AP biology buffs define vocabulary terms and answer critical-thinking questions about evolutionary trends. They compare macroevolution to microevolution, differentiate ploidy possibilities, explain isolation barriers, and more....

Students describe the anatomy of a virus. For this biology lesson, students compare and contrast the characteristics of bacteria and viruses. They discover the genetic adaptations of viruses over time.

Lisa Peters presents macroevolution as a large-scale family tree in her book Our Family Tree: An Evolution Story. She suggests the process from single-celled organisms to modern-day humans, and learners explore new vocabulary...

Students consider two sets of simulated fossils (caminalcules) that are provided as cutouts. They arrange them on two time scales. One set produces a visual example of gradualism, the other shows punctuated equilibria.

Can your young biologists interpret population graphs, match macroevolution patterns and descriptions, and answer multiple choice questions about evolution? Find out with a comprehensive three-page quiz covering some specific examples of...

Scientists noticed animals with backbones share similar bone structure despite having different forms, such as fins, arms, and wings. Young scientists gain an appreciation for evolution by understanding the history of the theory. They...

Scholars take off on an interactive spaceship to explore a historical timeline of the big bang theory. They learn about the evolution of mammals and humans, the formation of stars and planets, and the chemical composition of the early...

What evidence supports the big bang theory? Individuals analyze scholarly resources about the the theory and develop arguments backed by evidence. They brainstorm, share ideas, watch a video, and read articles to complete a graphic...

Students compare/contrast the DNA sequence data of the rat GULO gene to the inactive human GULO gene. They translate and align the sequences, and propose a scenario to explain the occurrence of an inactive DNA sequence to that of an...

Students examine why some freshwater populations of stickleback fish.  In this macroevolution lesson students read a study packet then answer questions. 

Examples of natural selection over time will make the concept of evolution more clear to your students. This presentation is short but summarizes the mechanisms of isolation and selection clearly.  This presentation would be useful...

Students develop likely phylogenies for seven related populations of lizards living on the Canary Islands using real data. They organize charts, and record the data for geography, geology, morphology, and molecular genetics.

Students compare/constrast DNA sequence data for a portion of the rat GULO gene to the corresponding sequence in the inactive GULO gene in humans, chimpanzees, orangutans, and crab-eating macaques by identifying the shared sequences in...

Understand the difference between microevolution and macroevolution.

Review the process of species changing and evolving over time.

The concepts of microevolution and macroevolution are explained and a two-column table that compares them is presented.

Understand the large-scale processes of evolution.

What is evolution? This thorough site provides the basics of evolution focusing on the history of life, processes of evolution, microevolution, macroevolution, and more.

A collection of articles on evolutionary genetics focusing on the topics of phylogenetics, mutation and molecular population genetics, the genetics of speciation, genome evolution, and evolution and development. Learn how to read a...

[Free Registration/Login may be required to access all resource tools.] Constrasts gradualism and punctuated equilibrium.

[Free Registration/Login may be required to access all resource tools.] Introduction to macroevolution, microevolution, and population genetics.

Macroevolution and microevolution are defined, along with mutation, migration, genetic drift, and natural selection, which are "established mechanisms of evolutionary change."

Video discusses the concept of evolution and the five processes that can cause it to happen. [5:24] Includes a brief quiz and a list of additional resources to explore.
