Riedl served as a motivator for many researchers that later took up questions related to evolvability, and also had an indirect influence in that Riedl-inspired researchers created a research program to combine the systems thinking that Riedl championed with the theoretical population genetics of the modern synthesis. Notably, this was despite a near-total absence of population perspectives in Riedl's personal research. In this essay I review some of Riedl's perspectives on evolvability, speculate on his influence on later evolvability research, and review what we have later learned about the questions and perspectives initiated by him.</p>","PeriodicalId":15682,"journal":{"name":"Journal of experimental zoology.

In most insect models, this transition occurs through synchronous cellularization, producing a uniform blastoderm that is patterned only afterward. Whether this sequence represents a common developmental principle across insects remains unclear. Here, we show that in the carpenter ant <i>Camponotus floridanus</i>, cellularization proceeds progressively rather than synchronously and establishes spatially differentiated blastoderm domains. Cellularization initiates at the anterior and progresses posteriorly, while a second front from the posterior advances in the opposite direction. These opposing fronts converge at the site where the germline capsule subsequently forms. At the same time, a regionalized blastoderm rather than a uniform blastoderm is established. The extraembryonic tissues amnion, serosa, and trophocytes emerge along progressive cellularization through coordinated morphogenetic dynamics and exhibit a distinct mode of organization. Our data present a revised understanding of cellularization of blastoderm in insects and broaden the comparative framework of embryogenesis described in model organisms.</p>","PeriodicalId":15682,"journal":{"name":"Journal of experimental zoology.

Diving beetles (Dytiscidae) are predaceous freshwater insects with strictly aquatic larvae and amphibious adults. Using RNA-seq, we compared the expression of odorant receptors (ORs), gustatory receptors (GRs), ionotropic receptors (IRs), and odorant-binding proteins (OBPs) in the cephalic appendages of larval and adult <i>Cybister lateralimarginalis</i>. Overall, larvae expressed fewer chemosensory genes than adults but larva-specific genes displayed a unique expression pattern, not previously observed in any other holometabolous insect, with five larva-specific ORs all having a close paralogue which is adult-specific, 14 larva-specific IRs all belonging to a single gene expansion in the IR tree, and no larva-specific GR. Expression profiles across appendage types mirrored those in aerial insects, with ORs mainly in antennae, GRs in labial palps, “Antennal class” IRs in antennae, and “Divergent class” IRs in palps. This suggests that the land-to-freshwater transition in this lineage did not involve major changes in deployment of the major families of chemosensory genes among cephalic appendages. Notably, the expression of a substantial repertoire of ORs specifically in the antennae of the larva suggests that hydrophobic chemical cues are important for long-range chemodetection in freshwater, contrary to prevailing views about constraints for chemosensation within a water medium.</p></div>","PeriodicalId":15682,"journal":{"name":"Journal of experimental zoology.
