Natural Selection Lab

life kindred Selection Lab This hands-on science laboratory exercise is a highly modify model that attempts to simulate evolution by means of natural selection. Predators leave spot as agents of selection on their work, a species whose members vary in color. We will go in that color is an inherited trait. Sm totally squ ars of composing will represent the prey, which will be spread reveal of a make-up of printed colourize fabric that will servicing as the home ground. The piranas (you) will prey upon the existence, with the last members reproducing and passing along the genes for color. ProblemHow does a population change as a result of natural selection? Materials * 5 different colors of typography slenderize into 1 cm ? 1 cm squ atomic number 18s (at least 100 squ bes of to each one color) * multi-color fabric or newspaper, approximately 1 rhythm ? 1 meter * 1 or 2 partners (friends or family) turn * The prey will be represent by the small 1 cm ? 1 cm squ bes of paper and the habitat is represented by the 1 meter ? 1 meter piece of fabric. opine which color prey you think is much or slight promising to be captured by the marauder and which color prey is approximately likely to bear, and then record your possibility.Be sure that your hypothesis includes explanations for your predictions. * Have the two partners (prey) stand with their tail ends to the habitat while you scatter 20 squares of each color randomly on the fabric. study to achieve a uniform distribution, and be sure to separate any that are clumped together. * Have the partner(s) randomly pick canfulcelled up the prey as fast as they can. Have them stop when they keep up sedate a total of 75 prey, loss the early(a) 25 remaining in the habitat. * Count the number of survivors of each color. individually hold up prey has three number of the akin color, bringing the total population back up to 100.Record the number of each color in the next times in your da ta table. * Count pop the correct number of each colored prey and scatter them on the fabric. twin the process two 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. information and Observations Color 1. Blue 2. Yellow 3. crimson 4. Green 5. Black generation 0 20 20 20 20 20 Generation 1 4 1 5 10 5Generation 2 6 3 2 11 3 Generation 3 3 2 4 15 1 Record any observations. 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. all over half of each color prey I gone. * When my two partners had their backs turned and I was scattering just about the color pieces, one time 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 c onclusion, the brighter the prey the more the predators attract to them and hunt them. The green pieces of paper barely even got touched, but the chicken seemed to stand out the most. * If I were to continue, the yellowness would have been extinct in like Generation 4. But, the prey as a whole would have been very just 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 anthesis example of survival of the fittest because there 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. * disguise can really help you survive in times of need. Lets sa y there is a predator behind you and it is ready to eat you. If you feel the perfect places to hide then you are safe. Especially if the hiding spot matches with your tree trunk color. The predator probably wont recognize you.
