Evolution Lab BIO/101 Pooja Thakur 7-23-12 Evolution Resulting From Natural Selection INTRODUCTION The Evolution Lab simulates environmental situations to determine effects on evolution over periods of time. This lab experiments with the evolution of finches on two different islands over 100‚ 200‚ and 300 years. By manipulating parameters that influence natural selection‚ the effects that natural selection have on the evolution process can be studied. HYPOTHESES • The size

Influencing Natural Selection Influencing Natural Selection BIO/101 Influencing Natural Selection Introduction/Purpose The purpose of this experiment is to test the hypothesis that small bird’s physical characteristics can greatly impact their species population growth over time. Using the Finch as a test subject for multiple trial runs on a simulated computer system we can alter the characteristics of the finch and run diagnostics for two completely different locations and set

Evolution Lab “Evolution by Natural Selection” The object of this experiment is to determine how changing the size of the beak of a finch will affect the population as well as the growth rate of the finch’s beak. The reason for the experiment is to evaluate evolution and how it affects the finch’s population‚ and how natural selection is always present in life. In this experiment I will show that the finch will continue to evolve until its beak has reached the optimal size for sustaining

Melissa Morales Bios 101 Spring 2013 Demography- Human Life History Introduction Demography is the study of human populations. It studies the size‚ composition and distribution of a population‚ and the process through which a population changes. Demography allows us to track changes over time and to depict how different periods in history change population dynamics. Births‚ deaths‚ migration and emigration‚ jointly produced the change within a population (Biological Science). Demography

Ksenia Semina Evolution Lab ARR 3 Blast Lab Analysis: Gene 1: The 4 organisms that were looked at in the Gene 1 are bird‚ vertebrate‚ rodent and bony fish. From the Blast result the most similar gene sequence to the gene of the gene of interest is Gallus gallus collaged which is also a bird. They are the most similar because the Gallus has the highest max score out of all other genes and 100% for the ident and there is no difference in the e-value. The species is located at the bird’s branch

Evolution Lab Report Marcos Chapa July 3‚ 2013 BIO 101 Rebecca Avants The purpose of the lab I have conducted is to analyze how altering the finch’s environment would affect the evolution of the finches by isolating each population of finches from each other‚ placing them each on a different island. This influence on the species by the environment is called allopatric speciation. One population of the finches that are located Darwin Island‚ which is 1 km‚ and the other population of finches

Bio Lab Report Erica Patterson September 10‚2013 Intro to cellular and molecular Biology Lab Abstract: In the Biology Laboratory Manual by Darrell S. Vodopich and Randy Moore are results to a similar experiment. The studied the hypothesis of carbon dioxide production by yeast fed sugar is not significantly different than the carbon dioxide production by the yeast fed in protein. Their hypothesis is the one that has helped formulate ours. We also will be answering the same to questions “What
