How does comparative anatomy provide evidence of change through time?
Embark on an enlightening journey into the world of comparative anatomy with this interactive digital lesson. Designed to empower students with a deep understanding of how anatomy provides evidence for evolutionary change, it's a must-have addition to any biology curriculum.
1. Homologous Structures:
Students begin with an engaging overview of whale evolution, uncovering the fascinating reasons behind seemingly dissimilar organisms sharing homologous structures. They dive into a captivating picture puzzle, identifying homologous bones in the front limbs of various creatures and discerning their unique functions. Exploring the front limbs of ancient organisms, they make educated deductions about our common ancestry.
2. Analogous Structures:
Students embark on a comparative journey, scrutinizing wings in four distantly related organisms. They skillfully identify the bones responsible for flight in each, revealing the intriguing adaptations that enable flight across species.
3. Vestigial Structures:
Delving into the intricacies of human anatomy, students examine a comprehensive chart detailing various vestigial structures. Applying deductive reasoning, they complete a table detailing the vestigial structures present in humans, their ancestral functions, and the reasons for their current redundancy.
In a culminating online activity, students unravel the remarkable revelation that modern birds are, in fact, dinosaurs, providing a powerful visual testament to evolutionary connections. They then craft a C-E-R statement, eloquently articulating the compelling evidence for evolution presented by comparative anatomy.
This lesson not only imparts critical knowledge of comparative anatomy but also cultivates analytical thinking and scientific reasoning. It's an invaluable resource for educators seeking to inspire a profound understanding of evolution.

NGSS (Next Generation Science Standards)
High School NGSS Alignment
HS-LS4-1: Communicate scientific information that common ancestry and biological evolution are supported by multiple lines of empirical evidence.
Connection: Students use anatomical evidence—homologous, analogous, and vestigial structures—to explain how organisms share ancestry or have adapted differently.HS-LS4-2: Construct an explanation based on evidence that the process of evolution primarily results from genetic variation and natural selection.
Connection: Students connect differences in structure and function to adaptation over time.HS-LS4-3: Apply concepts of statistics and probability to support explanations that organisms with advantageous heritable traits tend to increase in proportion to organisms lacking those traits.
Connection: Students evaluate how structural similarities and differences influence survival across species.
Science & Engineering Practices:
Constructing explanations and designing solutions
Analyzing and interpreting data
Engaging in argument from evidence
Communicating scientific information
Crosscutting Concepts:
Structure and function
Patterns
Cause and effect
Common Core Standards
Grades 9–12:
CCSS.ELA-LITERACY.RST.9-10.1 / RST.11-12.1: Cite specific textual evidence to support analysis of scientific explanations. (Students use visual and text-based data to support claims about evolutionary evidence.)
CCSS.ELA-LITERACY.RST.9-10.7 / RST.11-12.7: Integrate quantitative or technical information expressed in words with visual data. (Students analyze comparative anatomy diagrams and data tables.)
CCSS.ELA-LITERACY.WHST.9-10.1 / WHST.11-12.1: Write arguments focused on discipline-specific content. (Students write a CER explaining how comparative anatomy supports evolution.)
CCSS.ELA-LITERACY.WHST.9-10.9 / WHST.11-12.9: Draw evidence from informational texts to support analysis and reflection. (Students integrate examples from readings and diagrams into their explanations.)
