Fossils are a large part of discovering about the past, but to understand how fossils change over time, genes also need to be investigated. These investigations are just as important as the fossils, because of how DNA can be tested through the use of embryos. During Shubin’s expeditions into the Artic, one researcher, Randy Dahn, was experimenting with the embryos of sharks and skates. He would use various chemicals on the embryos, and examine the results to see what changes that the chemicals…

41. What is the Innermost Essence of ‘MATERIALIZATION’ & ‘DEMATERIALIZATION’? • An average Terrestrial Man was puzzling and at the same time fascinated by phenomena of Materialization or Manifestation which is Appearance or Creation of (Living) Matter from an unknown source, and even more with ‘Teleportation’. The last is Dematerialization and Re-materialization which is a ‘transfer’ of Matter or Living Body from ‘point A’ to ‘point B’ without traversing Physical space between them. Per example…

Forces of Evolution Mammals have evolved in ways that are beneficial for them, ensuring their survival and turning them into the beings that we are familiar with today. Species, organisms which have always had features in common, evolve through four main forces: gene flow, genetic drift, mutations, and natural selection. Genetic drift involves a population, a group of the same species that lives in the same geographical and temporal location. Genetic drift causes changes to occur in members…

proved the theory of uniformitarianism (6). The theories suggest that earth has evolved from what it used to be centuries ago, and can be concluded that these are the external factors that have contributed to the environmental changes that affect organisms, and at last forcing them to evolve (3,4,6). These theories relate to evolution because geological factors such as barriers affect reproduction, as well as, cause catastrophic changes in the environment affecting natural selection (2,3,6,7).…

Nitrogen cycling is a vital factor in how plants and organisms survive in ecosystems. Different genes in bacteria DNA allows for NO₃, in plants, to be converted to N₂ without releasing N₂O into the atmosphere. With a better understanding of which gene can convert N₂O to N₂, people can have a better understanding of what factors affect the nitrogen cycle. The genes that are responsible for converting NO₃ to N₂ are nirk, cnor, qnor, and nosz. Nosz is responsible for coding enzymes to convert N₂O…

In Neil Shubins’ “Your Inner Fish: A Journey Into the 3.5-Billion-Year History of the Human Body”, he takes the audience on the journey of the discovery and history of how different organisms and adaptations have converged to form a relationship between fish and tetrapods. Shubins first relates the evolutionary fact that humans and other forms of “tetrapods’ major body systems have developed from fish and sharks” (20), through his time on the field as a paleontologist. He describes his multiple…

Evolution is the theory of modern biology, concerning all biological areas, this theory has supported evidence and many scientists believe it to be truth. Creationist beliefs are not a scientific alternate interpretation to evolution. This is the reason why creationism should not become part of public school curriculums, first for the fact that it is illegal, the First Amendment to the U.S. Constitution prohibits the government from establishing religion. Requiring that public schools are not to…

Catholic College biology class, took on the role of a field officer for the Department of Environment and Climate Change to investigate the biological community present near Euroley Bridge, Yanco. During their time, they were to observe the various organisms that are found in the ecosystem, taking into account their surroundings amid this process. They were provided with a booklet that had various activities which were intrinsic to their Field reports such as a site plan and a profile-transect.…

out what is wrong with the animals brought to their clinic, Dr. Hooker suggests, “Experimenting on animals is just a part of life. Of course some vaccines will not work. The world is not perfect and neither are the people living in it.” Some living organism has to be the first one to try a product for the first time. Biochemists will continue to experiment to find new medicines in order to come up with a solution to cure animals and humans with…

During the Medieval ages in the city of Florence, Italy there were three main social groups that lived, the ones who pray, fight, and work. A wall surrounded the whole city, there were still some buildings outside of the wall. The wall protected the people of Florence from any danger and from the outsiders. There were principle buildings where each of those three social groups lived in. At the top of the medieval society were the first estate, the ones who prayed (clergy) lived in churches,…
