Question

1. part a: select the four mechanisms of evolution.

mark all that apply
□ new individuals moving to a population
□ adaptation
□ random events
□ environment selecting for certain traits
□ random changes to dna that is passed on
□ some individuals growing stronger due to intense exercise
□ new mutations arise in the body cells not the sex cells

Explanation:

The four mechanisms of evolution are natural selection, genetic drift, gene flow, and mutation. "New individuals moving to a population" is gene flow; "Random events" is genetic drift; "Environment selecting for certain traits" is natural selection; "Random changes to DNA that is passed on" is heritable mutation. Adaptation is a result of evolution, not a mechanism. Acquired traits (e.g., exercise strength) and somatic mutations are not heritable and not evolutionary mechanisms.

Answer:

• New individuals moving to a population
• Random events
• Environment selecting for certain traits
• Random changes to DNA that is passed on
