Quiz #2 Evolution

Where the better adapted organisms survive to pass traits along to offspring.

• Evolution
• Natural Selection
• Extinction
• Artifical Selection

Why are advantageous traits more likely to be passed onto offspring?

• Because they are more likely to survive and reproduce.
• Because they come from dominant alleles.
• Because they come from recessive alleles.
• Because the trait is an acquired phenotype.

Do organisms "decide" to evolve and change?

• Yes, they know they need to change to survive 
• No, they change because of natural selection

Which of the following best illustrates natural selection?

• An organism with favorable genetic variations will tend to survive and breed successfully.

• A population monopolizes all of the resources in its habitat, forcing other species to migrate.

• A community whose members work together utilizing all existing resources and migratory routes.

• The largest organisms in a species receive the only breeding opportunities.

Mistakes or changes that occur int he DNA sequence are called....

• adatations
• Darwinism
• mutations
• natural selection

The preserved remains or physical evidence of an organism that lived in the past are called...

• evolutionary features
• fossils
• mutations
• variations

Which would NOT be considered a fossil?

• bones buried deep in the earth
• footprints harened in  mud or rocks
• imprints left in rocks
• stories passed down from generation to generation

This scientist came up with the idea of natural selection.

• Jean Baptiste Lamarck
• Gregor Mendel
• Charles Darwin
• Thomas Malthus

What do we call a change in a species over time?

• Adaptation

• Evolution

• Extinction

• Environmental influences

Why is biodiversity so important?

• Because all species depend on each other to survive, so if one becomes extinct another species that relies on it could go extinct as well
• Because it’s better to have only one variation of each species.
• Because it better to only have a few species on Earth.
• Honestly, I have no idea what biodiversity is!
