Finches on the Galapagos Islands have evolved to exploit almost every possible niche. This diagram shows the range of food sources available on the island and the different beak shapes adapted to exploit each of them.

The National Humanities Center presents collections of primary resources compatible with the Common Core State Standards - historical documents, literary texts, and works of art - thematically organized with notes and discussion questions. Topics discussed in this unit include the following: Becoming Modern: America in the 1920s: Religion & Science. Includes a collection of commentaries on the religion-science debate of the 1920s, followed by a Felix the Cat cartoon where he goes to Africa to look for proof of Darwin's theory of evolution.

This pathway explores how physical features of a species can change over time in response to environmental factors influencing survival. Learn about well known case studies like Darwin's finches and peppered moths, and conduct your own investigations through simulations.

This video segment from Evolution: "Darwin's Dangerous Idea," together with interviews with Daniel Dennett and James Moore, depicts Darwin struggling with publicizing his revolutionary theory.

This site from Palomar College contains a quiz that provides a nice review of the historyof Darwin's work and natural selection. Providesfor immediate feedback as soon as an answer is entered.

This pathway explores the concepts of natural selection and evolution of populations. Stories from scientists sharing their perspective on this topic and their research are embedded throughout the pathway.

This video segment from Evolution: "Darwin's Dangerous Idea" illustrates the remarkable camouflage of a praying mantis against its leafy backdrop.

This video from Evolution highlights Charles Darwin's personal struggle to bring to light his theory of evolution through natural selection.

Introduction to how groups of organisms evolve and how natural selection can lead to evolution. [17:39]

Khan Academy learning modules include a Community space where users can ask questions and seek help from community members. Educators should consult with their Technology administrators to determine the use of Khan Academy learning modules in their classroom. Please review materials from external sites before sharing with students.

The resource discusses the intelligent design. Some topics included are defining science, evolution, Darwin's prediction, and the Wedge strategy. The activity includes video and audio extras consisting of an interview with Judge Jones and the evolution of a species.

This documentary film [02:00:00] examines Darwin's insights and discusses how new breakthroughs in science are unlocking answers to riddles that Darwin couldn't answer. (29 December 2009)

When the "Origin of Species" was published in 1859, the ambitions and scopes of science were dramatically expanding. "Origin of Species" marked the transition of biology from a prescience to a science. [4:04]

This is the PBS Evolution site, including excellent information on Darwin, Change, Extinction, Survival, Sex, Humans, and Religion.

Psychology is designed to meet scope and sequence requirements for the single-semester introduction to psychology course. The book offers a comprehensive treatment of core concepts, grounded in both classic studies and current and emerging research. The text also includes coverage of the DSM-5 in examinations of psychological disorders. Psychology incorporates discussions that reflect the diversity within the discipline, as well as the diversity of cultures and communities across the globe.Senior Contributing AuthorsRose M.
