Theory of Natural Selection: Use the answers in the bank, to fill in the blanks
1. Natural selection is…A process where those with beneficial adaptations have a better chance for survival. a. It is based upon 4 principles:
i. A Producing more offspring than are likely to survive. ii. C Heritable differences in an individual from those of the same population. iii. F The ability of a trait to be inherited and passed down from one generation to the next. iv. E A characteristic that allows an individual to better survive in their environment over others of
the same population.
