Madeline - Slide 1 and 2: Today we will be talking about evidence of evolution from molecular biology and biochemistry, the main topics covered today will be molecular biology and biochemistry, DNA comparison with chimpanzees and other species, serological tests, and cytochrome C.

Jillian - Slide 3: The structure and function of cellular components can be used as evidence for evolution. The two fields that contribute to molecular evolution research are molecular biology and biochemistry. Molecular biology is the study of cellular components such as proteins, carbohydrates, nucleic acids, and lipids. Biochemistry is the study of the chemical processes in organisms. These two fields of science act as evidence because they show that organisms

The combination of these two components results in the formation of a precipitate. The characteristics of the precipitate show the relationship between the organism that gave the blood serum and the organism that was injected with the blood serum. A precipitate with diluted antigens means that the two organisms have a strong genetic relationship. A precipitate with less diluted antigens means that the two organisms have a weak genetic relationship. Overall, the greater the reaction in the test tube, the stronger the genetic relationship.

Slide 17: Here is an example of a serological test with humans and chimpanzees. The human blood serum is injected into the chimpanzee. The serum acts as the antigen which causes the chimpanzee to produce antibodies. The two components combine so that the antibodies can fight off the antigens. This forms a precipitate which will have diluted antigens therefore humans and chimpanzees have a strong genetic relationship.
Slide 18 and 19:Cytochrome C acts as another form of molecular evidence for evolution. Cytochrome C is a protein located in the mitochondria that helps transport electrons during cellular respiration. Cytochrome C is also released during apoptosis which is controlled cell death. The cytochrome c protein is essential to life so it 's present in all living

The remaining 93 amino acids in the protein sequence can differ in organisms because of random mutations that have occurred over generations. Genetic relationships between organisms can be determined by comparing their sequences of the 93 remaining amino acids. Two sequences that have little to no amino acid differences means that the two organisms have a strong genetic relationship. Two sequences that have many amino acid differences means that the two organisms have a weak genetic

    Fossil record can be described as the collection of the remains of past life. Furthermore, theoretical evolution is considered theoretical because the process of natural selection in times before the development of science can never be fully or concretely proven; only theorized. Taxonomy would be explained as the branch of science regarding the classification of organisms. Paleontology is considered to be the greatest source of empirical knowledge in terms of understanding the history of life.…

    Evolution There have been many arguments on the topic evolution. In the Qualia Soup video: Evolution, the topic will be broken down and the truth will finally be revealed. The scientific theory of evolution explains how living organism develop and diversity over generations. It not explains the origins and development of the universe as in cosmogenesis. It also does not explain how life first began such as abiogenesis.…

    Introduction: Evolution the change over a period of time is important because it demonstrates scientist the need of our ancestors for a certain body part that humans do not need which are called vestigial structure. One of the main evidence regarding evolution is fossils. Fossils are mostly used to determine structure similar animals have that humans have in order to draw conclusions. Another evidence is blood which generally shows similarity in the dna of two different mammals. The purpose of the lab is to examine skulls and see how they relate to each other and find similarities between each other.…

It was in 1856 that the first bones of an ancestor of the missing man ... were encountered Neanderthals. "The television program, however, contradicting website States that Neanderthals not only have a brain larger than most human beings and had a greater sense of smell, they were around during the time of modern man, and therefore were not our ancestors. They are not a "real missing link" of a "forerunner of the missing man." For a clear refutation of Neanderthals as being something of a brute ancestor of ours, which is still paraded in the media and in school textbooks as evidence of the evolution of molecules to man.…

    The aim of the data analysis exercise was to determine genetic relationships between the HSP70 amino acid chains of fourteen different organisms. The data produced was an identification table, a sequence alignment diagram and a cladogram. In cladograms the branches are not representative of the evolutionary time that has occurred. Heat shock proteins (HSPs) are in a class of proteins called molecular chaperones. (Kiang, J.; G, Tsokos. 1998).…

    Yes, atavism and fossils do suggest theories of evolution and how we have come from one organism however they are subjective and have many faults. DNA is accurate and scientifically proven and testable. It proves that all organisms share a common structure meaning we come from a common ancestor as well as giving more thorough understanding of organisms evolved from one organism while branching off other pieces of evidence like vestigial organs. They all however show that evolution is a good scientific theory as each explores how we come from similar organisms and can help explain evolutionary…

    Scientists classify organisms by grouping and sorting organisms together based on their physical structure, evolutionary relationships, embryonic similarities, genetic similarities, and their biochemical similarities. The most popular form of classification system used by scientists is Linnaeus’s System of Classification, by which organisms are classified and grouped into 6 different kingdoms; bacteria, archaea, protista, fungi, plant and animal. By classifying organisms it provides scientists with an easy way to study organisms efficiently, and allows for predictions and knowledged observations. Knowledge about classification allows scientists to make predictions about organisms, living and extinct. It allows for a comparison and understanding…
