2011-02-27 · This interactive, modular lab explores how stickleback fish and fossil specimens are used to study evolutionary processes, with an emphasis on data collection and analysis. In this lab, students learn and apply techniques for analyzing the forms and structures of organisms — in particular, the pelvic structures of the threespine stickleback fish ( Gasterosteus aculeatus ), a model organism HHMI STICKLEBACK VIRTUAL LAB •Null Hypothesis The expected observation in nature. In a classroom, we expect there to be 50% boys and 50% girls. This virtual lab explores phenotypic, or trait, diversity in several related stickleback populations. It emphasizes quantitative measurement of phenotypic diversity and encourages thinking about the role of natural selection and genetic mechanisms of evolution. THE VIRTUAL EVOLUTION STICKLEBACK LAB Introduction: 1. Define “model organism.” A model organism is a species that has been extensively studied, usually because it is easy to maintain and breed in a laboratory setting and has particular experimental advantages.

To set the stage, it’s important to realize that from a stickleback’s perspective, “bird” is a four-letter word. Predation by diving birds like grebes and coots is commonplace in many freshwater stickleback populations. 2019-01-24 · De senaste tweetarna från @maccoll_lab New stickleback in the lab April 24th, 2016 / My research For my new research projects on the role of individuality in collective movements and decision making at the University of Konstanz, I have been getting new sticklebacks from the Bodensee.

Consequently, the material information derived in the experiment will enable the Back in the early 80s, Don McPhail worked on sticklebacks in Vancouver Island, and specifically in some intriguing lakes that had not one but two different species of sticklebacks in them. Ten years later, McPhail and Schluter would build on this research and help to catapult stickleback to the forefront of evolutionary biology. Answers - Virtual evolution stickleback lab 14.

The genotype for stickleback fish without pelvic spines (both absent and reduced fish in the virtual lab) is homozygous recessive. ANSWER KEY This virtual lab explores phenotypic, or trait, diversity in several related stickleback populations. It emphasizes quantitative measurement of phenotypic diversity and encourages thinking about the role of natural selection and genetic mechanisms of evolution. Stickleback, fossil, evolution, natural selection, variation, adaptation APPROPRIATE LEVELS The Virtual Stickleback Evolution Lab is appropriate for high school biology as an excellent companion to an evolution unit. Because the trait under study is fish pelvic morphology, the lab can also be used for lessons on vertebrate form and function. The lab includes several short videos explaining research methods and relating the evolutionary history of the stickleback fish.
