Evolution and Religious Creation Myths How Scientists Respond by Paul F Lurquin and Linda Stone. Oxford University Press, 2007 xi + 201 pages. $24.99 Electronic. Evolution and Religious Creation Myths How Scientists Respond is a book published by the Oxford University Press, about the different theories behind creationism and how we got here today. It breaks down different aspects of creation and evolution. Creation is a subject that people have speculated over for many years. It has been…

Atheist or To Have Faith We have always wondered about how everything in this universe was created or how we humans came to be. We humans have come up with explanations to these answers, but each explanation differs from one to another. These explanations are called religions. Each religion has its own story and creator/creators. These religions only contain stories on what happened but there is little to no actual facts if what these religions tell us is true or not. So because of this, many…

causing cancer is about 0.004 percent. In 1.28 billion years, 89 percent of the time, half of the potassium 40 decays to calcium-40 by emitting a beta particle, while 11% of the time it decays to the gas, Argon-40, by electron capture. Besides radiometric dating, there are no specific commercial or medical uses associated with the radioactive properties of potassium-40. Accordingly, radiologists use potassium-40 to determine the age of objects, the older the rock, the more argon-40, while the…

Jesus E Fernandez WCIV 10100-H Dr. LePree Fall 2016 Lucy; the most important discovery of the 20th Century Ever since discussions of human ancestry began, many people believed that Europe was the home of the first ancestors of humankind up until the end of the 20th century. An American paleoanthropologist by the name of Dr. Donald Carl Johanson, visited Ethiopia as part of the International Afar Research Expedition in 1973, as a result of this expedition, Dr. Johanson found a knee of a…

In preparation for this assignment I talked with several people, asking them the interview questions, I will address the answers of four of the people I talked with. Each question is listed below with a summary of the answers following. How long are the days in Genesis 1? Why? Three of the four persons basically said the exact time is unknown. The fourth said a day was from sun up to sun down no hours were specified. How old is the Earth and life? Why? One person said about 6,000 years, two…

An isotope is an atom containing different numbers of neutrons, differing in atomic mass. Basically an atom with a different atomic mass. What’s special about radioactive isotopes is that a radioactive isotope has a nucleus that decays spontaneously giving off particles and energy. 6. Radioactive tracers are used in science to label certain chemical substances, so metabolic processes can be followed and substances can be located in an organism. Radioactive tracers are important diagnostic…

The article I found is on the discovery of Homo naledi. Happened upon only by chance, the struggle to find Homo naledi was as hard as placing it with either Australopithecus or Homo. I found this article interesting because the discovery of a potentially new species could give us a clearer picture of our ancestors. We may never know the complete story, but as long as we keep on researching and exploring new ideas, our understanding will grow. In addition to adding to our understanding of…

provide photographs of the past, bones, teeth, shells and imprints of animals and plants. Fossils provide answers to the changes of species and plants and what life was like more than four billion years ago. By using methods like relative and radiometric dating the can find out the age of the fossil, which helps fill the gaps to the knowledge of how species changed over time. DNA, which is also called Deoxyribonucleic Acid, is very helpful for evolutionist because DNA is the blueprint for all…

Who or what is responsible for the occurrence of life on earth, and possibly many other planets, is a question that has plagued humanity for thousands of years. Once life was present on the planet, scientists largely agree that natural selection, the theory presented by Charles Darwin, took place allowing the hundreds of various species to emerge from one common ancestor known as the last universal common ancestor (LUCA) (Christian, Brown & Benjamin 2013, p. 57). Theories of how life actually…
