Students toss coins to determine what traits a set of mouse parents possess, such as fur color, body size, heat tolerance, and running speed. Then they use coin tossing to determine the traits a mouse pup born to these parents possesses. Then they compare these physical features to features that would be most adaptive in several different environmental conditions. Finally, students consider what would happen to the mouse offspring if those environmental conditions were to change: which mice would be most likely to survive and produce the next generation?

The course Bio-Inspired Design gives an overview of non-conventional mechanical approaches in nature and shows how this knowledge can lead to more creativity in mechanical design and to better (simpler, smaller, more robust) solutions than with conventional technology. The course discusses a large number of biological organisms with smart constructions, unusual mechanisms or clever sensing and processing methods and presents a number of technical examples and designs of bio-inspired instruments and machines.

Patterns of diversity, ecology, and evolutionary biology. Emphasis is on the Tree of Life and how its members are distributed and interact. Partial Course.

Patterns and processes of evolution. How evolution and natural selection are reflected in the similarities and differences of organisms.

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.

Biology is the science that studies life, but what exactly is life? This may sound like a silly question with an obvious response, but it is not always easy to define life. For example, a branch of biology called virology studies viruses, which exhibit some of the characteristics of living entities but lack others. It turns out that although viruses can attack living organisms, cause diseases, and even reproduce, they do not meet the criteria that biologists use to define life. Consequently, virologists are not biologists, strictly speaking. Similarly, some biologists study the early molecular evolution that gave rise to life; since the events that preceded life are not biological events, these scientists are also excluded from biology in the strict sense of the term. From its earliest beginnings, biology has restled with these questions: What are the shared properties that make something “alive”? And once we know something is alive, how do we find meaningful levels of organization in its structure?

By the end of this section, you will be able to:Describe the features that characterized the earliest animals and when they appeared on earthExplain the significance of the Cambrian period for animal evolution and the changes in animal diversity that took place during that timeDescribe some of the unresolved questions surrounding the Cambrian explosionDiscuss the implications of mass animal extinctions that have occurred in evolutionary history

By the end of this section, you will be able to:Describe pathways of species evolution in hybrid zonesExplain the two major theories on rates of speciation

By the end of this section, you will be able to:Describe how the present-day theory of evolution was developedDefine adaptationExplain convergent and divergent evolutionDescribe homologous and vestigial structuresDiscuss misconceptions about the theory of evolution

By the end of this section, you will be able to:Compare homologous and analogous traitsDiscuss the purpose of cladisticsDescribe maximum parsimony

By the end of this section, you will be able to:Discuss the need for a comprehensive classification systemList the different levels of the taxonomic classification systemDescribe how systematics and taxonomy relate to phylogenyDiscuss the components and purpose of a phylogenetic tree

By the end of this section, you will be able to:Describe horizontal gene transferIllustrate how prokaryotes and eukaryotes transfer genes horizontallyIdentify the web and ring models of phylogenetic relationships and describe how they differ from the original phylogenetic tree concept

This course is an introduction to organismal biology with a focus on evolution, the diversity of life and ecology. Major topics include the processes and outcomes of microevolution, macroevolution and the history of life, a survey of the major groups of eukaryotic organisms, basic plant and animal structures and their functions, and ecology. Students engage the scientific method by designing, conducting and evaluating laboratory experiences that include selected topics in seedless plants, seed plants, invertebrates, chordates, animal behavior, ecology and evolution. Field-based lab experiences train students to observe, collect, measure and monitor organisms in the wild.
