Towards a Thoroughly Kripkean Theory of Proper Name Reference

open access: yesTheoria, EarlyView.
ABSTRACT In the late 1960s and early 1970s, both Saul Kripke and Keith Donnellan challenged descriptivist theories of proper names, arguing that reference—at least in their case—is basically a historical relation. However, as has become increasingly recognised over the past decade, their pictures differ substantially: when confronted with a token of a ...

The flexible, the stereotyped and the in‐between: putting together the combinatory tool use origins hypothesis

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1235-1254, June 2026.
ABSTRACT Tool use research has long made the distinction between tool using that is considered learned and flexible, and that which appears to be instinctive and stereotyped. However, animals with an inherited tool use specialisation can exhibit flexibility, while tool use that is spontaneously innovated can be limited in its expression and facilitated

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1406-1462, June 2026.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

Helmeted hornbill cranial kinesis: Balancing mobility and stability in a high‐impact joint

open access: yesThe Anatomical Record, Volume 309, Issue 5, Page 1299-1312, May 2026.
Abstract Prokinesis—in which a craniofacial joint allows the rostrum to move relative to the braincase—is thought to confer diverse advantages in birds, mostly for feeding. A craniofacial joint would, however, be a weak link if cranial stability is important. Paradoxically, we have identified a craniofacial joint in helmeted hornbills (Rhinoplax vigil),
