Presentation Transcript

  1. Warm up 6/6 • Make a Venn Diagram Comparing and Contrasting Protists and Fungi • 4 similarities and 4 differences minimum Cladistics and Cladograms pp. 341-345

  2. Cladistics is classification based on common ancestry. • Phylogeny is the evolutionary history for a species. • evidence from living species, fossil record, and molecular data • shown with branching tree diagrams

  3. based on common ancestry • species placed in order they descended from common ancestor • Cladistics is a common method to make evolutionary trees.

  4. A cladogram is an evolutionary tree made using cladistics. • A clade is a group of species that shares a common ancestor. • Each species shares some traits with the ancestor. • Each species has traits that have changed.

  5. 1 Tetrapoda clade 2 Amniota clade 3 Reptilia clade 4 Diapsida clade 5 Archosauria clade FEATHERS & TOOTHLESS BEAKS. SKULL OPENINGS IN FRONT OF THE EYE & IN THE JAW OPENING IN THE SIDE OF THE SKULL SKULL OPENINGS BEHIND THE EYE EMBRYO PROTECTED BY AMNIOTIC FLUID FOUR LIMBS WITH DIGITS DERIVED CHARACTER • Derived characters are traits shared in different degrees by clade members. • basis of arranging species in cladogram • more closely related species share more derived characters • represented on cladogram as hash marks

  6. CLADE 1 Tetrapoda clade 2 Amniota clade 3 Reptilia clade 4 Diapsida clade 5 Archosauria clade NODE FOUR LIMBS WITH DIGITS DERIVED CHARACTER • Nodes represent the most recent common ancestor. • Clades can be identified by snipping a branch under a node. FEATHERS AND TOOTHLESS BEAKS. SKULL OPENINGS IN FRONT OF THE EYE AND IN THE JAW OPENING IN THE SIDE OF THE SKULL SKULL OPENINGS BEHIND THE EYE EMBRYO PROTECTED BY AMNIOTIC FLUID
