Please Highlight or type answers in a d i f f e r e n t c o l o r. What are the 4 components of natural selection? Natural selection occurs if four conditions are met: reproduction, heredity, variation in physical characteristics and variation in number of offspring per individual. Some examples of variation would be: height, able to roll tongue, hair color, eye color, or attached/unattached earlobes. The Natural Selection virtual lab allows students the opportunity to investigate into how natural selection leads to the predominance of certain traits in a population, and the suppression of others. This evidence comes out of the Earth's crust. Define variation. Quality selection of science lab glassware designed to address accuracy and safety. Natural selection is a process which predicts that only those individuals which demonstrate more adaptive features will increase their reproductive fitness.

It is important to note that an individual does not evolve. If the frequencies of traits in a population change purely by chance , then genetic drift has occurred. How did a different type of environment affect natural selection of the prey population? What happened when the prey were living in the environment made up of the darker wild rice compared to the white rice environment? What would happen if a non-visual predator moved in, such as one that hunts at night using smell?. We assigned students to treatments (the physical or virtual simulation activity) by section and assessed their understanding of natural selection using a multiple-choice pre-/post-test and short-answer responses on a post-lab assignment. Charles Darwin, in modeling natural selection, used the artificial selection of pigeons to illustrate how selection can, over time, modify populations of living things. The environmental selection pressures, (food availability in space and time, mediated by competition), determine the survival rate or “fitness” of individual organisms. Introduction Biological evolution can be defined as the change in the frequency of genetic traits in a population over time. Natural Selection Simulation Activity.

(Rocky, Desert, Grasslands & Urban) and be sure to start with each possible allelic frequency provided. Natural Selection: The individuals that are most adapted to environment are the ones that are most likely to survive, reproduce, and pass on their genes to the next generation. The key distinction is that in genetic drift allele frequencies change by chance, whereas in natural selection allele frequencies change by differential reproductive success.

Those traits will then be passed on to the next generation, and over time the characteristics of the population will change or evolve (so that the majority of organisms. The selective pressures felt by populations are usually weak from one generation to the next, which is why the fourth element, time, is important. The specific effect of natural selection depends on the fitness of each specific genotype. 14 Discuss mechanisms of evolutionary change other than natural selection such as genetic drift and gene flow.
