Extinction Happens 1 2 3 Thomas Henry De La Beche (1796‐1855), sketch of life in ancient Dorset, 1830 4 5 A few unfortunate but widely-recognized facts about the history of science (and society and religion and...) • rich, old, straight* white guys are (mostly) everywhere • the participation of women was (in many cases) actively discouraged or discounted • the participation of non-white guys and all poor guys was (in most cases) actively discouraged and/or discounted • some aspects of scientific

Fossils are among the most highly prized natural objects in the world. Paleontology has its roots in two subjects: geology and biology. Geology and paleontology are intimately linked. In geology, fossils are important in piercing together rock successions from the same time interval across the globe, and in interpreting the nature of ancient sedimentary environments. Fossils are also unrivalled as stratigraphical tool. The process of evolution acts as an irreversible clock in which the appearance

One of the evidence of evolution is by studying the fossil layer which is also known as Paleontology . Fossils normally contains remains or traces of organism from the past and by studying them we were able discovered the organism from the past and how they evolved across a geological time and it could be traced back to as far as 3.48 billon years ago(Nora Noffke 2013). Horse teeth are often preserved because they are important evidence that show the macroevolution of the Equidae as horse teeth has

in the area are said to be the result of a heavy presence of algae. The toxic gases omitted from the volcanic crater are thought to be the reason for such a high number of land animals having been fossilized. It wasn’t until 1875 that the first fossil, a crocodile, had been discovered. Since then, numerous fish and sea creatures, thirty one plant species, 45 mammals, and 43 species of bird have been discovered. Some even had stomach contents and tissue still intact. There is no doubt that the area

Introduction: Every aspect of our surroundings, everything we witnessed at the two sites that we visited and everything geologically related can be tied together with a few simple concepts. A central component of those simple concepts is known as the Wilson Cycle. The Wilson Cycle has a massive impact on not only the two sites that we visited, but literally everywhere around the world. By understanding the principles of the Wilson Cycle, we are able to unearth details about a location such as

occurred in rapid periods of time or that a designer intervened during different times to modify or create organisms. The controversial debate of punctuated equilibrium and phyletic gradualism still exists, but the interesting research continues with fossil records, patterns of punctuated equilibrium, and maybe even more with the use of innovations of today. It is safe to say that scientists agree there is two models of growth which theorizes evolution of species can emerge. A species can change

became a water creature due to not have enough food in its land environment. “It's long been assumed that marine mammals in the pinniped group – seals, sea lions and walrus – evolved from a land-based common ancestor, but until now, no definitive fossil evidence had materialized” (Harmon, 2009). The animal would have had four legs that would have become webbed after its transfer to water. Its adaptation would have allowed it to survive under water for longer periods as well. The creature would

decayed. The decaying matter was buried by sand and clay. The pressure caused by the weight of the decaying matter formed fossils and coal. The main type of rock found in Mill Creek Park is sedimentary. Sandstone cliffs are visible throughout the park as well as shale. The sandstone shows signs of weathering as yellow and reddish brown streaks are visible. Fossils of plant life can found near Lanterman Bridge. Coal and iron ore are also present in the park. The effects of the Ice

Horseshoe crabs are marine living fossils, probably traced back to 485 million years ago. There are two horseshoe crab species found in Hong Kong. Horseshoe crabs are an ancient marine chelicerates, identified as the Class Merostomata, Order Xiphosura. The animals are identified by the possession of appendages around their ventral mouth and their swimming legs at their distal end. They have closer lineages with trilobites and arachnids such as spiders and scorpions instead of the "real" crabs which

Interview Paper The creationism-evolution debate has been on since men exist. It has a long history. In response to conclusions developed by evolution scientists, creationism scientists usually refute the legitimacy of their ideas that are opposite to the text of the Bible. There are many aspects that people would argue about. In this course, we focus on the origin of life. The purpose of this course is to provide a firm foundation for a consistent biblical worldview. After this course, we are
