New in @science.org ...since our first discoveries of early tetrapods, they have been thought of as "amphibians" characterized by aquatic larvae. But is this true? For the first time, we report exceptional fossils of stem tetrapod babies that upend this paradigm. 1/n www.science.org/doi/10.1126/...

👨🏻‍🔬 Stefano is an invited speaker in the "Evolution and Development of Digestive Systems: from Specialised Cell Types to Complex Ecosystems" symposium, where he will share their work on the shared AP molecular blueprint of adult guts, from worm to clownfish (doi.org/10.1371/jour...). #EED2026 [2/3]

Dissection of the gastrointestinal tract in the 5 species considered, and segment collection. From "Comparative transcriptomics reveal the common anteroposterior molecular blueprint of adult bilaterian guts" by Vianello et al. (2026), DOI: 10.1371/journal.pbio.3003571.

Adult guts in annelids, hemichordates, echinoderms, cephalochordates, and vertebrates. (A) Schematic phylogeny of the 5 bilaterian species compared in this study, and of their gastrointestinal anatomy. (B) For each species, heatmap of the Spearman’s Rank Correlation coefficients between all pairs of gut segments (white, low; purple, high). (C) For each species, distribution of gut segments (all replicates) across the two main Principal Components (PCs; PC1, PC2). (D) For each species, heatmap showing the expression pattern (z-scores) of the top 2000 most-variant genes along the gut (columns: AP-ordered gut segments). From "Comparative transcriptomics reveal the common anteroposterior molecular blueprint of adult bilaterian guts" by Vianello et al. (2026), DOI: 10.1371/journal.pbio.3003571.

Larval AP patterning genes display regionalized expression pattern along adult guts in bilaterian invertebrates. (A) Left: Left: qualitative “heatmap” showing the expression pattern (red, high; blue, low) of conserved gut patterning markers along the sea urchin larval gut; as per Annunziata and colleagues (2014). Right: heatmap showing the expression pattern (z-scores) of the same marker genes along the sea urchin adult gut AP axis (this study). (B) For each species, heatmap showing the expression pattern (z-scores) of all expressed gut patterning genes along the gut AP axis. From "Comparative transcriptomics reveal the common anteroposterior molecular blueprint of adult bilaterian guts" by Vianello et al. (2026), DOI: 10.1371/journal.pbio.3003571.

(A) Summary model of the conserved elements of the adult bilaterian through-gut, and their AP distribution, as identified in this work. Modules are color-coded. Slashed rectangle pictogram (blue, topmost): boundary between “block” and “gradient” compartments (i.e., “transition sphincter”) as defined in the main body of text. (B) Larval bilaterian through-guts. A correspondence between larval and adult AP gut markers (dark arrow) was identified for sea urchin (Sp). The AP patterning of adult bilaterian guts may in turn be a conserved feature of larval through-guts (light arrow). (C) Reconstruction (dark arrow) of the possible configuration of the ancestral through-gut configuration, which gave rise to the diversification of adult guts seen in extant species (light arrow to panel A). Our interpretative lens would further provide an investigative angle to approach the relationship between the ancestral through-gut configuration and that of its larva and the larvae of extant species (light arrows to and from panel B). A: anterior, P: posterior. From "Comparative transcriptomics reveal the common anteroposterior molecular blueprint of adult bilaterian guts" by Vianello et al. (2026), DOI: 10.1371/journal.pbio.3003571.
