Natural Selection Virtual Lab Report

Natural Selection Virtual Lab Report Instructions: As you complete each slide of the Natural Selection Virtual Lab Activity, please fill in this lab report with the appropriate information and data. Objective(s): In this lab, we will learn to: ● identify different types of evolutionary adaptations ● explain ways in which genetic variation and environmental factors contribute to evolution by natural selection and diversity ● simulate the effects of natural selection and genetic variation under specific environmental conditions= Hypotheses: 1. The environment with snow will have an increase in population of white rabbits over time. 2. the Environment with brown woods will have a decrease in population of white rabbits over time. Variables: ● IV- control of predatory bird ● DV- number/color of fur of rabbits that survive over generation ● con- con-amount of rabbits initially/Environment Materials: 1. The Natural Selection Virtual Lab Activity 2. Natural Selection Virtual Lab Report Procedures: The procedures are listed in Natural Selection Virtual Lab Activity. You do not need to include them here.

Why or why not? both of my hypothesis are correct because the charts show why its correct ● Using Table 1, which color rabbit had the higher rate of survival in the light-colored (white) environment? Explain why this occurred. the white rabbits because browns rabbits did not have a high percentage of surviving ● Using Table 2, which color rabbit had the higher rate of survival in the dark-colored (brown) environment? Explain why this occurred. the browns rabbits have a higher percentage of surviving ● What color rabbit seemed to camouflage the best in this snow habitat and why? the whites one because the snow and the rabbits are both white Questions Using what you have learned from the lesson and the virtual lab activity, answer the following questions in complete sentences. 1. How did the colors of each type of prey affect its population size over time? because they both are different color and likes differents seasons. 2. How do you predict the data would change if you continued? Explain your answer. i feel like the brown will effect because they like to come out in the warm and the white rabbits like to come out in the cold 3. What traits could help a predator be more “fit” to survive in each environment? Be specific. don’t eat the other animals you see all the time 4. Describe other adaptations besides color that could affect an individual’s survival. the other animals that prey on them 5. Explain what will happen if there are not enough resources to support the individuals in a species. they will all die because there is not enough of that species 6. This experiment tested natural selection, what could be another possible mechanism of evolution for the rabbits to evolve. population will help the rabbits evolve because there will be more rabbits
