Ice Age Extinctions Of The Megafauna
1,675 wordsICE AGE EXTINCTIONS OF THE MEGAFAUNA During the last Ice Age before humans arrived, the North American continent belonged to various forms of enormous, fantastic creatures. By the end of the Ice Age, most of these large animals had become extinct. Numerous attempts have been made to explain the disappearance of these animals, but there has yet to be a consensus. Among the theories that have been debated, two are predominant. They are the climatic change theory, and the overkill theory. The clima...

Million Years Ago Radio And Television
1,529 wordsMedia nowadays is considered a window for learning and is also considered to be our main window to the world. Media has evolved from simple text in papers, to voices in radios, to voices with pictures in television and movies, to the very broad and information packed Internet. But as we all know, media has changed and evolved since then. Media then was primarily used to deliver news across the town and to beef up the people with the information they need for their everyday life. Then, newspaper ...

Billion Years Ago Solar System
2,233 words... alvarez's case, and see if it was flawed. This job was turning out to be more fun than I had expected. On my second reading of Alvarez's letter, I found it particularly dubious that the Cretaceous and Eocene extinctions should be excluded. How do we know that asteroids do not hit the Earth periodically? I asked. Maybe our failure to arrive at a theory just meant that we hadn't been clever enough. Not finding something is not the same as proving it is not there. I decided to reserve judgment....

3,274 wordsThe Case For The Existence of God by John Doe, Ph. D. Introduction Either God exists or He doesn't. There is no middle ground. Any attempt to remain neutral in relation to God's existence is automatically synonymous with unbelief. It is far from a "moot" question, for if God does exist, then nothing else really matters; if He does not exist, then nothing really matters at all. If He does exist, then there is an eternal heaven to be gained (Hebrews 11: 16) and an eternal Hell to be avoided (Revel...

Carbon Dioxide Chemical Reactions
1,434 wordsEating, or ingesting food, is one of the main characteristics of the animal kingdom. Most of these animals metabolize their food at a rapid passe. But the metabolism of a snake is much slower then many other animals. This is due to one major factor. That is the temperature in which their bodies are. The metabolism works the same as other animals. It is just slower in a snake. The metabolism needs to be slower since the snake doesn? t eat very often. This paper will prove that a snakes metabolism...

Million Years Ago Survival Of The Fittest
723 wordsLike the biblical hero Adam, a single cell let part of it's body become another being, now one of a pair. Like the heroin Eve this duplicate created more of it's species. These multiplying cells joined together into a legacy long in running. The history of our evolution is dark, we fumble for answers yet still need more light to unlock the mysteries beneath. One must remember that when speaking of the theory of evolution one is not only referring to humans but to other species of the kingdom Ani...

Million Years Ago Homo Erectus
837 wordsIn the video series In Search Of Human Origins, Don Johanson the anthropologist who discovered the oldest human fossil "Lucy" leads us from Lucy's origins as one of our earliest ancestors through the stages of evolution to the present time. Johanson considered Lucy to be "the missing link between ape and human." He discovered her in the Great Rift Valley of Africa and explains that the reason anthropologists search for clues to our origins here is because the ancient layers of the earth have bee...

Million Years Ago Long Period Of Time
1,219 wordsFrom Water to Land (Revision) Abstract: The early tetrapods were the first vertebrates to actually walk the solid earth. They began their conquest of land in the Paleozoic era around 360 million years ago. The question many paleontologists have been asking for a long period of time is whether the anatomy for locomotion on land was developed in water for swimming purposes, or if it was adapted after the creatures became terrestrial. Recent findings of fossils indicate that the transformations of ...

Million Years Ago Dry Land
722 wordsAbout four hundred and fifty million years ago, at the end of the Ordovician and in the beginning of the Silurian, the land was desolate and empty. Barren, hardly withered rock grounds, empty sand-, gravel- and clay plains, no green. Maybe some lichens. And at wet spots some algae with a couple of spider-like little creatures creeping around. In the neighbourhood of the mouth of rivers, where the water regularly flooded the land, it was probably green with algae. At such places, e. g. in Austral...

This species, which lived between three and four million years ago, is believed to be the first real hominid because it is the oldest, and most primitive of any definite hominid form thus far found. Evidence from fossilized footprints, as well as pelvic and leg bones, which were similar to modern hominids, led scientists to believe that they could walk upright. Its teeth resembled mor...

Cold Blooded Oxygenated Blood
1,437 wordsMammals have existed for the past 200 million years. According to fossil evidence, they evolved from a mammal like reptile group. These reptile ancestors were small, active carnivores. They were equipped with several specialized types of teeth. Their limbs were positioned more directly under the trunk as opposed to spreading out to the sides. Both of these characteristics are prominent features of mammals. For the past 70 million years mammals have been the dominant animals in terrestrial ecosys...
