Evolution/Classification

Which of the following is NOT part of Darwin's theory of evolution by natural selection?

• Variations exist within populations

• Some variations are more advantageous for survival and reproduction than others

• Organisms produce just enough offspring that can survive.

• Over time, individuals with more advantageous traits produce more offspring; and their genes make up more of the population.
