100
The image above shows this type of speciation.
What is directional?
100
The picture below shows mice who have variations in what characteristic?
What is fur color?
100
The oldests fossils are found in the rock layers located here.
What is deeper down?
100
The human tailbone is an example of this unused structure.
What is a vestigial structure?
100
This is the name of the boat that Darwin sailed on to the Galapagos islands.
What is The Beagle?
200
The image below shows this type of speciation.
What is disruptive?
200
The picture below represents this principle of natural selection.
What is overproduction?
200
This is the best estimate for the age of the Earth.
What is 4.6 billion years?
200
The archaeopteryx fossil pictured below is known as this type of fossil.
What is a transitional fossil?
200
Darwin noticed variations in these animals on the Galapagos islands.
What are finches OR tortoises?
300
A population of finches moves to an island where their preferred food source (medium sized seeds) is not available. There are only tiny seeds and giant seeds. This type of selection is most likely to occur.
What is disruptive selection?
300
Natural selection is based on the fact that there are genetic variations between individuals in a population. The variations can result from these changes to the DNA.
What are mutations?
300
This form of life was the most recent of the vertebrates to evolve.
What are mammals?
300
Humans did not evolve from monkeys. Rather, they share this type of relative.
What is a common ancestor?
300
The image below shows an example of this type of selection.
What is artificial selection?
400
A population of finches moves to an island where their preferred food source (tiny seeds) is not available. There are only medium-sized seeds. This type of selection is most likely to occur.
What is directional selection?
400
The members of a population who have variations that help them survive in their environment are called this.
What are the fittest?
400
In Earth’s history, there have been this many major extinctions.
What is five?
400
When comparing these developmental forms of animals, we see that many are very similar.
What are embryos?
400
Some bacteria species have evolved this trait, which makes them hard to treat and kill.
What is antibiotic resistance?
500
95% of human babies are born weighing between 5.5 lbs and 11 lbs. This is an example of this type of selection.
What is stabilizing selection?
500
In order for a population to evolve, individuals who are more fit for the environment must also do this.
What is reproduce more than the other individuals.
500
The current geologic epoch is called this due to the impact of humans.
What is the anthropocene?
500
The similarities of this molecule between species can be used to determine how closely related they are.
What is DNA OR protein?
500
A mutation causes some humans to develop better eyesight, allowing them to see clearly at night. This mutation will increase in the population over time only if this is true.
What is it increases the fitness of the humans for their environment.
