Station 1 : Evolution Theory of Natural Selection: Use the answers in the bank, to fill in the blanks Answer Bank a. Overproduction b. The spread of an adaptation throughout new generations. c.

It is based upon 4 principles: i. Producing more offspring than are likely to survive. ii. Heritable differences in an individual from those of the same population. iii.

A characteristic that allows an individual to better survive in their environment over others of the same population. Evidence for Evolution: Answer the following questions 2.
