Item EN026003: A population can differ from its ancestors because an environmental change could affect which individuals are more likely to survive and reproduce, based on which inherited traits they have.

A population is a group of individuals of the same species. Could a population living today differ from their ancestors from many generations ago? Why or why not?

  1. Yes, an environmental change could affect which individuals are more likely to survive and reproduce based on which inherited traits they have.
  2. Yes, an environmental change could cause individuals to make more use of certain inherited traits and pass down improved versions of these traits to their offspring.
  3. No, populations are all the same species and therefore have the same set of inherited traits no matter how many generations pass.
  4. No, the environment could not change enough over time for certain inherited traits to become more useful than others.
