Theories and Theory of Evolution

Write 3–4 pages on the following (not including the title and reference pages):

• Explain the concepts of phyletic gradualism and punctuated equilibrium.
• What predictions about the fossil record does punctuated equilibrium make?
• In this model, what are the processes that produce rapid evolution? Which evolutionary factors are responsible for the periods of relative stasis?
• Patterns of punctuated equilibrium have been observed in some cases, but the debate between punctuated equilibrium and phyletic gradualism continues and provides interesting areas of research. Based on your research into the scientific process, what evidence do we see today that supports a long history of life on the planet?
• What evidence do we see that supports evolution by gradual change?
• What evidence do we see that supports the concept of punctuated equilibrium?
