Putting Evolution in Context:

"It is interesting to contemplate an entangled bank, clothed with many plants of many kinds, darwinwith birds singing on the bushes, with various insects flitting about, and with worms crawling through the damp earth, and to reflect that these elaborately constructed forms, so different from each other, and dependent on each other in so complex a manner, have all been produced by laws acting around us. These laws, taken in the largest sense, being Growth with Reproduction; inheritance which is almost implied by reproduction; Variability from the indirect and direct action of the external conditions of life, and from use and disuse; a Ratio of Increase so high as to lead to a Struggle for Life, and as a consequence to Natural Selection, entailing Divergence of Character and the Extinction of less-improved forms. Thus, from the war of nature, from famine and death, the most exalted object which we are capable of conceiving, namely, the production of the higher animals, directly follows. There is grandeur in this view of life, with its several powers, having been originally breathed into a few forms or into one; and that, whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being, evolved.  "
                                                               -Charles Darwin (The Origin of the Species, 1859)

    In order to understand and appricate the current theory of evolution, one must first understand the history behind this theory.  The links on the left are designed to prep you for your journey by providing you with a breif background on the theory of evolution and the mechanisms by which it operates.  If you already feel like this is background you posess then click on the Chesapeake Bay: An Evolutionary Study in Geologic Time link to return to the main menu, then click the Field Study: Chesapeake Bay link in order to examine the procedures and data collected and examined by Kelley in her study of mollusk evolution.
