What provides the basis for clarification (systematics), as well as a framework for understanding evolutionary characteristics?
Phylogenies
How are phylogenies created?
- ……
- ……
How are phylogenies created?
- Data- Observe, record, and compare characteristics (Morphology, molecular sequences)
-
Phylogenetic Tree- Analyze the data to develop a branching diagram
- Depends on how large data set is
