Only some survive to adulthood.
Successful Reproduction- The individuals that are best adapted to their
environment are likely to have many offspring that survive.
