This image shows a cladogram. Which of the following best describes its purpose?
Shows organisms that do not show any evolutionary relationship.
It is used to show how each organism obtains its energy,
Shows the relationships between organisms based on characteristics.
Demonstrates how one organism evolved into another.
The type of evolution where closely related organisms that share a common ancestor evolve differences over time that results in speciation.

Extinction
Survival of the Fittest
If an organism does not have the adaptions needed to survive, its population will significantly decrease. If an organism has the necessary adaptations, then it will survive. This is known as which mechanism?
Survival of the Fittest
Extinction
Natural Selection
Competition
How an animal reacts to a change in their environment is a (a) adaption.

Divergent evolution
Natural Selection
How does evolution occur by natural selection occur?
Organisms will adapt in the moment to fit in with their environment to survive.
Organisms that are stronger will survive.
Organisms that are fit for their environment will survive and then pass down their traits to their offspring.
Organisms naturally select which adaptations they want to help them survive.
