Million Years Ago Homo Erectus
1,040 wordsFor years, the evolution of human beings has been researched and studied. In today's society, there are many different interpretations on creation and how humans came to be what they are today. Through much scientific evidence and studies, there is now physical proof that human beings may have evolved from ape-like creatures. Even with this, there are still disputes in the paleo anthropological field of whether or not this is true. Still, many choose to believe their religious creation stories w...

Million Years Ago 65 Million Years
2,114 wordsThe "Nemesis Theory" was an outgrowth of the discovery of Alvarez et al. , that the impact of a large (10 km diameter) comet or asteroid was responsible for the great mass extinction that took place 65 million years ago. Studies of the fossil record by Dave Raup and Jack Sepkoski shows that this was not an isolated event, but one of several mass extinctions that appear to occur on a regular 26 million year cycle. Their original paper analyzed marine fossil families, and was published in the Proc...

Million Years Ago Five Hundred
1,312 wordsOn Saturday 12 th 2000, my family and I went on a float trip on the Huzzah River in Steelville, Missouri. The Huzzah River and its surroundings were a perfect location for me to look for my fossil. Since the water level was shallow, that enabled me to look to the river bottom. Almost immediately after I began my search near the edge of the river, I spotted a rock that appeared to have some sort of shell embedded in it. I decided this would be a good specimen for me to try to examine and identify...

Million Years Ago Hot Spot
346 wordsA hot spot is said to be a volcano that is recognized by an age progression from one end of the chain to the other. An active volcano commonly serves as an "anchor" at one end of the chain. After minutes of searching the web I found a hot spot that was not included in the Hawaii or Yellow Stone hot spots. I found my hot spot near India by the island of About 66 - 68 million years ago present-day India was above the hot spot and great volumes of basaltic lava erupted to produce the Deccan Traps. ...

1,586 wordsHuman evolution is the biological and cultural development of humans. A human is any member of the species Homo sapiens, meaning wise man. Since at least the Upper Paleolithic era, some 40, 000 years ago, every human society has devised a creation myth to explain how humans came to be. Creation myths are based on cultural beliefs that have been adopted as a legitimate explanation by a society as to where we came from. The science of paleo anthropology, which also tries to create a narrative abou...

3,666 wordsIntroduction To Evolution What is Evolution? Evolution is the process by which all living things have developed from primitive organisms through changes occurring over billions of years, a process that includes all animals and plants. Exactly how evolution occurs is still a matter of debate, but there are many different theories and that it occurs is a scientific fact. Biologists agree that all living things come through a long history of changes shaped by physical and chemical processes that ar...

Big Bang Theory Million Years Ago
2,410 wordsIn my short life on this planet I have come to question things that many take upon blind faith. We all know that we must some day die; yet we continuously deny the forces at work inside ourselves, which want to search out the answers of what may or may not come after. It is far easier for humanity to accept that they will go to a safe haven and be rewarded for their lives with pleasures and fantasies of an unfathomable scale than to question the existence of a supposed omnipotent being. Yet, the...

283 wordsDuring the past billion years, the Earths climate has changed from warm, ice-free periods to cold periods where the Earth was covered with many huge glaciers, and back to warm again. We are currently near the end a warm period in between ice ages. It is believed that there were many ice ages, 36, 15, and 3 million years ago. The last ice age is estimated to have been about 20, 000 years ago. Approximately 55 million years ago the whole earth was warm. The difference in temperature of the equator...

It was dated at 4. 4 million years old. The majority of the fossils found were skull fragments. Other evidence suggests that this species was bipedal. The individuals were about four feet tall. Some fossils found indicate that radius may have been a forest dweller. The teeth resemble something between earlier apes and A. afarensis. Th...

1,623 wordsThe first question that must be posed when trying to crack the mystery of the mass extinction is to ask, throughout history were there any other occurences of this magnitude? The answer is a resounding yes. Altogether over time there has been about eight mass extinctions to large land dwelling vertebrates. The most recent was about ten thousand years ago, killing most of the giant mammals like mammoths, mastodons, super-large camels, saber-toothed tigers, and others (Bakker 428). The second ques...

For over 130 million years dinosaurs ruled the earth. Then 65 million years ago, at the end of the Cretaceous period, they died out. Nobody can really say what actually eliminated the species, although everyone has their very own idea.

Humans are said to be descendants of a single celled ancestor. Although they are different in size and shape all basic functions are alike. The more complex the organization of the cell became the more successful and developed it became. As these single celled organisms developed they became known as pre-humans. We share many characteristics with these pre-humans. Some o...
