12.491 is a seminar focusing on problems of current interest in geology and geochemistry. For Fall 2005, the topic is organic geochemistry. Lectures and readings cover recent research in the development and properties of organic matter.

Biology 2e is designed to cover the scope and sequence requirements of a typical two-semester biology course for science majors. The text provides comprehensive coverage of foundational research and core biology concepts through an evolutionary lens. Biology includes rich features that engage students in scientific inquiry, highlight careers in the biological sciences, and offer everyday applications. The book also includes various types of practice and homework questions that help students understand—and apply—key concepts. The 2nd edition has been revised to incorporate clearer, more current, and more dynamic explanations, while maintaining the same organization as the first edition. Art and illustrations have been substantially improved, and the textbook features additional assessments and related resources.

By the end of this section, you will be able to do the following:

Compare homologous and analogous traits
Discuss the purpose of cladistics
Describe maximum parsimony

By the end of this section, you will be able to do the following:

Discuss the need for a comprehensive classification system
List the different levels of the taxonomic classification system
Describe how systematics and taxonomy relate to phylogeny
Discuss a phylogenetic tree's components and purpose

By the end of this section, you will be able to do the following:

Describe horizontal gene transfer
Illustrate how prokaryotes and eukaryotes transfer genes horizontally
Identify the web and ring models of phylogenetic relationships and describe how they differ from the original phylogenetic tree concept

Biology is designed for multi-semester biology courses for science majors. It is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand. To meet the needs of today’s instructors and students, some content has been strategically condensed while maintaining the overall scope and coverage of traditional texts for this course. Instructors can customize the book, adapting it to the approach that works best in their classroom. Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand—and apply—key concepts.

By the end of this section, you will be able to do the following:

Identify and describe the properties of life
Describe the levels of organization among living things
Recognize and interpret a phylogenetic tree
List examples of different subdisciplines in biology

This is the second in a series of majoręs biology classes covering the principles of biology. The course is an integrated study of basic concepts concerning animal biology emphasizing animal evolution, diversity, phylogeny and a comparative look at general principles of animal form and function. This course is a lab science class and students will be required to participate in weekly lab activities and document their lab work for successful course completion.

Biol & 213 is the third course of a year-long series of biology courses for Biology majors. The first third of the course surveys prokaryotes, protists, fungi, and plants, focusing on diversity, evolution, and life cycles from an evolutionary perspective. We will then describe plant anatomy, physiology, growth, responses to the environment, and reproduction, emphasizing flowering plants. We will finish with ecology, focusing on population, and community ecology and expanding outward to ecosystems and the introduction of biodiversity and conservation.
