About
This quiz comprehensively covers evolution and natural selection concepts appropriate for 9th grade high school biology. The questions assess students' understanding of fundamental evolutionary principles including adaptations, natural selection mechanisms, evidence for evolution, and comparative anatomy. Students need to demonstrate mastery of key vocabulary such as fitness, vestigial structures, homologous structures, and artificial selection, while also applying conceptual knowledge to analyze scenarios like pesticide resistance in insects and predator-prey relationships. The quiz requires students to distinguish between different types of evolutionary evidence including fossil records, molecular comparisons, and anatomical structures, as well as understand how genetic variation and environmental pressures drive evolutionary change over time. Created by Becky Thompson, a Biology teacher in the US who teaches grade 9. This evolution review quiz serves multiple instructional purposes throughout a unit on natural selection and evolutionary theory. Teachers can effectively use this assessment as a comprehensive review before a unit exam, assign it as homework to reinforce classroom learning, or implement it as a formative assessment to identify areas where students need additional support. The variety of question formats and complexity levels makes it suitable for differentiated instruction and helps students prepare for standardized biology assessments. This quiz aligns with NGSS standards HS-LS4-1 (communicating scientific information about common ancestry), HS-LS4-2 (constructing explanations for adaptation), and HS-LS4-3 (applying mathematical concepts to support natural selection), providing comprehensive coverage of essential evolutionary concepts that form the foundation of modern biological understanding.

Some organisms have structures or organs that seem to serve no useful purpose. For example, humans have a tailbone at the end of the spine that is of no apparent use. However, the tailbone of a possum, and some monkeys, is more fully structured and has a definite purpose. What conclusion is supported by this?
Possums and monkeys are more closely related to each other than to humans
Possums, monkeys and humans have a common ancestor
Monkeys and humans do not share a common ancestor
These analogous structures do not support any evolutionary relationship

Vestigial structures can be described as
Structures that had a purpose in an ancestral organism, but not in the evolved organism
Structures that never had a purpose in this or ancestral organisms
Structures that have atrophied in an individual because they have not been used much in their lifetime

According to Darwin’s theory of natural selection, individuals who survive are the ones best adapted for their environment. Their survival is due to the
possession of adaptations developed through use.
possession of inherited adaptations that maximize fitness.
lack of competition within the species.
choices made by plant and animal breeders.

Which statement about the members of a population that live long enough to reproduce is consistent with the theory of evolution by natural selection?

They are the ones that are best adapted to survive in their environment.
They will perpetuate unfavorable changes in the species.
