What discoveries or practices helped to make it believable? During Darwin's time, a few factors made natural selection difficult to accept. Religion, especially the Christian Bible, played a role in this, as it taught that the earth was only 5000 to 10,000 years old. Additionally, the physical sciences of the time appeared to support this religious viewpoint. Many people believed in another factor that clashed with Darwin's theory during his time; that the sun burned fuel like a stove or campfire. If this was correct, the sun's age would likely to be 10,000 years or less, which would be in correspondence with the biblical view. The practice that helped make it believable was during Darwin's time in which people were very familiar with animal breeding so most people had at least some experience with farming and agriculture, so they could envision plants and animals changing over decades, thus making natural selection something they could believe in. 3.How did the industrial revolution influence the color of trees in England? What is “industrial melanism”? The color of the trees turned darker throughout the Industrial Revolution due to the use of machinery that released soot, smoke, and other dark gases which impacted the environment surrounding the area. As a result of the industrial revolution, dark pigmentation, or melanism emerged, leading to the emergence of industrial melanism. These changes would show how environmental changes that would be affected by industrial melanism would then in turn affect the evolution of species by creating a darker colored habitat which animals would adapt to through their genetics. 4.Based on your observations in the web-based simulation tool, how did the color of the moth influence a moth’s chances of survival? Was this effect strong or weak? The color of the moth was what determined the moths being able to blend in their environment, which was what directly influenced chances of survival. Directly influenced. For example, in the lighter colored tree, the results of the lighter moths being more in numbers in comparison to the dark colored moths, depict a strong effect. We got this information based on the data chart from our simulation. For example, in our simulation, in most of the results, the percentage of the light-colored moths outliving the dark colored moths was consistently higher as shown in run 4 where the presence of the light-colored moths reached 92% and the dark colored moths reached 8%. The reason why we have a higher percentage for light-colored moths is due to their ability to be camouflaged due to its colors. 5. How did you see natural selection in action during these simulations? During the simulation, natural selection was observed in action using different attacks. As the predator (the bird) pursued the moths, it showed a preference for a certain type over another based on the color of the moth's wings. Over time, this selective pressure caused a shift in population composition, favoring a type that was less visible to the predator. The situation shows how predation can drive changes in evolution within a population by favoring individuals with traits that improve their chances of survival and reproduction. 1 A Mobile View Read Aloud Headings
