The Cambrian Explosion: Proof of ID? Essay -- Biology Biological Essay

The Cambrian Explosion Proof of ID? In our studies of Intelligent program (ID) theory and Creation Science, I found little information that gravely challenged the theory of evolution. However, there was one event that appeared to defy the logic of Darwinian gradualism the Cambrian Explosion. This event was rangeed by ID theorists as proof of design--something which science is ineffectual to account for. Unfortunately for ID proponents, this is not the case. There are several scientific explanations for the Cambrian Explosion. I will give an account of the Cambrian Explosion, present the ID arguments relating to it, and give some scientific explanations of the event. The so called Cambrian Explosion was a period of rapid diversification of animal life on earth. It took brand approximately 550 million years ago (it bears mentioning that estimations of geological time this distant back are fairly rough). There is some dispute everywhere j ust how long the explosion lasted. Scientists traditionally proposed a duration of nearly 30 million years (Ward and Brownlee, p. 137). However, some new evidence cool in Russia may indicate a much shorter timescale- 5 to 10 million years (Kerr 1993, p. 1274). The truly unique thing about the Cambrian Explosion was the rapid generation of extremely diverse life forms. smell is generally classified with a system going from broad to item description. Kingdom, the broadest classification, describes whether a given specimen is plant, animal, fungi, protist, or moneran. The next most particular indicator is phylum. The phyla indicate the body design of a taxonomical specimen. Humans, along with all other species that poses a spinal ... ...ore Explosive. Science, New Series leger 261, Issue 5126.
