Model the process of Natural Selection
Aim: To demonstrate the process of Natural Selection through the selection of organisms by colour.
Hypothesis: If yellow and green toothpicks are used, the native birds will be attracted to the yellow toothpicks.
Materials:
• Yellow & green toothpicks
• String
• Stopwatch
• Measuring device
Procedure:
1. Gather required equipment.
2. Using the measuring device, measure out a 8 × 8m square.
3. Using the yellow and green toothpicks (worms), scatter them randomly over the designated area.
4. Allow students (native birds) to enter the area to prey on the toothpicks (worms) in the designated time allowed.
5. Allow the farmer to enter to send the native birds away.

    SCI203 Phase 2 Lab Essay

    The purpose of this experiment is to determine the outcome of a barrier divide between two species. • Introduction o Natural selection is the evolutionary change due to variation in production of species with different variable characters. (Montgomery, n.d.) Such an example occurs when birds prefer red bugs due to possible taste or color than their counter species- green bugs. This in return will affect the higher reproduction of green bugs thus making red bugs become nonexistent.…

    Bio 14 Lab Essay

    The basic set-up for this experimental design would consist of eight plates, each with a single female beetle and eight beans. The two independent variables would be whether the female of South Indian descent or Burkina Faso descent (SI or BF) and what fraction of the seeds would be of the preferred seed type (100%, 75%, 50%, or 25%). This produced the eight different conditions studied in this experiment, and the dependent variable would be the average measure of the number eggs per a bean (not considering those that have no eggs) and of each bean type. These measurements would be recorded within an hour of preparing the plates as well as twenty-four hours later. With the measure of the average number of eggs per a bean, we learn more about the oviposition behavior of whether the conditions promote one egg to one bean or multiple eggs to one bean.…

    Determining the affects of natural selection on gall fly (Eurosta) larvae from different predators Ariel O’Neil Biology 1020H Abstract This lab was done with the objective of determining if directional selection causes early larvae death in the gall fly. By first examining the parasitoid wasp and birds predatory actions we can hypothesize and predict the smaller galls will be most likely to survive directional selection.…

    The Round Goby

    The data shows that once the round goby was introduced to the ecosystem the native species began to decline. The four native species in lab were perch, bass, bluegill, and walleye. Each species had to use a different utensil to collect food. The perch used one plastic spoon, the bass used two knives, the bluegill used one fork, and the walleye used two forks. In graph one it is shown that the smallmouth bass still survived greatly even with the round goby in the ecosystem.…

    Dottus Variegatus Essay

    Ten differing phenotypes of Dottus variegatus will be placed randomly in a colorful board to simulate a population in its environment. The total population includes 100 organisms with 10 representing members of each phenotype. The predator will decimate 25% of the population. Based on which colors experienced high or low levels of predation, the hypothesis that brighter colors will be selected against is tested. The ‘predator’ looks away while another person randomly scatters the 100 dots.…

    Acheta Domesticus Observation Report

    In order to test our null hypothesis, we created an experiment that allowed us to observe the behavior of Acheta domesticus (domestic crickets). For this experiment, we set up a choice chamber that would contain lettuce on one side and banana on the other. The transparent chambers allowed us to observe the crickets without disturbing them and without misplacing them. This type of observation would be considered focal sampling as we were observing the behavior of one cricket at a time for 2 minutes. We conducted a total of ten trials, through which the sex of the cricket(female), the number of crickets (1 at a time), the banana, the lettuce, and wax paper were all kept constant.…

    In the various chapters that we have gone through in this class, we have looked at various things in the environment that can alter how an animal acts, grows, and evolves. Like in Chapter 51 when we learned about animal growth and development. Or, Chapter 52 when we learned about “learned behaviors” like the Pavlov’s dog experiment and the “innate behaviors” of the female and male moths. The things that we learned in this class helped us to pick our experiment.…

    Natural Selection Lab Report

    The natural simulation done in class was a good representation natural selection in the wilderness. The four things that Darwin identified that must be present in order for natural selection to occur are genetic variation, overproduction of offspring, struggle for existence, and differential survival and reproduction. This activity demonstrated all these factors except genetic variation. For over production of offspring, the beans’ populations were multiplied by three after every round. This is because out of all beans, many will not survive the round, and so more beans needed to be present than the projected amount to survive.…

    Mealworm Experiment

    In the data table, each of the stimuli, including the control group without a stimulus, will be written in the left hand column under the title “stimulus”. Next to the stimulus column, there will be three columns titled “number of mealworms in stimulus chamber after 1 minute”, “number of mealworms in stimulus chamber after 2 minutes”, and “number of mealworms in stimulus chamber after 3 minutes”. Under each of the three columns relating to the minutes passed, the corresponding data will be collected for each stimulus. The control group is when no stimuli will be placed in the chamber opposite the mealworms and the number of mealworms in the chamber where there was no stimulus will be collected. The constants in the experiment are the…

    Natural Selection Dbq

    In the period from 1860-1900, Darwin developed his theory of natural selection. Natural selection was the idea that a dominant species would overcome all the rest. This sparked many ideas and philosophies, such as a weakening in the church, the rise of Social Darwinism, and a surge of new ideas and thought. The church had always been the lead in the sciences of the day, but when scientists started to challenge the church, their strength began to falter.…

    Darwin's Theory Of Evolution And Natural Selection

    Writing Assignment #1 Lasiognathus dinema There are a couple misconceptions you might have about evolution and natural selection. The strongest and most important organisms do not survive over the generations. Although evolution occurs due to fitness in an individual or individuals of a species, an organism cannot survive over generations. Fitness is achieved through variations in populations of species through genetic differentiation (Scottville “n.d.”). Since the life cycle of all living organisms is to be born, survive, mate, and die, it is impossible for an organism to live through several generations.…

    Darwin's Natural Selection Theory: Survival Of The Fittest

    Darwin’s idea has been born as an answer to questions in biology. He as the father of evolution contributed the most to our modern science. Even in this present his theories such as natural selection is still used, like a simple mathematical equation. We all know that two plus two equal four, however, did we ever question why? Taking this in consideration, his natural selection theory was based on idea:” Survival of the Fittest”.…
