5 True/False Questions

1. disruptive selection → natural selection that favors individuals with either extreme of a trait

   True        False

2. behavorial isolation → two or more species reproduce at different times

   True        False

3. speciation → a change or alteration in form or qualities

   True        False

4. puncuated equilibrium → a state of balance

   True        False

5. directional selection → occurs when natural selection favors one of the extreme variations of a trait

   True        False
