Essential Question: How do species change over time to survive in different environmental conditions?
Concept 4: Evidence of Evolution
Objectives:
Explain what phylogenetic trees represent and what we use them for.
Diagram that biologists use use to predict the evolutionary relationships of organisms
Classifies organisms into major taxa based in evolutionary relationships.
Classifies species in the order in which they descended from a common ancestor using physical characteristics.
Trees can show order of species divergence from the common ancestor and some even more specifically show time of divergence.
List the levels of classification recognized by modern taxonomists and how they relate to phylogenetic trees.

2 word naming system made by Carolus Linnaeus.
Interpret a phylogenetic tree in order to make statements about relationships between organisms.
The bear and the chimpanzee are the most related with the most common recent ancestor between the two being the common mammal ancestor.
The least related species are the Lamprey and chimpanzee/bear.
The most recent common ancestor between the lamprey and the chimpanzee is the common vertebrate ancestor.
The most recent common ancestor between the sunfish and lamprey is the common vertebrate ancestor.
The most recent common ancestor between the sunfish and the Newt is the common jawed vertebrate ancestor.
The most recent common ancestor for the Newt and lizard is the Common Tetrapod ancestor.
The most recent ancestor between the bear and lizard is the common amniote ancestor.
