Pancrustacean topology shifts with taxon sampling

Two closely related genomic datasets isolate how modest taxon changes can reorganize deep pancrustacean relationships.

Represented range0–0 Ma

RegionsNinety transcriptomes and fifteen genomes across Pancrustacea

Using identical ortholog-selection methods, 98- and 105-taxon pancrustacean matrices yield materially different deep topologies; 90 transcriptomes, 15 genomes and 576 protein-coding genes therefore demonstrate sampling sensitivity rather than a final universal crustacean tree.
