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.

This 13-minute video lesson looks at the science of taxonomy and where humans fit into the tree of life. [Biology playlist: Lesson 62 of 71].

By the end of this section, you will be able to:Identify and describe the properties of lifeDescribe the levels of organization among living thingsRecognize and interpret a phylogenetic treeList examples of different sub disciplines in biology

Biology for AP® Courses covers the scope and sequence requirements of a typical two-semester Advanced Placement® biology course. The text provides comprehensive coverage of foundational research and core biology concepts through an evolutionary lens. Biology for AP® Courses was designed to meet and exceed the requirements of the College Board’s AP® Biology framework while allowing significant flexibility for instructors. Each section of the book includes an introduction based on the AP® curriculum and includes rich features that engage students in scientific practice and AP® test preparation; it also highlights careers and research opportunities in biological sciences.

This site contains user-friendly tools to launch DNA database searches, statistical analyses, and population modeling from a centralized workspace. Educational databases support investigations of an Alu insertion polymorphism on human chromosome 16 and single nucleotide polymorphisms (SNPs) in the human mitochondrial control region.

Students in this lesson will investigate the differences in avian beaks and how they are used to benefit their species and lifestyle. There is an introductory portion, a lab portion, a compare and contrast portion and conclusion/reflection. 

In this video, Jonathan joins Charlie Donilon on his shark charter boat in Rhode Island, Massachusetts, and learns about how shark tagging has shed light on the biology of and behavior of Blue sharks. Tagging has shown that these incredible swimmers actually migrate completely across the Atlantic ocean. Jonathan tries his hand at tagging a shark and then swims with Blue sharks. We also learn that Blue sharks are not nearly as vicious as they have been reputed to be, and the divers are actually able to pet the sharks! Please see the accompanying study guide for educational objectives and discussion points.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"Bogs are unique ecosystems, which have important ecological functions in carbon storage, climate stability, water quality, and biodiversity. The bog microbiome, composed mostly of bacteria that live in association with bog plants, plays key roles in these functions. However, the differences in associated bacteria between vascular plants and the non-vascular bryophytes that predominate in bogs remain unclear. Researchers recently used shotgun metagenomics to investigate the microbes associated with 12 representative bog species. Vascular plants tended to be colonized by specific bacteria, while bryophytes exhibited greater bacterial species richness and diversity. The two plant groups also had different marker species. The gene profiles of vascular plant- and bryophyte-associated microbes revealed functional differences, including differences in nitrogen cycling..."

The rest of the transcript, along with a link to the research itself, is available on the resource itself.

Submitted as part of the California Learning Resource Network (CLRN) Phase 3 Digital Textbook Initiative (CA DTI3), CK-12 Foundation’s high school Biology FlexBook covers cell biology, genetics, evolution, ecology, botany, zoology, and physiology. This digital textbook was reviewed for its alignment with California content standards.

CK-12’s Life Science delivers a full course of study in the life sciences for the middle school student, relating an understanding of the history, disciplines, tools, and modern techniques of science to the exploration of cell biology, molecular biology, genetics, evolution, prokaryotes, protists,fungi, plants, animals, invertebrates, vertebrates, human biology, and ecology. This digital textbook was reviewed for its alignment with California content standards.

Starting from the Big Bang Theory to the concept of the accelerating expansion of the universe, this Mini Lecture explores the evolutionary origin and development of the universe. Historical as well as up-to-date lecture snippets of the physicists Brian Schmidt, George Smoot and John Mather, all held in Lindau, illustrate the concepts used to analyze the universe.

What cellular evidence do we have to construct evolutionary trees and believe that all life on Earth shares a common ancestry?

This is the second in a series of modules which detail the research of Charles Darwin and evolutionary theory. This module continues with a discussion of the processes that led to Darwin's formulation of the theory of natural selection.
