In order to survive the individuals within the specie must be adapted to, or adapt to, the environment in which they exist. B. An individual or specie that is not adapted to the environment in which it currently exists will die. C. Characteristics of an individual within a specie are determined by genetic material in interaction with the environment D. In species that reproduce sexually, genes are inherited from parents which results in genetic diversity and diversity of characteristics within a specie (phenotypic diversity) E. Occasionally mistakes are made when genetic material duplicates itself during the reproductive process. These mistakes or mutations in the genotype result in changes or deviations from the norm of the specie expressed in the phenotype of the individual F. Almost all mutations result in phenotypes that are unable to survive, however some mutations result in phenotypes that are better adapted to the
