  3. adaptive radiation.
  4. mutation.
Grade 7 Evolution
In the theory of natural selection, species are most likely to survive if they

  1. Evolution Over Time
  2. Darwin and the HMS Beagle
  3. The Origin of Species
  4. The Origin of Evolution

Grade 7 Evolution
Which statement is true about DNA and evolution?
