Farrell analyzed highly conserved DNA sequences from 115 species of the herbivorous beetle
subfamilies, sampling up to six species from each, to create a phylogenetic tree showing the
likely evolutionary relationships of today's beetles and when they diverged from common ancestors.
Although all seven genes in the interval are Idd10 candidates, we suggest the gene encoding the EWI immunoglobulin
subfamily member EWI - 101 (Cd101) as the most
likely Idd10 candidate because of the previously reported immune - associated properties of the human CD101 molecule.
