Vessel tracking map for Globe40 regatta showing Cape Horn region.
Unrooted phylogenetic tree showing (Brachiopoda,Mollusca,(Annelida,(Platyhelminthes,Nemertea)))
15-unrooted topologies showing Spiralian relationships with coloured barplots for the proportion of bootstrap and jackknife replicates supporting each unrooted tree.
Boxplots showing median per topology log-likelihoods. Top two plots show sloping distribution with all Platyhelminth-rooted topologies with the 15 top-scored topologies. Bottom two plots show all values near y = 0.
Scatterplots showing branch lengths of interest. Platyhelminthes branch always above y-axis break and interphylum branches are the cluster of points closest to y = 0.
15 possible 5-taxon spiralian phylogenetic trees with list of publications supporting each tree
Word cloud visualization for 2025 showing your 50 most-used words, sized by frequency. Top 10: "support" (10×), "model" (8×), "deuterostome" (7×), "heterogeneity" (7×), "articles" (6×), "deuterostomia" (6×), "inference" (5×), "variation" (5×), "tree" (5×), "trees" (4×) (from Anisota's Annual Bluesky Harvest)
Phylogenetic tree showing Chordata (fish), Ambulacraria (acorn worm) and Protostomia (butterfly and snail) in a polytomy.
Boxplots showing difference in support between pairs of topologies binned by level of site-compositional constraints (number of effective amino acids). Deuterostomia (purple) always preferred to paraphyletic alternative but much less strongly under a site-heterogeneous model (EDM) and in teh absence of ong-branched taxa. Negligible difference in support between the two paraphyletic alternatives (Orthozoa-salmon and Centroneuralia-green).
Plot showing that number of sites supporting deuterostome monophyly (purple) decreases when long-branched taxa are excluded and when site-heterogeneous models are used.
Cladograms showing the three hypotheses of deuterostome relationships.
Scatter plot showing support for deuterostome relationships across phylogenomic studies published between 2008 and 2019. Red dots site-homogeneous substitution models, blue dots site-heterogeneous models.
