The Making of the Fittest: Natural Selection and Adaptation In a complete story, from ecosystem to molecules, pocket mice show us how random changes in the genome can take many paths to the same adaptation—a colored coat that hides them from predators.Check out their other interesting films here: http://www.hhmi.org/biointeractive/Frequently asked questions about evolution: http://www.pbs.org/wgbh/evolution/library/faq/index.htmlEvolution: Fact and Theory: http://www.actionbioscience.org/evolution/lenski.html101 Reasons Why Evolution is True: http://ideonexus.com/2012/02/12/101-reasons-why-evolution-is-true/Evidence of Common Descent: http://en.wikipedia.org/wiki/Evidence_of_common_descentEvolution 101: http://evolution.berkeley.edu/evolibrary/article/evo_018 examples of evolution in action: http://listverse.com/2011/11/19/8-examples-of-evolution-in-action/15 Evolutionary Gems: http://www.nature.com/nature/newspdf/evolutiongems.pdfCopyright Disclaimer Under Section 107 of the Copyright Act 1976, allowance is made for \"fair use\" for purposes such as criticism, comment, news reporting, teaching, scholarship, and research. %%EOF Dr. Michael Nachman, working in the field and lab, has quantified predation on rock pocket mice Published August 2012 Revised October 2013 www.BioInteractive.org Page 1 of 4 QUIZ STUDENT HANDOUT The Making of the Fittest: Natural Selection and Adaptation A mutation is a random change to an organism’s DNA sequence.
