Phylogenomic analysis of ultraconserved elements clarifies relationships and morphological evolution in Cryptoplacoidea (Mollusca: Polyplacophora)

Cladistics, EarlyView.
Abstract Targeted enrichment of ultraconserved elements (UCEs) is a powerful tool for resolving phylogeny in groups with limited morphological or molecular data. Here, we use UCEs to reconstruct the first comprehensive phylogeny of the chiton superfamily Cryptoplacoidea, including museum material up to 133 years old.
