From my Blast results the most similar gene sequence to the gene of interest was taeniopugia guttata that had a max score of 2313 and an Ident % of 100. As well as it had an e-value of 0, which means that it’s closely related to the gene of interest. This species is located on the birds’ branch on the cladogram because it has features of a bird. From my data collected of Gene sequence the second most related gene sequence was from meleagris gallopavo . It had amax score of 1781 and an 92% Ident and an e-value of 0.…

3. Based on the results for beak size and population numbers, what can you conclude about evolution when all factors are equal?…

This hands-on laboratory exercise is a highly simplified model that attempts to simulate evolution by means of natural selection. Predators will act as agents of selection on their prey, a species whose members vary in color. We will assume that color is an inherited trait. Small squares of paper will represent the prey, which will be spread out of a piece of printed colored fabric that will serve as the habitat. The predators (you) will prey upon the population, with the surviving members reproducing and passing along the genes for color.…
Introduction- Throughout the history of man kind one question has been constantly ASKED and never seems to get a definite answer. The question is who are we? And where do we come from? Rather then spark a religious verse science debate and draw a very emotional line in society we let everyone believe what they want to believe. However regardless of what you want to believe facts are facts and science is science. After going through the Diversity one, two and three labs many things became evident that were somewhat unclear before. One of these things is that we , as man may argue about where we came form and when we got here but we are mere children in the history of planet earth and mere infants in the life that has existed here. The goal of this lab was to understand and be familiar with the millions of organisims that live on earth everday and hiow they got here. The goal was to understand how certain species died out, how they evolved to survive and how organisims have managed to make it millions of years on this planet. This lab takes a look at the three domains Bacteria, Archea, and Eukarya, which contain animals, protists, fungi, bacteria, and plants. And after our observations from the lab me and mark grey my partner concluded many concrete facts about life, evolution, traits and survival.…
My hypothesis for this experiment was that if there are more children per generation, then it will increase the rate of evolution. I believed this to be the case because there is more opportunity for mutation and for diversification in offspring, if there is more offspring. This could be easily backed up with a basic knowledge of statistics. The second experiment, was a basic comparison to the first test. It was to see if the fertility rate and a simplified gene code would get a different result. For this experiment, my hypothesis was that if the adaptation is more simplistic, then it will increase to rate of evolution. I believed this to be true because with a less complex adaptation, there is more chance that it will reach the genetic code needed. We discussed this idea in class. This can be backed up by an analogy that Dawkins made. This analogy is that it would be almost impossible for airplane parts that were sitting in a junk yard to be blown up by the wind and be put together to create an actual airplane (Dawkins, 1996). Why is this? This is mostly because it is an incredibly complex structure. As stated by Dawkins it would take probably the entire existence of the Earth for the probability of that event to…
To begin this experiment, go to the Evolution Lab located with the University of Phoenix student website. Once at the lab’s page, click Start Lab. This will take you to an applet to view and change the inputs for variables. For this experiment, the variable inputs on Darwin Island will be changed and Wallace’s inputs will remain as a constant variable. The only variable that will be the same for both islands is the heritability. The following table shows what the final numbers for each variable are. After changing Darwin Islands’ inputs, you may now run the experiment. Darwin’s Island sized was changed to 1.0 km, double what Wallace Island is. Some consistency was wanted, so inheritability remained at 1.00 and Darwin’s variance of beak size went up to 1.00 instead of Wallace’s 0.7. The initial beak sized was increased by one inch on Darwin’s Island. Birds with the best-suited bodies and beaks for the particular environment survive and pass along the…
After offering these experiments, Dawkins summarized that:“The reason eyes and wasp-pollinated orchids impress us so is that they are improbable by luck are odds too great to be borne in the real world. Gradual evolution by small steps, each step being lucky but not too lucky, is the solution to the riddle” (Dawkins 83-84). This summery reflects the relationship between the experiments and gradualism where profound change is the cumulative product of slow but continuous…

Darwin’s theory of natural selection is not supported by the geological or fossil record, since there have been little to no remains of intermediate species found in fossils. Darwin explains this by using the imperfection of the geological record, as changes in land over time means that species will often not be preserved in a way that can be studied by scientists. He also references Charles Lyell’s Principles of Geology, which states that the earth’s surface is constantly changing, as evidenced by the degradation and deposition of landmasses. These changes happen slowly, over hundreds of millions of years, implying that life has been present of a long time, and the number of fossils found is a miniscule amount compared to all the living things…
Charles Darwin after studying the beaks, concluded that each shape seemed to serve a purpose suited to the particular island (Lee 15). He concluded that finches who had short, fat beaks mostly ate nuts and on islands where the main food source is insects the finches had long, skinny beaks (Lee 15). Based on this evidence Darwin developed a theory that at some point in the past, one type of finch arrived at the islands and then evolved differently on each island (Lee 15). This theory is called natural selection, which ensures that traits that promote survival will win the struggle for existence (Akert, Aronson, Sommers, and Wilson 43). This theory also states that any trait that lowers our chances of survival, such as those that cause life- threatening diseases, reduce the chances that we will produce offspring and pass traits to other generations (Akert, Aronson, Sommers, and Wilson 316). However, if traits are not passed on to different generations, there would be no mechanism through which traits could reappear in subsequent generations and therefore there will be no way for a species to…
