Evolution Lab
Count the traits, follow the selection and read the evolutionary tree.
Evolution Lab covers the evolution strand of a high school biology course, one idea at a time. It opens with variation: students count the traits in a drawn population, work out which traits are inherited and see how a new allele can appear through mutation. Then it moves on to natural selection, where a predator or a changing environment removes some individuals and the next generation is drawn from the counts.
Middle levels cover fitness, adaptation and the three kinds of selection, then speciation and reproductive isolation. The later levels turn to evidence for common descent, cladograms and allele frequencies, including Hardy-Weinberg for simple cases. Every population, count and sequence is original practice data made up for the game, and every picture is drawn from the same numbers as its question.
What children practice
- Count traits in a population and tell inherited traits from learned ones
- Explain how variation, inheritance and selection lead to change over generations
- Define fitness as offspring that survive, and tell directional, stabilizing and disruptive selection apart
- Describe reproductive isolation and how new species form
- Use fossils, homologous structures, DNA and cladograms as evidence for common descent
- Work with allele counts, p and q, and what makes frequencies change
Levels
- Variation: Traits and mutation
- Natural selection: Survival and offspring
- Fitness: Adaptation and kinds of selection
- Speciation: Reproductive isolation
- Evidence: Fossils, DNA and structures
- Cladograms: Reading evolutionary trees
- Allele frequencies: Hardy-Weinberg and change
- Course mix: Everything
How it works
- Eight levels run from variation to allele frequencies, and the last level mixes every kind of round with longer chains of steps.
- Rounds take several shapes: choose an answer, tap the parts of a drawing, sort cards into bins, match pairs, put steps in order or type a number on a keypad.
- Five correct answers and a short practice timer unlock the next level, so each level has to be earned in turn.
- A wrong answer gets a gentle nudge to try again, and Need a hint? gives up to three clues. After a correct answer a short note explains why.
Best for: A good fit for grades 9 to 12 in biology, and for anyone who wants to practice evolution before a unit test or a final.
Tip for parents: Ask your child to explain why a population evolves but a single animal does not. Listening for the words variation, inherited and offspring shows how well the idea has landed.
Questions parents ask
Are the populations and DNA sequences real data?
No. Every population, count, table and DNA sequence is invented for practice, so a student learns the method without needing to memorize a particular study. Cladograms are drawn from real family trees of vertebrates, primates and plants.
Does the game say that animals change because they need to?
No. It treats evolution as something that happens to populations over generations. Individuals with helpful traits leave more offspring, and no question suggests that an organism changes in order to survive.
How hard is the Hardy-Weinberg level?
Level 7 begins by counting alleles in a drawn population, then moves to the p and q equations for simple cases with clean numbers. The cards show p squared, q squared and 2pq, and no calculator is needed.
