Benefits Of Natural Selection Essay
Natural selection would favor groups living in areas with large amount of predators. This is because when individuals live in large groups, there are more eyes to watch the predators, and therefore, more time to eat. Moreover, it favors species that usually hunt huge animals because they can catch their prey easily.
2) Optimal flock size in birds has important benefits such as a better possibility of fending off predators. When a group of several birds are watching for predators, each individual has more time to feed instead of watching. Moreover, searching for rare food, capturing prey, and finding potential mates are easier in birds with an optimal flock size. On the other hand, it also has some costs such as the increasing risk of getting

    In conclusion, the purpose of the lab Bird Adaptations was to act as a bird using different tools as a beak, and try to collect as many items as you can at each station in 15 seconds. Overall, the data collected throughout this lab supported each of my hypothesis. The data shows that certain “beaks” worked better than the other at collecting food. For example, the data shows that for the Seeds Station the tweezers worked best with an average of 9.3 pieces of food, the straw worked best for the Nectar Station with 6.1 items, tweezers worked best for the Fish Station with 8.7 items, tweezers worked best for Insect Station with an average of 8.3 items, and tweezers worked best for the Sticks Station. Based on the data, the tweezers were the most effective at collecting the most food in 15 seconds. On the other hand, certain beaks were less effective at certain stations. The worst beak for each station was;…

    Natural Selection is the environments’ favoring of a particular trait in a population. Organisms use many different methods to adapt to their environments. In this experiment one must use brine shrimp and salt water solutions to represent organisms and their environments. Some organisms like the brine shrimp adapt to changes in their environments. Brine shrimp eggs produce cysts when their environmental conditions aren’t being cooperative. Brine shrimp eggs grow hard and brown when their environment does not have enough oxygen to support them. This also happens when there is too much salt content in their environment. When the eggs become hard and brown, they can be kept for long periods of time in a dry, oxygen- free environment. When the cyst is returned to its normal environment, it continues on with its development and eventually hatches. Brine shrimp are the perfect organisms to do experiments on because they only require a short time for development. The person conducting the experiment must use 5 beakers, each with different amounts of salt in them. The point of the experiment is to see how the brine shrimp eggs respond in each dish of salt concentrate. Once the salt and water have been combined, one must place approximately twenty brine shrimp on a microscope slide. After twenty four hours, some of the brine shrimp eggs should have hatched while some have partially hatched or not hatched yet. This must be done at the twenty four hour mark and the forty eight hour mark. The data should be written down on the chart given in the experiment papers. The hatching viability must be found by adding the number of hatched eggs at twenty four hours and the hatched eggs at forty eight hours and dividing it by the initial amount of eggs placed in the petri dish.…

    Evidently, chickadees produce more intense “chick-a-dee” alarm call for smaller predators than larger predators. We could explore why natural selection favor this signaling behavior because producing longer D notes tend to caught more attention from the predators as well as increase the level of exposure under threat. In this way, we can understand how chickadees balance benefit and risk ratio between recruiting other birds for help while increasing their conspicuousness and exposure…

    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.…

    Today, natural selection is defined as the process whereby organisms better adapted to their environment tend to survive and produce more offspring. Darwin and Wallace are best known for their efforts in discovering how organism evolve and reproduce. In the late 1800s Wallace developed an understanding of how organisms are the way that they are. Following in Darwin’s footsteps, Wallace set out at sea to explore different islands. He concluded that Islands that are near each other tend to have similar but distinct animals living on them. Also, that certain organisms have specific geographic ranges but that organisms that are more similar, tend to live closer together. Throughout his travels, he found that on the Malay Archipelago Birdwing butterflies…

    What may start off having even the best of intentions could end up having some serious negative consequences. Theodore “Teddy” Roosevelt seemed to have started his belief in eugenics within a sense of nationalism where it was a woman’s duty to the state to birth and raise a family. He emphasized this view through his conservation programs where white, farming women were the epitome of the ideal type of person that should be procreating. Unlike the weak, feebleminded, retarded, deaf, blind, etc. who should not pass along their unwanted genetics. There are a few other authors in our text book, American Earth: Environmental Writing Since Thoreau, that also followed this program of eugenics masked by a conservationist agenda.…

    Living in Eastern North Carolina, I often find myself amazed at the beauty of nature. As a child, my family would travel to the local recreational center that served as a nature educational center. We would spend the day exploring the woods and appreciating nature. With my childhood being filled with the biodiversity of nature, I remain fascinated about the sounds of nature. For my Citizen Project, I decided to research animals in my community, in particular Barn Swallow birds. With this project, I will observe collective data that reported the doings and the migrational patterns of Barn Swallows. This project is quite interesting to me since I have seen these birds my entire life and one of them even nested on my front porch. With the advanced…

    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.…

    Despite the common belief that eugenics were practiced solely by Hitler and his followers during the Holocaust, the original exploration of eugenics began in the United States. Many organizations in American funded eugenic research, then the ideas were exchanged into Hitler’s possession. After Hitler set about achieving his goal of a “Master Race”, prisoners in concentration camps encountered the harsh techniques used to fulfill Hitler’s desires. In camps, such as Auschwitz, harsh Nazi soldiers would violently control prisoners. The Nazi regime wanted to eliminate the Jews primarily, along with anyone else that did not fit the Nordic race.…
