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

Evolution Lab A. 1. a. The default value of 20 cm of rainfall is relatively low compared the range that the island may receive‚ which is anywhere between 0 cm to 100 cm. b. From an average of 20 cm of rainfall I would expect more hard seeds to be produced. 2. a. The beak size of 12 mm is relatively shallow compared to the available range from 10 mm to 30 mm. b. The shallow beak size of 12 mm is not suited for the hard seeds that are available because of the low rainfall of 20 cm.

Charles Robert Darwin has had the greatest influence on the world by proving the evolution of living things. Charles Darwin had first noticed the similarities of plants and animals when he took a five-year cruise on the H.M.S. Beagle‚ which was available to him through a friend from school. During the cruise Charles Darwin started becoming interested with the similarities between the plants and animals that were similar on different islands with similar climates‚ so he decided to study them more

Title: The Beaks of Finches # of the Lab: Purpose: The purpose of this lab is to be able to work with different tools that will serve to model finch “beaks” and compete with other “finch” species to see which “beak” best adapted for obtaining specific food. Materials: 1 small plastic dish or cup‚ 1 large non-breakable dish‚ 1 tool to serve as a “beak”‚ large seed‚ small seed‚ 2 pairs safety goggles Procedure: See Lab # The Beaks

______________________ LAB ____. ANATOMICAL EVIDENCE OF EVOLUTION In our studies of the anatomy and development of animals we have discovered that many living creatures that look quite different on the surface have similarities underneath their skin that suggest that they are related to each other. This is evidence that living creatures have evolved‚ or gradually changed over time. In this lab‚ you will learn about homologous‚ analogous‚ and vestigial structures and their value as evidence for evolution. INSTRUCTIONS

that’s changed; It’s all living things. This change over time or ‘development’ is called evolution. Evolution is the change of (heritable) traits in different organisms over time. If you’re thinking apes becoming humans you’re already wrong. There’s even evidence of evolution like fossils‚ DNA samples‚ similarities in bone structure‚ and even vestigial organs. The purpose of this lab is to see how evolution works and whether it is a reliable theory. Hypothesis: If there are 11 skulls that all have

Dear Mr. Charles Darwin‚ Greetings Mr. Charles Darwin! You are probably thinking‚ "Who in the name is this and what is with apparel?." Well my name is Tiffany and I came from the future! How I came from the future would be a different story but sir‚ I was handed a task to explain to you some amazing evidence after your research. Before I even start on explaining to you how people built information off your building blocks‚ let me explain what Mr. Mendel did. Mendel was a researcher on genetics

Summary Charles Darwin was born on February 12‚ 1809‚ in Shrewsbury‚ England and died at the Down House in Kent on April 19‚ 1882. He was born to Robert and Susannah Darwin. In 1831‚ Darwin was offered a position on board the HMS Beagle. He eagerly accepted the opportunity and spent the next five years on board the Beagle. Henslow and other geologists‚ zoologists‚ and botanists were fascinated by the specimens he had collected. In 1839‚ Darwin married Emma Wedgwood‚ his cousin

Alfred Russell Wallace‚ a naturalist -an expert in or student of natural history- Born in Usk‚ United Kingdom on January 08‚ 1823‚ made two expeditions to South America and Indonesia and formulated the modern theory of evolution! Wallace met Charles Darwin at scientific meetings and eventually shared ideas and became friends. Wallace wrote letters to Darwin about this as Darwin also stumbled upon the same results and therefore listed Wallace as an author to the theory of modern evolution on July 1‚
