Living fossil Essays

Nathaniel Hawthorne and William Faulkner's short stories "Young Goodman Brown" and "A Rose for Emily" use morals of the time period to tell a story and teach a lesson. Both short stories are dark and gloomy accounts of the main characters' station in society and their self-imposed isolation. Hawthorn and Faulkner use the characters to describe society as judgmental and hypocritical of one another, and the moral of the story is used to teach the reader a life lesson about judging others. Both stories

Riversleigh Fossil Site, Australia Geological History Riversleigh covers an area of approximately 80 square kilometres and is located 250 km north-west of Mt Isa. Riversleigh is Australia’s most famous fossil site and fossils were first discovered in the area in 1901. The fossils document the evolution and changes of Australia's terrestrial fauna and ecosystems. The last remnant of the supercontinent Gondwanaland finally separated into Australia and Antarctica between 30 and 40 million years

Have you ever heard of fossils? Animals have been changing ever since the beginning of living things. The animals have to adapt to their environment, like the whale. The whale used to have feet, we know this because of their fossils, and since they swam more than they walked on land, they are losing their legs and feet over time. This shows that animals change over time, and therefore evolution is real. Evolution is change over time, and that is what is happening to all animals. To show you that

Concept 25.2 – The fossil record documents the history of life • The fossil record is what gives us access to a view of what the world was like long ago o We have a sight of how life has evolved over the course of billions of years A. The Fossil Record • Fossils are primarily found in sedimentary rock • Strata are sedimentary rock layers in which fossils have amassed o The fossil record is based on the sequence of this • There are also other types of fossils o Amber and ice • The fossil record is evidence

and sells the shells that she finds. Mary Anning was a young woman born to a working class family that lived in Lyme Regis, a small seaside town in England. She grew up helping her father comb the beaches for fossils they would sell to tourists. Even after her father died, Mary kept up the fossil collecting practice in order to sustain her mother and brother. But what started out as a means of survival for the Annings turned out to impact the world of paleontology in the early 19th century, though Mary

What are fossils? “Fossils are the remains or impression of a prehistoric organism or object preserved in petrified form or as a mold or cast in a rock,” according to Encyclopedia.com. Some examples of fossils are a mold of a seashell in a rock or maybe the remains of a dinosaur such a tyrannosaurus rex. A mold of a seashell in a rock may not seem all that exciting, but it can tell us a whole lot about the past. Simply put, through fossils we get see what species existed on earth and when they

period. The Cambrian period had this big explosion that leads to new organisms on the land. Beginning around 542 million years ago in the Cambrian Period, during this period most major animal phyla appeared, it was determined by the fossil record. This period lasted about 53 million

A ‘living fossil’ has been determined as ‘an organism that has remained essentially unchanged from earlier geological times and who’s close relatives are usually extinct’ (Merriam-Webster, 1859). This is suggesting that the Duck-billed Platypus, more commonly known as the Platypus, would still be in its primitive form and have similar characteristics to it ancestors. Anyone looking at the Platypus can identify its abnormalities as it is so distinctively unique in the animal kingdom. Its name on its

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

Horseshoe crabs are an ancient marine chelicerates, identified as the Class Merostomata and Order Xiphosura. The animals are identified by the having appendages around their middle of the mouth and their swimming legs at their end of their body. They are in close linkage with trilobites and arachnids which are spiders and scorpions. Amazingly, they are

feathers. In Jurassic park the velociraptors are shown as raptors that are bigger than humans and have a rough scaly skin. If you look at the arm bones of Velociraptor you can see a row of bumps, identical in size and shape to the quill knobs of living birds: the anchor points for big wing feathers...” These are very similar structures found on both birds. It is not for certain what these feathers would have looked

each of the following provide evidence supporting evolution. Provide at least one specific example of each. a. Transitional fossils: Transitional fossils are the missing links between animals we see today and their ancestors. During evolution, many animals developed adaptations and evolved over time to be better suited for life on Earth. An example of a transitional fossil is Pakicetus, which is an early ancestor to today’s whales. (Berkeley) b. Biogeography: Biogeography is the study of geographic

of what fossils tell us about the ecologies of the past, about evolution, and about our place, as humans, in the world. Paleontology incorporates knowledge from various fields, even computer science, to understand the processes that have led to the origination and eventual destruction of the different types of organisms. Paleontology is essential for working out the history of the earth. Another application of paleontology is the use of fossils in the oil

The earth is dated to be around 4.6 billion years old and the existence of life is at least 3.5 billion years. In order to understand our history of life and primate and human evolution, it is vital to place each fossil in chronological sequence and know how old it is. There are several methods that scientists may use to get a direct date of fossilized remains which are radiocarbon, U-series, electron spin resonance, and amino acid racemization. These dating techniques are essential for understanding

the fossil record. Pre-Cambrian organisms consisted of prokaryotes, eukaryotes, bacteria and ediacaran life forms. In less than 5 million years, most of the basic body plans that we observe in modern groups appeared; cnidarians, molluscs, arthropods, echinoderms and the chordates all came on to the scene. This explosion directly conflicts Darwin’s theory of natural selection acting on random variation, the Cambrian fossil record contradicts the empirical expectations of

Biodiversity in simple terms means living things. This relates to megafauna because they once were living things that roamed around the planet. There were different species of megafauna living in different parts of the world which relates to the diversity of megafauna. The audience that would be interested in my brick would be anyone who has an interest in megafauna. For example historians, they study events or objects in the past and megafauna is an animal that is famous for its history. There

Fossils are the preserved remains of plants and animals. Fossils are usually found in the earth’s crust in either a frozen form, petrified form, or trapped in a substance like tar or amber. An example of fossils are the bones of dinosaurs that have gone extinct after a massive meteorite impacted the earth at the end of the cretaceous period. Another type of fossil is a trace fossil. These fossils are not the fossilized organism itself but they are the indirect evidence that the organism had once

1. Humanization vs. Hominization: a. Compare and contrast Lamarck’s and Darwin’s explanation of the process of evolution of the species. [Criterion A] Lamarck believed that if your body changed in order to adapt then those features would be inherited into your biological children. Darwin believed that all species develop through a process of natural selection called the “survival of the fittest” which states that some traits that help organisms compete, survive and reproduce are most likely going

Title Researchers and scientists have constructed extensive research on dinosaur’s extinction. Speculation instead of real evidence seems common in most theories about the dinosaurs’ extinction. However, Jay Gould’s essay “Sex, Drugs, and the Extinction of Dinosaurs” is the complete opposite of speculation over evidence. Rather, Gould uses the mix of persuasive techniques, such as rhetorical questions, logos, along with profound evidence to not only disapprove of other theories but convince readers
