Life on Planet Earth

Paper Summary:

This paper is an examination of life on Earth from its humble beginnings on through the remarkably fecund Cambrian period. Among other things, this paper looks at the Earth's own unlikely beginning, the slow development of life on its surface and the perils it faces. Of special interest, the paper devotes a great deal of time to possible explanations for the recrudescence that took place during the Cambrain period.

From the Paper:

"The origins of life on earth have fascinated and engrossed scientists for generations. This fascination, of course, should not be surprising: as human beings, we have an instinctive need to know our past - perhaps because knowing our past gives our lives meaning and context and informs our present and future. Whatever the case may be, the study of life's origins has long been one of the chief pursuits of the scientific community. With this in mind, the following chapter will examine the history of life on planet Earth from the earliest days of our planet, on through the period in which the first simple, multi-cellular organisms emerged, to the "Cambrian Explosion" and the marvelous profusion of life that it created.
