What is an example of a neutral mutation?

• a disease

• a change in eye color

• lactose intolerance

Why are some traits more common in some populations?

• It is random

• organims choose their traits

• common traits are ussualy adaptive and help organisms survive and reproduce

• organisms traits change all the time

Mutations are important because they bring about

• death of the organism in which they develop

• genetic variation needed for a population to evolve

• benefits for the individual, not for the population

• Hardey-Weinberg equilibrium within a population

What is the advantage of having different shaped beaks?

• To look different from other species.

Why would a population with a large amount of genetic variation be more likely to survive a severe climate change in its environment?

• Individuals will only create offspring well-suited to the climate change

• The individuals would produce more offspring

• Individuals better suited to the new climate will help less-suited individuals survive

• Some individuals will posses traits better suited to the new climate and be more likely to pass them on

Do organisms "decide" to evolve and change?

• Yes, they know they need to change to survive 

• No, they change because of natural selection
