Beginning in the 18th century, the concept of paleontology was established and was further developed in the 19th century. Paleontology is the study of prehistoric life, including organisms’ evolution and interactions with each other and the environment around them. It’s also the study of past fossil records of past geological periods and relationships between ancient and modern day species. Although it is a field of biology, it has also been associated with geology because of the attempt to learn about the Earth itself, not just its organisms. This field tries to explain causes rather than observing effects by conducting experiments. The use of paleontology was and still is an extremely important aspect in identifying organisms from the Paleozoic Era, a time period in which extinction and evolution collided with each other, helping to shape the biological world we know today.
The Paleozoic Era began about 542 million years ago and lasted for about 291 million years. It was divided into six parts known as the Cambrian, Ordovician, Silurian, Devonian, Carboniferous, and Permian. The oldest subdivision of the Paleozoic Era was the Cambrian period, which is also important to paleontologists because the rocks from this time are rich in fossils. During this period, evolution hit its peak, and for about 40 million years animal body plans were rapidly changing (Williams et al, 2007). Because of the sudden explosion of diversity during this period, it is sometimes referred to as the Cambrian radiation or Cambrian explosion. Many of the species that existed during this time period were marine organisms, mainly because at the beginning of the Cambrian period, life was entirely confined to the oceans. The evolution during this time period is...

...ndred million years, the remnants left behind by them tell paleontologists today a lot about the way they lived and how they adapted. With the understanding and capability to delve deeper into the meaning of a fossil, paleontologists can now attempt to unravel the unknown from past time periods. The ability to examine a fossil using calcite remains and DNA has improved throughout history due to our advances in technology and the knowledge gained from past discoveries. Conclusions can finally be drawn and proved about the existence of trilobites. What we know today about trilobites is published throughout the world, revealing their lifestyles, eating and reproduction patterns, relatives to this species, and how they managed to adapt to the environment around them. The mystery of the trilobite has finally filled a missing chapter in the novel to the Earth’s history.

Essay on Introduction to Trilobites

- Trilobites were arthropods with soft bodies and many legs that were positioned under a heavily calcified, segmented shell. They first appeared in the Early Cambrian Period (544 million years ago) and thrived through the Middle and Late Cambrian times before their extinction in the Ordovician period (495 million years ago). In their 49 million year existence, they diversified quickly and produced a fossil record that geologists refer to often. Arthropods are a phylum of hard-shelled creatures with multiple body segments and jointed legs....   [tags: Earth Science]

Prove the Existence of God Using Who Has the Idea of God Essay

- In this paper, I will explain how Descartes uses the existence of himself to prove the existence of God. The “idea of God is in my mind” is based on “I think, therefore I am”, so there is a question arises: “do I derive my existence. Why, from myself, or from my parents, or from whatever other things there are that are less perfect than God. For nothing more perfect than God, or even as perfect as God, can be thought or imagined.” (Descartes 32, 48) Descartes investigates his reasons to show that he, his parents and other causes cannot cause the existence of himself....   [tags: descartes, god's existence, idea of god]

René Descartes' Argument on the Existence of God Essay

- René Descartes' Argument on the Existence of God The problem with René Descartes' argument about the existence of God has to do with his rationalist deductive reasoning. Descartes deduces that truth about the existence of God lies within his idea of a perfect God and God's essence (as a perfect being who must exist in order to be perfect). A rationalist philosopher, Descartes discounts human knowledge as a product of our sensory data (our senses) but supports the epistemological stance that our knowledge is obtained through the reasoning processes of our own minds....   [tags: Philosophy God Existence Religion Essays]
