DNA, shorthanded for Deoxyribonucleic acid is a nucleic acid contains instructions for the development, functionality, and maintenance of new cells. DNA consists as chains of nucleotides, in two antiparallel strands in a double helix, connected by hydrogen bonds between complementary nitrogenous bases. Segments of DNA carrying genetic information are called genes, which mostly code for a specific type of protein. This lab will focus on the gene pGLO.…

* natural selection-The process by which individuals that are better adapted to their environment are more likely to survive and reproduce than other members of the same species.…
Natural selection is the driving force in evolution because it is what trait offspring. There are many cases of evidence showing this such as the peppered moth population, the blue mussels, and the finches that we studied.…
Genes are segments of DNA that code for proteins or RNA molecules. These genes are the genetic material that is passed down from generation to generation in all species. The individual DNA segments each individual carries are known as their alleles or genotype. When two alleles are identical they are homozygous and when they are different they are heterozygous. These alleles are expressed physically through what is known as the phenotype. An example of a phenotype of a gene is hair color, which may be blond or brown.…
Natural selection is the process by which organisms with variations most suited to their local environment survive and leave more offspring. Natural selection “drives” evolution.…

Before Darwin, people believed that species were unconnected, unrelated and unchanged since the moment of their creation. They also believed that people were not part of the natural world and were superior to every other species. Darwin’s theory challenged these traditional views. Many people either still believed in the 6 day creation theory, or thought that the idea of apes being our ancestors hard to believe, and preferred ancient stories of creation.…
Charles Darwin in 1859 published On the Origin of Species, he explained his theory of evolution. He presented evidence that would further explained his reasoning. The first Darwin looked at the fossils and looked at the geological layers. Next compared the structural of the human hand, bird wing, and a cat paw and hinted that we come from common ancestors. His finally observation was the dramatic change in domestic plants and animals by selective breeding. Darwin believed that species started to change their structure, psychology, and behavior that would help with…
Evolution is basically the change in the heritable characteristic or traits in living organisms which are passed from one generation to another and gives rise to diversity at every stage of the organism’s biological organisation. The process of evolution was not well understood until 19th century when Charles Darwin proposed the scientific theory of natural selection as a driving tool in evolution. The process involved both the macroevolution in which organisms went through major evolutionary changes over a long period of time and acquired different traits from different parents or ancestries and the microevolution in which a group of organisms went through minimal changes with time but the traits they acquired were typically from the same ancestor.…
For such a complex concept a direct definition leaves more questions than answers. When a species changes biologically over time, evolution guides the process. All living species on earth effect one and other, during the evolutionary process. We depend on that change for our change and they depend on us to affect their change (Park, 2014). The success of those changes depends on the ever constant fight to adapt to the natural environment. For a species to survive depends on the best genetic mutation to survive the current environment. Humans use natural selection or changing the environment of species to cause the desired mutation to help produce food.…
The tree of cousinship refers to the similarities shared between the skeleton of multiple different species such as the mammals. Although the different skeletons contain similarities in structure and placement of certain bones, it is as though they have been taken apart and molded in different places to produce new versions (Dawkins 2009). This creation of seemingly new versions of the same skeleton is evidence of a common ancestor shared between species and the differentiation of traits along descendant lineages (Dawkins 2009). This example of evolution works against the creationist argument because it begs the question of why a divine creator would choose to create many different versions of the same species in the first place. In conclusion,…
