This activity explores images of stickleback fish, some with spines and some without spines, which serve as phenomena for learning about gene regulation and natural selection.
In this activity, students collect and analyze evidence for each of the major conditions for evolution by natural selection to develop an explanation for how populations change over time.
This video focuses on the front lines of the 2013–2016 Ebola outbreak in West Africa and explains how scientists monitored the evolution of the virus by analyzing its genome.
A number of interactive questions are embedded within the short film The Making of the Fittest: Evolving Switches, Evolving Bodies, which illustrates how mutations in gene regulatory regions can result in the evolution of major anatomical features.
Several questions are embedded within the short film The Making of the Fittest: Got Lactase? The Co-evolution of Genes and Culture, which explores the genetics of lactase persistence and evolution of the trait in some human populations.
A number of interactive questions are embedded within the short film The Biology of Skin Color, which explores the hypothesis that the variations in skin color in humans arose as adaptations to the intensity of ultraviolet radiation in different parts of the world.
In this case study, students explore the story of the evolution of lactase persistence based on the short film Making of the Fittest: Got Lactase? The Co-evolution of Genes and Culture and makes connections between genotype, phenotype, and culture using graphical analysis skills.
This film explores the hypothesis that different tones of skin color in humans arose as adaptations to the intensity of ultraviolet radiation in different parts of the world.
A number of questions are embedded within the short film The Making of the Fittest: The Birth and Death of Genes, which illustrates how gene duplications and mutations have led to remarkable physiological adaptations in Antarctic fish.
Several questions are embedded within the short film The Making of the Fittest: Natural Selection and Adaptation, which uses the rock pocket mouse as a living example of natural selection.
