Then add in when the different traits most likely evolved. TIGER HUMANS FROGS CATFISH HAIR SLUGS LEGS BACKBONE CELLSĭ. TIGER HUMANS FROGS CATFISH SLUGS LEGS BACKBONE CELLSĭ. TIGER HUMANS FROGS CATFISH SLUGS BACKBONE CELLSĭ. Less evolved organisms go at the bottom or left side of the cladogram. It is assumed that organisms with more of the traits evolved later, so they go at the top or on the right. Less evolved organisms go at the bottom or left side of the cladogram.Ĭ. Cells: Slug, Catfish, Frog, Tiger and Human Backbone: Catfish, Frog, Tiger and Human Legs: Frog, Tiger and Human Hair: Tiger and Human Thumbs: HumanĬ. Then create a Venn diagram, placing the animals in groups to illustrate those characteristics which different animals have in common. Cells: Slug, Catfish, Frog, Tiger and Human Backbone: Catfish, Frog, Tiger and Human Legs: Frog, Tiger and Human Hair: Tiger and Humanī. Cells: Slug, Catfish, Frog, Tiger and Human Backbone: Catfish, Frog, Tiger and Human Legs: Frog, Tiger and Humanī. Cells: Slug, Catfish, Frog, Tiger and Human Backbone: Catfish, Frog, Tiger and Humanī. Cells: Slug, Catfish, Frog, Tiger and Humanī. For example: Cells Backbone Legs Hair Thumbs Slug X Catfish Frog Tiger Humanī. Make a table of some adaptations that the organisms share, and some that are unique. Let’s make a cladogram that includes slugs, catfish, frogs, tigers, and humans. For example: Cells Backbone Legs Hair Thumbs Slug Catfish Frog Tiger Human Everything past this point has four walking legs! Sometimes a cladogram will list the characteristics that make two groups or organisms different (traits). This means they evolved apart more recently. The closer two species are on the cladogram, the more closely they are related. Presentation on theme: "Cladograms."- Presentation transcript:Ī cladogram shows evolutionary relationships between groups of living things.
