What is this and what does it show?

What is cladistics?Objectives

Know what a clade is and the evidence that makes an organism part of a clade.

Interpret cladograms.

Outcomes

3: Outline key principles and evidence for cladistics.

5: Successfully complete all aspects of the lab to explore

cladistics.

7: Evaluate the issues with grouping organisms and how new discoveries can shift our

view point in biology.

What is cladistics?

Key terms: cladistics, clade, DNA, molecular, analogous, homologous

Homologous structures have similar ancestry

Analogous structures are similar because of convergent evolution i.e they show similarities in structure and function but evolved

independently.
