- An organism's features reflect its evolutionary history.
- Scientists test their ideas using multiple lines of evidence. (P6, NOS2)
- Scientists use the similarity of DNA nucleotide sequences to infer the relatedness of taxa. (LS4.A)
- Evolutionary trees (i.e., phylogenies or cladograms) are built from multiple lines of evidence.
- As with other scientific disciplines, evolutionary biology has applications that factor into everyday life.
- Evolutionary trees (i.e., phylogenies or cladograms) portray hypotheses about evolutionary relationships.
