I need about 3 pages to:
Explain the concepts of phyletic gradualism and punctuated equilibrium.
What are some presumptions about fossil records related to PE?
What are some events that facilitate rapid evolution?
Evidence that supports the long history of life on this planet.
What evidence do we have today that supports evolution by gradual change?
What evidence do we have today that supports punctuated equilibrium?
I have attached the response to your posting in a Microsoft Word document.
Please let me know if you have any further questions.
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. ...
The Phyletic gradualism and punctuated equilibrium is examined.
