• [History of life: Grades 9-12] Present-day species evolved from earlier species; the relatedness of organisms is the result of common ancestry. (LS4.A)
• [History of life: Grades 9-12] Biological evolution accounts for diversity over long periods of time. (LS4.A, LS4.D)
• [History of life: Grades 9-12] Through billions of years of evolution, life forms have continued to diversify in a branching pattern, from single-celled ancestors to the diversity of life on Earth today.
• [History of life: Grades 9-12] Life forms of the past were in some ways very different from living forms of today, but in other ways very similar. (LS4.A)
• [History of life: Grades 9-12] Life on Earth 3.8 billion years ago consisted of one-celled organisms similar to present-day bacteria.
• [Evidence of evolution: Grades 9-12] The fossil record provides evidence for evolution.
• [Evidence of evolution: Grades 9-12] There are similarities and differences among fossils and living organisms.
• [Evidence of evolution: Grades 9-12] Similarities among existing organisms provide evidence for evolution. (LS4.A)
• [Evidence of evolution: Grades 9-12] There are similarities in the cell function of all organisms. (LS4.A)
• [Evidence of evolution: Grades 9-12] All life forms use the same basic DNA building blocks. (LS4.A)
• [Nature of science: Grades 9-12] A hallmark of science is exposing ideas to testing. (P3, P4, P6, P7)
• [Nature of science: Grades 9-12] Scientists test their ideas using multiple lines of evidence. (P6, NOS2)
• [Nature of science: Grades 9-12] Scientists use multiple research methods (experiments, observational research, comparative research, and modeling) to collect data. (P2, P3, P4, NOS1)
• [Nature of science: Grades 9-12] Scientists can test ideas about events and processes long past, very distant, and not directly observable.
• [Nature of science: Grades 9-12] The real process of science is complex, iterative, and can take many different paths.
• [Studying evolution: Grades 9-12] Our knowledge of the evolution of living things is always being refined as we gather more evidence.
• [Studying evolution: Grades 9-12] Our understanding of life through time is based upon multiple lines of evidence.
• [Studying evolution: Grades 9-12] Scientists use fossils (including sequences of fossils showing gradual change over time) to learn about past life.

This tutorial is fairly advanced and may be more appropriate for an AP biology course. The tutorial also has many nice tie-ins to concepts in genetics, such as DNA, RNA, and protein synthesis.
