Give your biology students a focused look at evidence for common ancestry with ninety questions built for real classroom use, whether you are starting a new unit or reviewing before a test.
The set includes questions like "How do homologous structures support the concept of common ancestry?", "Which is an example of a homologous structure?", and "How can molecular biology support the theory of common ancestry?"
Each worksheet reviews the same core ideas from a different angle. Use them across a week or unit so students see the material three times without it ever feeling repetitive.
This set is part of a standards aligned biology unit. The unit also covers Fossil Record and Evolution, Four Factors of Evolution, Genetic Variation and Selection, Trait Advantage and Statistics, Reproductive Success, and Natural Selection Explained, all in the same three worksheet format, so your classroom routine stays familiar while the topic changes.
Suitable for Grade 10 biology classes, and for review at any point in the school year. This set is aligned to NGSS standard HS-LS4-1.
