Anatomical Evidence for Evolution is a Grade 7 Science worksheet focused on biological evolution, unity and diversity, and the use of comparative anatomy to examine evolutionary relationships.

Build Understanding Through Comparative Anatomy

Students examine homologous, analogous, and vestigial structures and consider how similarities and differences in anatomy can provide evidence for common ancestry and adaptive divergence. The lesson also connects anatomical evidence with fossil evidence and genetic information when studying evolutionary relationships.

What Students Do

• Read an informational passage explaining comparative anatomy and evolutionary evidence.
• Answer multiple-choice questions about homologous structures, analogous structures, vestigial structures, common ancestry, adaptations, and supporting evidence.
• Evaluate true-or-false statements about anatomical evidence and evolutionary relationships.
• Write short answers explaining how homologous and analogous structures differ and why scientists combine different types of evidence.
• Interpret a labeled diagram comparing structural patterns.
• Categorize examples according to the type of anatomical evidence described.

Included Teacher Support

• Student worksheet with Student Notes lines at the bottom
• Answer Key PDF
• Teacher Guide with Learning Objectives, Teaching Tips, Discussion Questions, and Common Mistakes

Classroom Application

Use this evolution worksheet for classroom instruction, independent practice, review, or assessment within a Grade 7 biology or evolution unit. The combination of reading, selected-response questions, written responses, diagram interpretation, and categorization gives students multiple ways to work with the vocabulary and evidence used in comparative anatomy.

The resource is identified with the NGSS framework and focuses specifically on how anatomical similarities and differences can be interpreted alongside fossil and genetic evidence when examining evolutionary relationships.
