The process of how organisms acquire adaptations over time is called this.
What is evolution?
100
This is an inherited trait that helps an organism survive.
What is an adaptation?
100
Results in changes in the inherited characteristics of a population.
What is natural selection?
100
These have different mature forms but develop from the same embryonic tissue.
What are homologous structures?
100
The finches Darwin found on the Galapagos Islands are examples of this pattern of evolution.
What is adaptive radiation?
200
Proposed a hypothesis to explain how living things change over time.
Who is Charles Darwin?
200
Members of each species compete regularly for food and other necessary resources.
What is a the struggle for existence?
200
Living species have descended with changes over time from other species.
What is descent with modification?
200
The appendix in humans or legs in skinks are examples of this.
What are vestigial organs?
200
The finches Darwin found on the Galapagos Islands have a common ancestor they adapted to fit the different island ecosystems.
What is divergent evolution?
300
These two scientists explained that the Earth and it's features have been shaped by geological forces acting over long periods of time.
Who are Hutton and Lyell?

fitness
What is the ability of an individual to survive and reproduce in its specific environment?
300
The climate of a certain area is cold, and snow is found on the ground most of the year. Equal numbers of two populations of rabbits are introduced into this climate by a group of scientists. One of the populations is brown and the other is white. Over several generations, this will happen.
What is there will be more white rabbits than brown rabbits?
300
Darwin argued that this provided evidence that living things have been changing over a long period of time.
What is the fossil record?
300
Sharks, dolphins and penguins share similar characteristics that help them live in water.
What is convergent evolution?
400
Jean-Baptiste Lamarck.
Who proposed that organisms acquired or lost traits during their lifetime by selective use or disuse of organs?
400
A species of snail living in the same population displays differences in shell stripe patterns.
What is genetic variation?
400
What is artificial selection?
400
This picture is comparing these.
What are homologous structures?
400
Coevolution
What is the process by which two species evolve in response to changes in each other over time?
500
Predicted that the human population will grow faster than the space and food supplies needed to sustain it

500
This consists of all genes, including all the different alleles, that are present in a population.
What is a gene pool?
500
This is graph is an example of it.
What is disruptive selection?
500
In early stages of development, chickens, turtles and rats look similar, providing this kind of evidence.
What is comparative embryology?
500
These are two different explanations for the rate of evolution.
