This Lab Report is an analysis of the results of a two-part experiment. In the first part, we used a gel filtration column to separate the components of a mixture composed of protein and non-protein molecules. By doing so we hoped to obtain fractions that contained single components of the mixture, while also gaining insight into the relative molecular weight of each component compared to each other. We would then plot these fractions onto nitrocellulose paper in order to determine which fractions had protein. In the second part, we would use the fractions which we had determined had protein to conduct an SDS-PAGE. By doing so we hoped to determine an estimate on the molecular weight of the proteins present in each fraction by comparing it to a tracker dye composed of a variety of molecules of differing molecular weight.

Discoveries in DNA, cell biology, evolution, biotechnology have been among the major achievements in biology over the past 200 years with accelerated discoveries and insights over the last 50 years. Consider the progress we have made in these areas of human knowledge. Present at least three of the discoveries you find to be most important and describe their significance to society, health, and the culture of modern life.

The Evolution Lab simulates environmental situations to determine effects on evolution over periods of time. This lab experiments with the evolution of finches on two different islands over 100, 200, and 300 years. By manipulating parameters that influence natural selection, the effects that natural selection have on the evolution process can be studied.

This book has been molded to be a breakdown of how various fields in science have progressed over centuries as mankind has advanced. The book starts off introducing the idea that the telling of natural history has changed numerous times as humans have evolved. We also learn to agree that our knowledge has been shaped by the tools available and the perceptions of its users. In the earliest stages of life, Muehlbauer states “…observers of the natural world had only their senses to work with, and were limited to visual, auditory, tactile, and olfactory descriptions perceived by the unaided

1. Did the construction of the phylogenetic tree based on the 14 living Caminalcules change the way you would group Caminalcules species in your taxonomic classification (chart)? What does this suggest about classification based on strictly of similarity versus evolutionary relationship?

Creationism, it is theory that claims every element in the earth, including living species, are all created by the god as the Bible said, which denies the evolutional theory came up by Charles Darwin. Then, since Darwin’s evolutionary theory is testable and make solid predictions whereas creationism cannot be tested nor predict precisely, it has been considered as a pseudoscience. However, recently there is a Ph.D. Biochemist bring creationism theory back to the audience again, his name is Duane Tolbert Gish from University of California. Dr. Duane T. Gish has written several books and articles to support creationism, and the most famous one is Evolution: The Fossil Say No!, which published in 1978. In his article, he denied the evolutionism since he claims there is insufficient fossil evidence to support Darwin’s theory, and which would prove creationism is real.

Define evolution? A slow change of something into better form. The word evolution means change, and the process of evolution reflects this definition as it applies to populations of organisms. Biological populations are groups of individuals of the same species that are sub-divided from other populations by geography and are somewhat independent of other groups. Biological evolution, then, is a change in the characteristics of a biological population that occurs over the course of generations. The changes in populations that are considered evolutionary are those that are inherited via genes. Changes that may take place in populations due only to short-term changes in their environment are not

The late Stephen Jay Gould, a noted paleontologist who once described himself as an “agnostic leaning towards atheism,” wrote the classic treatise Evolution as Fact and Theory for Discover magazine back in 1981. His distinguished career and scientific achievements did earn him respect amongst his peers, but to the general public he is best known for his popular science writings and, to smaller circles, as a champion of evolution. As his treatise was written for a non-academic, science themed magazine, a basic understanding of science, and specifically evolutionary mechanics, was assumed of his audience. The treatise itself is on the often overlapping distinction between “theory” and “fact”; two words, he asserts, that creationists

The ongoing scientific investigation of how exactly evolution occurred and continues to occur has been an argumentative idea amongst society since Darwin first articulated it over a century ago. The scientific basis of evolution accounts for happenings that are also essential concerns of religion; both religion and science focus on the origins of humans and of biological diversity. For instance, in the reading “Truth Cannot Contradict Truth,” Pope John Paul II, addressing the Pontifical Academy of Science, discussed the matter of God as creator of man. The Pope explains that men cannot relate to animals because men are superior. The reasoning for that is because God created humans under his likeness. What the church is saying about mankind

The foundation for the theory of evolution was laid by Charles Darwin (Rose, n.d.). He developed hypotheses about natural selection which helped scientists develop the theory. Evolution is a theory and not a hypothesis because evolution has been proven by vast amounts of scientific data, research, and testing. The definition of a hypothesis is an educated explanation that needs to be researched and tested but has not yet been proven (Earman, 1984). There has been no scientific evidence to disprove the theory of evolution.

Biologists use the ideas of cell theory, hereditary and genetics, and evolution through natural selection in many different ways. While being very different areas of study, they all share a core idea. This idea is that cells duplicate, and sometimes experience random mutations. From this very basic idea, scientists can theorize that all life on earth came from one or a few very simple cells, and are related through this. But the diversity of life today also shows how these related cell groups evolved and changed.

Charles Darwin's theory of evolution centres on the idea that species compete to survive, and favorable characteristics are passed on from one generation to the next. Darwin said that evolution took place by a process of natural selection or survival of the fittest. This meant that the animals and plants best suited to their surroundings survived and were able to pass on their genes to their offspring. The ones that weren't best suited died off and didn't get the chance to reproduce.

The definition of Evolution is ¨the process by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the earth,¨ (Dictionary.com, 2018). Although, the actual definition is hard to comprehend. Some consider Evolution to be a somewhat ridiculous topic that is far from true. Though others believe that, ¨Evolution by natural selection is one of the best substantiated theories in the history of science, supported by evidence from a wide variety of scientific disciplines, including paleontology, geology, genetics and developmental biology,¨ (Than, 2018). The main idea of Biological Evolution is that all life on Earth share a common ancestor. The term is a way of understanding life.
