These circumstances resulted in the preferred traits being the most adaptable and able to reproduce, therefore assign the traits down to the next generation. To get a closer look at natural selection, we set up simulations to look at the reproductive success of an individual relatives to others, or biological fitness. The hypothesis we concluded for the simulations is that the predators on the light towel bench, which represents one of our three environments, would be more fit than the predator in the other two environments.
METHODS To test this, we divided into three different groups to put in an environment as the population as predators. We used a fork, a spoon, chopsticks, and a forceps o as our utensils to acquire the prey, The prey population is represented with beans that differed in size, shape and color. For our experiment, we used lima beans, lentils, and black beans. We then scattered the beans, or the prey, through each environment for equal opportunity. At the start of the experiment, we counted ICC of each bean so that each trait (bean types) is included in a balanced portion of the population.
For three rounds, we timed ourselves for one minute and attempted to catch as much “prey” as we could With our utensil. The umber of prey we caught determined a predators fitness. The fitness of the first generation Will then determine the makeup Of the next generation. We used a table to compare the predator and prey in each environment for three generations. We timed ourselves for one minute to capture as much prey, or beans, as possible. In addition, they were certain restrictions applied to the simulation.
Firstly, we were only allowed to use our own utensil to capture the prey. Also, each predator (group member) was given a cup to gather the prey and was to be kept on the table. And lastly, we could only capture one prey at a time and must be placed in the cup correctly, If a prey item is dropped, it was considered as an unsuccessful capture RESULTS In the first round, there were a total of 7 offspring, with the spoon utensil having the highest percentage in Generation 1.
The lentils and lima beans bean decreased in its number of offspring. In the second round, the spoons doubled offspring and consequently were still the leading predator in Generation 2. This time only the lima beans decreased in offspring count The third round resulted n an offspring of 12 predators, with the spoon having now almost 60% of the population. The lima beans unfortunately died out and produced no more offspring.
