Evidence for Evolution
Biology ⇒ Evolution and Diversity
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 9
Describe how biogeography supports the theory of evolution.
Describe how comparative anatomy provides evidence for evolution.
Describe how embryology provides evidence for evolution.
Describe what is meant by a transitional fossil and give an example.
Describe what is meant by homologous structures and give an example.

Fill in the blank: ________ structures have similar functions but different evolutionary origins.
Fill in the blank: The ________ is the preserved remains or traces of an organism from the past.
Fill in the blank: The ________ of a species can be traced through changes in its fossils over time.
Fill in the blank: The ________ record provides a timeline of life on Earth through preserved remains or traces of organisms.
True or False: All living things use the same genetic code, which supports the idea of common ancestry.
True or False: Analogous structures indicate a close evolutionary relationship between species.
True or False: Fossils can show the transition from aquatic to terrestrial life.
True or False: Fossils provide evidence of how organisms have changed over time.
