Evolution
Explore the science of evolution, from natural selection and adaptation to speciation and phylogenetics. These quizzes help you review key mechanisms, classic evidence, and modern evolutionary thinking in a clear, practice-focused format.
Quizzes
Natural selection: fitness, trade-offs, and adaptation
Test how well you understand natural selection through the lens of fitness, trade-offs, and adaptation. You’ll sort out what selection can and can’t do, interpret evolutionary scenarios, and connect traits to survival and reproduction. Great for students who want clearer intuition and fewer textbook traps.
Evolutionary evidence: fossils, homology, and biogeography
Test how well you can interpret the key lines of evidence for evolution—from fossils and transitional forms to homology and biogeography. Questions mix concepts with quick scenarios, so you’ll practice linking observations to evolutionary explanations. Choose your preferred difficulty and number of questions to match your study goal.
Speciation: isolation, divergence, and hybrids
Explore how new species form when populations split, adapt, and sometimes reconnect. This quiz covers geographic and reproductive isolation, genetic divergence, and what hybrids reveal about species boundaries. Expect a mix of classic concepts and real-world examples from across evolution.

What you’ll practice
These Evolution quizzes focus on the core ideas behind how populations change over time, including natural selection, genetic drift, mutation, and gene flow.
You’ll also review speciation, common ancestry, and how scientists use fossils, comparative anatomy, and DNA data to infer evolutionary relationships.
How the quizzes work
Each question has 4 answer options, and there’s no timer, so you can think through scenarios and definitions at your own pace.
Quizzes vary in length and difficulty, mixing quick concept checks with more detailed questions that require interpreting examples, data, or evolutionary outcomes.
Helpful facts and context
Evolution acts on populations rather than individuals, and it’s driven by changes in allele frequencies across generations. Many well-known examples (like antibiotic resistance) are rapid evolutionary responses to selection pressures.
- Identify mechanisms of evolution and when each applies
- Distinguish homologous vs. analogous traits and what they imply
- Interpret simple phylogenetic trees and shared derived characters
- Connect evidence from fossils, anatomy, and genetics to common ancestry
- Apply Hardy–Weinberg conditions to recognize when evolution is occurring
Tips for better results
If a question feels tricky, look for what level it’s asking about (gene, individual, population, or species) and which mechanism best explains the change.
Re-taking a quiz after a break can help reinforce vocabulary (fitness, selection pressure, bottleneck, founder effect) and improve accuracy on similar question types.
