Neighbor joining dendrogram of the Xenotilapia lineage based on Nei & Li's genetics distance calculated from 2,478 AFLP loci.
Numbers at each node indicate bootstrap values (from 10,000 replicates) for that node. Lines on the right indicate current generic assignment of each taxon. The tree was rooted with Opthalmotilapia nasuta and O. ventralis.

Convergent evolution of mating strategies within the Ectodini/Xenotilapia clade from Lake Tanganyika.
Ancestral character state reconstruction by maximum parsimony revealed multiple transitions from biparental (red) to maternal only care (blue), which would require the repeated evolution neural and endocrine pathways regulating parental care and mate choice decisions. Our analysis was unable to resolve the parental care state for the ancestor of the clade consisting of X. ornatipinnis, X. spiloptera and X. sp. “papilio sunflower” (barred).
