Cladogram / Phylogenetic Tree

Punctuated Equilibrium Theory in evolution that proposes that most species will show little evolutionary change in their history Most of the time, organisms are very stable Rapid changes Proposed by Stephen Jay Gould

How are cladograms constructed? Organisms are grouped together based on their shared characteristics (trait modified from the ancestral trait).

Cladograms are used to… Organize organisms based on evolutionary relationships (Phylogeny) In other words, who is related to whom and where did we they come from?

Cladogram Practice Using the Table, create a cladogram

Independent Practice To make a cladogram, first look at the animals you are studying and establish characteristics that they share and ones that are unique. Using the table, indicate whether the characteristic is present or not. Based on the table, create a cladogram Cells Backbone Legs Hair Opposable Thumbs Slugs Catfish Frog Tiger Human
