Article Review #3 The article “Ardipithecus ramidus: A New Kind of Ancestor: Ardipithecus Unveiled” written by Anna Gibbons, talks about how scientist learn many things about human evolution through artifacts of ancestors, DNA and bones. All of this helps reveals different things about our past and how we came to be. This article briefly mentions Lucy and it mainly focuses on the discovery of ardipithecus ramidus.
In the passage, the author claims that the Edmontosaurus migrated south in order to survive. However, the lecture refutes the view in the reading and argues that the arguments are not convincing. First of all, the passage establishes the view that Edmontosaurus diet drove them southward because there would have been no plants alive in the North Slope. By contrast, the professor in the lecture contends that Edmontosaur does not need to migrate to South to get food. Edmontosaur can get good quality of plants since it was 24 hours of sunshine during summer.
Home to a large Pleistocene fossil site, Saltville, Virginia has revolutionized modern archeology. The locality is especially significant because of unique interactions that took place between animals and humans 15,000 years ago. There has been recent evidence uncovered that Paleo-humans and the mammals in the surrounding Appalachian region interacted and the humans relied on the animals for survival. The deep history preserved in the land of Saltville reveals a past ecosystem that drew megafauna to its locality. The region, rich with life, is the second oldest known Pre-Clovis site in the Americas, marking its significance in history and archeology.
In The Sixth Extinction Kolbert’s tool of choice was narration. In essence, Kolbert uses narration to engage and connect with her audience and better convey her arguments and ideas in a manner that is easily understood. Kolbert’s central argument, though complex, can be boiled down to two key ideas. The first is that we are living in a geologic era known as the Anthropocene, a time frame characterized by humanity’s effect on the Earth.
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 of his place on the dinosaur’s extinction.
The number of sea otters a long time ago was 150,000–300 000, but unfortunately because of the fur trade, they were hunted a lot for their expensive fur between 1741 and 1911. The world population of sea otters fell to only to about 1 000–2 000. But later after all that, there was an international ban on sea otter hunting, and reintroducing sea otters into previously populated areas has helped to repopulate the species. Because of all the human help the species now occupies has about two-thirds from the population number they had before. The recovery of the sea otter is considered an important success in marine conservation.
Abha Joshi A.P. Environmental Science 08/07/15 The journey that is evolution has always been a deep interest of mine. The Earth and the evolution of its organism had grabbed my attention years ago. I’ve always found evolution as topic that has yet to be fully unraveled.
Finally, many may argue that human contributions such as hunting, poaching, etc. caused the decline of elk. Hunting did cause a decline in elk however the mass declination of elk came from the wolves being reintroduced. It incited fear into the elk as they would avoid certain areas to avoid the wolves territories. These areas had a better chance of vegetation to grow and animals and insects that wolves don’t eat, to migrate to those areas. The soil in the area were not disturbed as much as when the elks were there.
In the other hand, the speaker contends this by explaining that whales were declined because of the human hunting , orcas changed their diet to survive and because just of the sea mammals were available, human started to hunt sea mammals and cause the decline. Third, the author asserts that scientist believed that the pollution hypothesis could also the uneven pattern of otters decline. However, the professor opposes this pint by explaining that the uneven pattern is better explained by orcas predation theory. she added that it depends on whether the location is accessible by orcas or not, so because orcas are large, they can 't access the shallow region where sea otters have not
In the same way nature and humankinds are closely related and cannot be separated; or cannot deny the presence of one another. At the Anthropocene epoch, humankind seems to have control over the nature in some extent, despite that nature wait its time and respond how it’s been treated. At this epoch “human-kind has caused mass extinctions of the planet and animal species, polluted the oceans and altered the atmosphere” (Stromberg, np). Moreover in “The Mutant at Horn Creek” the author shows how humankind altered the natural world and its effect in the
Endless theories and hypothesis’ surround the disappearance of the dinosaur species. Comets, asteroids, disease, and volcanic eruptions are just some of the presumed causes of their extinction. Which one is to believe? In “Sex, Drugs, Disaster, and the Extinction of Dinosaurs,” Stephen Jay Gould presents three proposals for their extinction: Sex, Drugs, and Disasters. Gould explains the three theories on the extinction of dinosaurs by giving a biologic and scientific reason for each, with the purpose of showing that scientific discoveries come from testable theories.

In recent years, there has been an ongoing debate as to what caused the extinction of the Neanderthals around forty thousand years ago. Some researchers speculate that Neanderthals did not develop sufficient tools that would allow them to gather and hunt food efficiently while others speculate that early modern humans introduced deadly pathogens into Neanderthal populations which led to their extinction. However, researchers led by zooarchaeologist Jamie Hodgkins have found that frequent and lengthy glacial periods may have led to the extinction of the Neanderthals. They hypothesized that glacial periods may have reduced the quantity of prey that the Neanderthals hunted therefore they were unable to intake the required amount of food to survive.
For many years, Bigfoot has been, without a doubt, the most recognized mystery in all of North America. Bigfoot has reportedly been sighted thousands of times since the beginning of the 19th Century. Bigfoot is sometimes referred to as Sasquatch, an Indian name, which means “hairy giant”. There have been a lot of eyewitness’s testimonies that Bigfoot is this big gigantic ape covered in thick, brownish fur and towers in at eight feet tall and weighs over six hundred pounds. Many people believe that perhaps Bigfoot is a creature from another dimension or just some phenomenal creature.
