Dern Mosaic: Humanities Seminar 852 January 30‚ 2015 Gradualism—the Principle Flows Through the River of Time Although the Darwinian evolution theory came out 150 years ago when it was first introduced in On the Origin of Species in 1859‚ nowadays there are still many people who firmly believe in the creationism‚ even some who are well educated. In chapter three of River Out of Eden Richard Dawkins brings out this situation and refutes creationism by citing scientific experiments

Assignment: SCIE211 Phase 2 Lab Report Title: Speciation Instructions: You will need to write a 1-page lab report using the scientific method to answer the following question: • What would happen if a species within a population were suddenly split into 2 groups by an earthquake that creates a physical barrier like a canyon? When your lab report is complete‚ post it in Submitted Assignment files. Part I: Use the animated time progression of speciation to help you write up your lab report. Part

Fossil record and genetic record of relationship between the species The oldest fossil evidence found was approximately 3.8 million years old. Although these were said to be the “oldest” there have been more modern research done that shows DNA comparisons of ancient fossils and more recent bones. This evidence is known as the clue to the ancestor of all cats including the domestic cat‚ margay‚ and marbled cat. In China‚ Archaeologists have found the first clear evidence of domestic and/or

Evolution and Classification Test Darwin/Lamarck Darwin’s observations: Usually the numbers of offspring produced are far greater than the ones that survive Natural resources are limited. This leads to a struggle for existence with only a fraction of offspring surviving to the next generation Slight variations (mutations) occur by chance within a population These variations are inheritable Darwin concluded that living organisms were evolving through

In this context we may ask: What are living things? We humans‚ ourselves are living things. How do living things differ from non-living things? To answer these questions‚ we must first define the word life

the world‚ why should we worry about it? Speciation results in new species filling the ecological niche of extinct species. Why should we care if we speed up this process? Biologists say there are four main reasons to care about extinctions. First‚ the world’s species are a vital part of the earth’s life support system. A second reason is that species usually contribute to economic services. The third reason is that it takes 25-50 times longer for speciation to occur than extinction. Finally‚ we have

Early human evolution is characterised by speciation. The term speciation refers to “the formation of new and distinct species in the course of evolution”. Recently‚ experts in the field of evolution have given special emphasis to the new and most controversial issue of Homo floresiensis. Homo floresiensis (known as the Hobbit Man and LB1) is the little bodied and an extinct species that was discovered from a fossil and simple stone tools in 2003 on the island of Flores in Indonesia. Scientists indicate

Introduction The continent of South America has about one-eighth of the Earth’s land surface‚ situated between latitudes 12°N-55°S and longitudes 80°-35°W; no other continent has a greater latitudinal span. Eighty percent of its land mass is within the tropical zone‚ yet it extends into the subantarctic. The extensive zones of temperate and cold climates in the vicinity of the Equator‚ in the Andes‚ are unique. The land area of about 17‚519‚900-17‚529‚250 km² is under the jurisdiction of 13 countries

Congo River was formed in what is now the Democratic Republic of the Congo. (San Diego Zoo 2) The river geographically segregated groups and individual chimpanzees south of the river resulting in these chimps being reproductively isolated. Allopatric speciation took place as a response to new selective pressures and from this separated population a new species evolved‚ the bonobo. (Jurmain 121) Today the Congo River is the bonobo’s northern and western boundary with the Lomani River its eastern limit
