    Explain the concepts of phyletic gradualism and punctuated equilibrium

    Phyletic gradualism was proposed by Charles Darwin and includes the concept of Natural Selection. As the name phyletic gradualism implies, natural selection gradually changes various attributes of a species by favoring more fit individuals who breed more and perpetuate the genes that support the survival of the species. Consequently, less fit individuals are removed from the breeding stock of the species. Evolutionary changes are continually occurring, and the traits which either increase the survival of the species or are not detrimental will persist in the population over time.

    Punctuated equilibrium models species evolution in a different manner. Species undergo very little evolution for extended periods before evolving rapidly over a shorter period. ...
