specific environment. Contrary to the beliefs of early philosophers and scientists‚ an organism’s compatibility to its environment is caused by natural selection. Natural selection‚ the process in which individuals with certain heritable traits survive and reproduce at higher rights‚ improves an individual’s ability to adapt to their environment. Natural selection may improve an organism’s ability to survive and reproduce in its environment‚ however‚ the evolutionary process is recognizable because

TOK Essay Natural Sciences - How far do expectations influence observations? Alysia Francis In my opinion I believe that expectations influence or observations greatly. If we think something will happen we are more likely to look hard for it. If we want something to appear then it is more likely that we will think that we see it. An example of this is when people hallucinate. Someone is more likely to see a ghost if they believe or are expecting to see one. In natural sciences when looking

he consequences of natural selection for all the species that do not vary and that are genetically identical is that the environment around them may cause them to go extinct. The environment has many powerful factors that play a role in natural selection. 2. Thomas Robert inspired Darwin and Wallace to write the theory for natural selection. He was an English clergyman and economist. The essay was about the increase and decrease of resources and population. It said the while the mankind population

Natural Selection Lab 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

Biomes and Diversity Extinction is a natural selection process. Should humans strive to preserve a representative sample of all biomes or aquatic zones? Why should humans be concerned with the extinction rate? This is an interesting question. Lets consider the fact that it begins by stating extinction is a natural selection process. This seems to stifle one side of this argument.The side of the argument that rallies humans to be concerned with the extinction rate and strive to preserve a representation

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
