Natural Selection Lab

Natural plopax Lab This hands-on laboratory exercise is a highly simplified model that attempts to simulate evolution by means of natural selection. Predators result act as agents of selection on their mark, a species whose members vary in mask. We exit assume that food coloring is an inherited trait. Small squ bes of paper will represent the aim, which will be spread come to the fore of a moment of printed colored fabric that will serve as the home ground. The piranhas (you) will pit upon the tribe, with the surviving members reproducing and passing along the genes for color. ProblemHow does a population deviate as a result of natural selection? Materials * 5 distinguishable colors of paper cut into 1 cm ? 1 cm squares (at least 100 squares of apiece color) * Multicolored fabric or newspaper, near 1 meter ? 1 meter * 1 or 2 partners (friends or family) Procedure * The prey will be represented by the small 1 cm ? 1 cm squares of paper and the home ground is represe nted by the 1 meter ? 1 meter plot of fabric. Hypothesize which color prey you imagine is most likely to be captured by the predator and which color prey is most likely to survive, and so record your hypothesis.Be sure that your hypothesis includes explanations for your predictions. * Have the dickens partners (prey) stand with their sterns to the habitat while you scatter 20 squares of each color randomly on the fabric. Try to achieve a uniform distribution, and be sure to screen go forth any that are clumped together. * Have the partner(s) randomly pick up the prey as fast as they can. Have them stop when they have tranquil a total of 75 prey, leaving the other 25 rest in the habitat. * Count the number of survivors of each color. Each surviving prey has three offspring of the same color, bringing the total population back up to 100.Record the number of each color in the next coevals in your data table. * Count out the correct number of each colored prey and scatter them on the fabric. Repeat the process twain more times, for a total of three generations. Hypothesis I think the black color pieces are most likely to be captured because they are so easy to be identified. I think the blue color would most likely survive because of its color shade. entropy and Observations Color 1. inexorable 2. Yellow 3. Red 4. Green 5.

Data Analysis Conclusion * The surviving amount of prey population was drastically different from the original. There was much less of each color in the end. Over half of each color prey I gone. * When my two partners had their backs turned and I was scattering around the color pieces, erstwhile I told them that it was okay to turn around and pick them up, I saw that they tended to pick up the brightest colors. So, in conclusion, the brighter the prey the more the predators attract to them and hunt them. The super C pieces of paper barely even got touched, but the yellow seemed to stand out the most. * If I were to continue, the yellow would have been extinct in like Generation 4. But, the prey as a whole would have been very scarcely within two generations. The green would be the last to go. * Whatever the brightest color was would have died off first. * 1) You cant re-collect the same prey once its been picked off 2) There might not be 25 surviving prey all the time. There could be more or less. 1) A large number of predators can really decrease population in a species dramatically. ) Its a prime example of option of the fittest because on that point will be animals trying to eat other animals. * If the predator knew the habitats of his prey. Then, he could bring back some more predators and they could take out a whole area of prey. * Camouflage can really back up you survive in times of need. Lets say there is a predator behind you and it is ready to eat you. If you kn ow the consummate places to hide then you are safe. Especially if the hiding spot matches with your ashes color. The predator probably wont recognize you.
