Biological Classification Similarities in Living Things Drill 5/7 Read sections A – C of the “Making Cladograms – Background & Procedures”

Organisms are Classified by their Similarities and Differences Phylogeny is how groups of organisms are related to each other Homologous structures are alike in basic structure and origin (like flippers and wings) A cladogram or phylogenetic tree is a diagram that shows these relationships

Cladogram

Making a Cladogram We will be making a cladogram that shows how 7 different organisms are related to one another based on their characteristics
