Evolution

Question 1

What is natural selection?

Answer 1

When an organism has the best traits fit for it’s environment (survival of the fittest: most capable of staying alive)

• can change depending on it’s environment (adaptation)

Question 2

What are the two ways that new characteristics can be formed in an organism?

Answer 2

1. Mutation: A mistake happens while copying the DNA, the organism gets a trait other than the trait it was supposed to have
2. Adaptation: An organism starts to change based on it’s environments survival requirements; that change becomes permanent

Question 3

Can the change in an organisms DNA get passed to it’s offspring?

Answer 3

Yes, it’s possible if the change becomes permanent (it’s worth noting not all adaptations create permanent changes)
