We are the least genetically diverse primates because our total population dropped to around 10,000 individuals around 80 centuries ago. This is an example of what?
bottleneck effect
extinction
founder effect
gene flow
Darwin's finches is NOT an example of...

vertebrae
tetrapod
What trait do only humans have on this cladogram?
amniotic egg
bipedal
vertebrae
tetrapod
Who are prosimians most closely related to?

Komodo dragons fighting over the right to mate with a female is an example of what?
structural adaptation
physiological adaptation
behavioral adaptation
Mutations are a change in...

tRNA
A fossil of an extinct dinosaur is found and the anatomy of the fossil shows similarities to that of a bird. What could this mean?
This is purely by chance and isn't significant.
The extinct dinosaur and the modern bird share a common ancestor.
All dinosaurs evolved into birds and that's why there aren't any dinosaurs alive today.
Dinosaurs chose to fly and evolved into birds to escape predation and capture food.
Two organisms that are closely related would have...
very similar DNA sequences
exactly the same DNA sequence
no proteins in common
completely different DNA sequences
Which of the following are examples of evidence for evolution?
Fossils
Structures (anatomy)
Genetics/DNA
Generations of a species that are farther apart from each other look the most different.
True
False
The fossil record provides evidence that...
Fossils cannot be dated
All species were formed during Earth's formation and have changed little since then
Fossilized species have no connection to today's species
Older species gave rise to more recent species
Which CAN evolve?
Individuals
Population
What process is being shown here?
Variation
Natural selection
Selective breeding
Genetic drift
Why is the mouse population changing over time?
The light mice can reproduce more successfully than the dark mice
The hawks eat more light mice because they can see the light mice more easily
The hawks eat more dark mice because they can see the dark mice more easily
The hawks eat more dark mice because they taste better
How will the mouse population change over time?
It won't change
The dark allele will become more common
The light allele will become more common
We don't have enough information to make that assumption
