Different relationship between Gomphidae, Petaluridae, and Cavilabiata recovered based on the rate of evolution of genes
Rate of gene evolution decreases from left to right. On the extreme left is the relationship recovered using a subset of fastest 50% of the genes while on the extreme right is the relationship recovered from a subset of slowest 25% of the genes. Numbers on the nodes represent the quartet support for the branch leading upto the nodes recovered in an MSC analysis.
