Evidence for Evolution

Evidence for Evolution starts at 8 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Evidence for Evolution.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 11
Describe how artificial selection demonstrates the principles of evolution.
Describe how biogeography supports the theory of evolution.
Describe how comparative anatomy can be used to determine evolutionary relationships.
Describe how molecular biology provides evidence for evolution.
Describe how the fossil record provides evidence for evolution.
Describe one example of a vestigial structure in humans and its evolutionary significance.
A scientist discovers a fossil with characteristics intermediate between reptiles and birds. What type of evidence does this fossil provide for evolution, and why is it significant?
Context: In a population of insects, a pesticide is introduced. Over several generations, most insects become resistant to the pesticide.
Question: Explain how this scenario provides evidence for the process of natural selection and evolution.
Which of the following best describes analogous structures? (1) Structures with similar function but different evolutionary origins (2) Structures with similar structure and origin (3) Structures that are no longer functional (4) Structures found only in fossils
Which of the following best explains why island species often differ from their mainland relatives? (1) Genetic drift (2) Biogeographical isolation (3) Artificial selection (4) Mutation only
Which of the following is an example of a homologous structure? (1) Butterfly wing and bat wing (2) Whale flipper and human arm (3) Bird beak and turtle shell (4) Fish fin and octopus tentacle
Which of the following is an example of a vestigial structure? (1) Human arm (2) Whale pelvis (3) Bird beak (4) Fish gills
Fill in the blank: The process by which humans breed plants and animals for particular genetic traits is called ________.
Fill in the blank: The process by which unrelated organisms independently evolve similarities when adapting to similar environments is called ________ evolution.
Fill in the blank: The similarity in early embryonic stages of fish, birds, and humans suggests ________ ancestry.
Fill in the blank: The study of the distribution of species and ecosystems in geographic space and through geological time is called ________.
DNA sequence similarities between humans and chimpanzees provide molecular evidence for evolution. Yes or No?
True or False: All homologous structures have the same function in different species.
True or False: Biogeography supports evolution by showing that similar environments can lead to similar adaptations in unrelated species.
True or False: Comparative embryology shows that embryos of different species often resemble each other in early stages.
