Evolution is a natural consequence of a any variety  being selected by any selection process that affects  the number of a variants represented over time Variety  occurs at many levels in biology: In our discussion of evolution, we will focus on two  types of variety: Macroevolution  -differences that come about that  distinguish one type (species) from another Microevolution  - differences that come about that  distinguish one individual of the same type from  another

Variety expressed in biology is the result of two major  influences : 1. variety in an organism’s genome (nature)- define its  heritable traits Heritable traits  - traits that are passed on from parent  and/or to offspring during reproduction (DNA) 2. Variety in an organism’s environment          (nurture) The interplay between an organism’s genome and its  environment ultimately determine the viability of the  organism during its lifetime
