1. We simulated evolution by having different variations compete for food. The more food someone got, the more offspring they could have. As the trials progressed, the population began to be almost entirely pinchers.
2. The pincher phenotype was the best because it was the easiest to collect food with. As a result, pinchers could collect more food and have more offspring.
3. Yes, the population was 97% pincher at one point, escalating from 52% just two trials before.
4. The placement of the food was random, giving some people advantages in collecting food. If the food was placed next to someone, they could collect more. That people would have more offspring.
5. If the food was too big for pinchers and knucklers to grab, then stumpys would be the best phenotype. If the food was too small for stumpys to grab, they would have been even less successful.
6. Yes, stumpys would have gone extinct.
7. Natural selection influences how species evolve. Natural selection picks which traits are the most favorable, and evolution is the process of how that species changes.
8. Individuals used their hands instead of just their fingers or knuckles. This made it easier to collect food. It would make that allele more frequent in the coming populations. In nature, organisms will do whatever they can to get a leg up, as was shown in our experiment.
9. Species evolve in evolution. Phenotypes and genotypes evolve because organisms may choose their mate on what makes their offspring survive best or what mate they like the most. One will change the phenotype while the other will change the genotype.
10. How does humans affect natural selection for all species? Do humans' phenotypes or genotypes evolve more?
