Hunger Games Final Analysis

1. In this lab, we used different methods of picking up corks to simulate evolution and natural selection. The ones that picked up enough food got to reproduce and another person would go back in. The ones that didn't get enough food would die.
2. The pinchers were the best at picking up food, because they could grab two at once quickly.
3. The population did evolve, because the species that were better could pick two at once dominated over the slow stumpys, who died off. In the first round, there were eight stumpys. In the second round, more than half died, leaving three stumpys. In the third round, they completely died off.
4. In this lab, the placement of corks was random, because sometimes they were in a small area, and other times they were all spread out. If people didn't run for the food, they might not have gotten much, since everyone swarmed it. What wasn't random was the number of birds that started out, being about the same. This could have given birds more of a chance to pass off their alleles to make their certain type of bird.
5. If the food was smaller, the stumpys might not have even made it to the second round, the knucklers would have had a harder time getting food, and the pinchers would be about the same. If the food was larger, then the stumpys might have had a better chance, the knuckers would have would have had a harder time getting food if it was larger than their knucles, and the pinchers would have had the same amount of food. In nature, if their prey became different, they could effect how much each bird would eat.
6. Without incomplete dominance, there would only be stumpys and pinchers. Pinchers would slowely become the entire population. The stumpys wouldn't be able to reproduce, and pinchers would eat all the food.
7. Evolution is the change in allele frequency, which changes the organism's traits. Natural selection is when the organisms with bad traits are unable to reproduce, making the majority of the population have good traits. Natural selection makes evolution happen.
8. The same species tried to reproduce with the same species.This would make more of the same species, so the ones that could reproduce would grow in population.This could effect the allele frequency by making more of the similar allele from the same species.
9. In evolution, the population evolves. Evolution doesn't happen to only one organism, because evolution works over a long time, or else natural selection wouldn't work. Natural selection acts on the phenotype.
If we had more stumpys in the beginning would they survive longer?
