What is a species?
A group of similar organisms that can interbreed with one another.
100
Preserved remains of ancient organisms are known as
Fossils

Name 1 cause of speciation.
Reproductive isolation
Geographic isolation
Limiting factors
200
How does comparative embryology support the theory of evolution?
Indicative of a common ancestor
200
Why was there an increase in Dark Peppered Moths during the Industrial Revolution?
Their environment became polluted so they blended in better and had a better likelihood of surviving and reproducing.
200
In the bird beak lab, which tool represented a specialist and why?
Toothpick-- it could only pick up certain foods
200
DOUBLE JEOPARDY (400 POINTS): What is one example of a vestigial structure in humans?
Tailbone
Appendix
Gill arch
Etc.

In order to produce fertile offspring, what must be true about an organism's chromosomes? (Hint: Think about how a horse + donkey = infertile mule)
The must have an even number of chromosomes so they can pass on half to their offspring.
300
List the 4 forms of evidence that support the theory of evolution.
1. Fossils
2. Comparative anatomy
3. Anatomical/Morphological Structures (Homologous, Analogous, Vestigial)
4. Molecular Biology-- DNA evidence

Giraffes, deer, and antelope are closely related. What adaptation did giraffes evolve that allowed them to specialize?
Their long necks help them to eat from the tops of trees.
300
How are humans similar to whales?
They have homologous structures, similar bone structure in their hands/fins.

When Charles Darwin was exploring the Galapagos Islands, what was the religious belief about the origin of species?
Special creation-- each species was created specially by God
400
Similar species are grouped together into what is known as its.....
Genus
400
Divergent evolution produces organisms with what type of structures?
Homologous structures (Diverging from a common ancestor)
400
What was Charles Darwin's biggest question? (Hint: Alfred Wallace discovered this)
BONUS 100 POINTS: How did Wallace make this discovery? (2 ideas)
The mechanism of evolution-- how species come from other species
Bonus: Massive death + Variation

What is the predicted origin of the Galapagos Island finches? (Hint: Before speciation occurred)
One founder species came from the mainland and diverged into different species better suited for the islands of which they resided.

Provide an example of a change in a species that would result in reproductive isolation. (Hint: Think about mating behaviors)
Size of Darwin's finches
Pitch of mating song
Genetic differences
Coloring of males and females
Different times of breeding

What causes punctuated equilibrium to occur? (Hint: Punctuated equilibrium is when species are stable for a while then undergo rapid change)
Changes in the environment
Introduction of invasive species
