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

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

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

6. Nodes represent the most recent common ancestor.
FOUR LIMBS WITH DIGITS
Nodes represent the most recent common ancestor.
CLADE
Tetrapoda clade 1
Amniota clade 2
Reptilia clade 3
Diapsida clade 4
Archosauria clade 5
Clades can be identified by snipping a branch under a node.
FEATHERS AND TOOTHLESS BEAKS.
