One of the main sources that paleontologists use to discover hidden secrets about the past is through studying fossils. Geologists, paleontologists, biologists, and other scientists study fossils in order to uncover facts about the different species and organisms that roamed the Earth up to 3 billion years ago. Using this knowledge, scientists have learned more about the geological processes that continually happen today, as well as climate changes from the past and present, the origination and extinction

Have you ever wondered what the big deal is about fossils? Fossils are preserved bones. There are all sorts of fossils, dinosaurs, mammals, amphibians, fish, reptiles, birds, just to name a few. Did you know that the first dinosaur fossil was found in 1676? But there are relatively few found in the United States compared to what there is left to find. But we have some exciting news! There may be some fossils in your area! We are planning a dig near you. We just need your support! We believe that

ife began on earth about 3.5 to 4 billion years ago, since then it has evolved and flourished. Within the kingdom Animalia, it alone consists of 35 phyla. Two of which are Onychophora and Annelida. Onychophora are believed to be a possible link between two phylums of Annelids and Arthropods as it carries characteristics of both groups. This essay seeks to compare and contrast between the earthworms from phylum Annelida and the velvet worms from phylum Onychophora. Internal Velvet worms and earthworms

insects don't grow). So crustaceans, trilobites, and so on may drop a dozen or more outer skeletons into the fossil record before they finally die. Molting may act as a bias suggesting that a species was MORE abundant than it was in reality. Size Large fossils are easier to see Large shells or bones are stronger, so less likely to be destroyed and more likely to be preserved. Large fossils are more likely to be found sticking out of the rock. This is not the same bias as the first one, but it is

weeks assignment I will be discussing and explaining a few things that have to due with evolution. In the first segment I will be talking about phyletic gradualism and punctuated equilibrium. In the second part of the paper I will be discussing fossil records and the connection they have with punctuated equilibrium. Finally I will be talking about rapid evolution and relative stasis. Explain the concepts of phyletic gradualism and punctuated equilibrium. Phyletic gradualism is a model of

to speciation events.” Punctuated equilibrium predicts that the fossil record at any one site is unlikely to record the process of speciation. If a site records that the ancestral species lived there, the new species would probably be evolving somewhere else. The small size of the isolated population which is evolving into a new species reduces the odds that any of its members will be fossilized. The new species will only leave fossils at the same site as the old one if it becomes successful enough

combinations of specific source that tell the what scientist have documented and dated there sources. These are examples of why some assume the age of the earth is a billion years old. One big scientists believer was James Hutton studied rocks and fossils and believed the they made millions of years ago. But with every study he had to make people understand the laws of nature and the different events that life has formed within the earth. There are many reason we can say the world was made thousands

In my paper I will be talking about article The Origin of Old-Earth Geology and its Ramifications for life in the 21st century by Terry Mortenson. I will discussing the main points of the article along with the strengths and weaknesses. This article is a breakdown of a huge debate that has been going on for years. As I mention before this article is based on a debate that has been occurring for years. It is just another argument between the theories of the young- earth and Old-earth. A lot of the
