Mechanisms of Evolution
100
This man went to the Galapagos islands and was the first to suggest a mechanism for evolution based on scientific evidence
Who is Charles Darwin
100
This is the biological definition of evolution
What is a change in the genetic composition of a population over time
100

This is the level of life that natural selection acts on (individual, population, community)

What is an individual

100
These are structures that once were fully functional in a species' ancestor, but are no longer functional and are reduced in the species
What is vestigial structures
100

This mechanism is when mates are chosen for specific traits.

What is Non-Random mating?

200
He studied geographic isolation patterns.

Who is Darwin?

200

This is the type of isolation that happens when a species cannot reproduce because they have lived on separate islands for a long period of time.

What is geographic isolation?

200

A trait that enables an organism to survive and reproduce in their environment 

What is adaptation

200
This is required in order for two or more structures to be considered homologous
What is a common ancestor that had that particular structure
200

A DNA rearrangement that helps an organism survive is called this

What is mutation?

300
This man proposed the idea that organisms can pass down acquired traits to offspring.
Who is Lamarck
300
This is one type of limiting factor
What is shelter, food, predators, environment/climate
300

True or false. It is better to have more genetic variability in a population.

True

300
These are the 4 main pieces of evidence that support the theory of evolution
What is fossil record, comparative anatomy, biogeography, direct observations
300

True or false. All traits can be passed down through genetics.

False.

400

Proposed and was debunked, that animals can stretch their necks for food.

Who is Lamark?

400
This is the type of genetic drift that occurs when a few members from a population start a new population
What is the founder effect
400

This is the type of selection when the extreme form is selected, while the intermediate form is selected against.

What is directional selection?

400
An owl wing and a dragonfly wing are considered to be these kinds of structures and this is the explanation
What is analogous and their wings do not share a common ancestor
400

This mechanism is when species enter the population, contributing to a different gene pool.

What is gene flow?

500
These are the type of birds that Darwin observed had different beaks
What is finches
500
This is the type of genetic drift where a population undergoes a reduction and there can be a decrease in the diversity of the gene pool.
What is the bottleneck effect
500
This is the type of selection when the intermediate form is selected against, while the two extremes are selected for.
What is disruptive selection
500
This is the type of evidence that uses preserved remains or traces of ancient organisms to help support the change over time in organisms
What is the fossil record
500

This mechanism is when traits are inherited because they are better suited to the environment.

What is natural selection?
