Natural Selection

The change over time in populations of related species.

• biological evolution
• transition
• variation
• adaptation

These cause variations.

• mutations
• adaptations
• a desire to change
• injuries

A slight physical difference in an inherited trait between individual members of the same species.

• variations
• adapatations
• homologous structures
• analogous structures

An inherited trait that increases an organism's chance of surviving and reproducing.

• variation
• adaptation
• vestigial structure
• mutation

The discovery of DNA and genes proved that

• Darwin was wrong
• mutations create variations and come from specific genes for a trait

• we are all the same species
• bats and butterflies have a very close common ancestor

Adaptations can be:

• camouflage

• ability to survive cold weather

• hunting skills

• all of the above

A yellow morph and green morph of an insect lives in the rainforest canopy. You would expect:

• the green population to increase and the yellow to decrease

• both populations should stay the same

• both populations will increase

• the green population to decrease and the yellow to increaseThis is a wrong answer

How do you "win" at natural selection?

• survive

• go extinct

• survive & reproduce

Survival of the best adapted (most fit) and Evolution were proposed by what scientist?

• Charles Darwin
• Albert Einstein
• Steven Hawking
• Isaac Newton

When every organism of a species has died.

• Evolution
• Natural Selection
• Extinction
• Artificial Selection
