Three-tiered
approach
1st Tier:
Higher-Level Relationships*
Goal: Establish robust framework for deep relationships.
75 taxa sampled for morphology and ~23 kb of DNA sequence
data (complete mitochondrial genomes & several nuclear
genes).
2nd Tier:
Superfamily & Family Relationships
Goal: Establish relationships among superfamilies.
300 taxa sampled for morphology and ~11.8 kb of DNA sequence
data (nuclear & mitochondrial).
3rd Tier: Tribe & Subfamily Relationships
Goal: Establish relationships among tribes and subfamilies.
~3000 species sampled for ~1.5 kb of DNA sequence data,
and select taxa scored for morphology.
*Based on Lawrence
& Newton (1995).
