“…This anatomical region is under strong genetic control, as it is established early during ontogeny through fast endochondral ossification from cartilaginous structure (Smith, 2009;Smith et al, 2007). It has been hypothesized that this feature ensured a better degree of stabilization because it is less affected by external variables than other parts of the cranium (e.g., the maxillofacial regions) and often recognized as useful to explore past microevolutionary processes (Bader et al, 2022;Harvati & Weaver, 2006;Plomp et al, 2021;Smith, 2009Smith, , 2011Smith et al, 2007Smith et al, , 2013Timbrell & Plomp, 2019). Those that ossify endochondrally (like the temporal bone) are more highly correlated with molecular distances than regions that ossify intramembranously.…”

“…This bioarchaeological study is the first to explore Quebec's phenotypical population history over three centuries (17th–19th c. AD). Ancient DNA studies are often preferred but remain a costly and destructive tool that suggests caution, especially when archeological human remains are badly preserved (Bader et al, 2022). The present article is part of a series of ongoing research and focuses on investigating intraregional and interregional temporal bone variation in colonial Québécois populations to explore European and non‐European biological diversity (Martin‐Moya & Ribot, in revision).…”

ObjectivesIn Quebec, genetic and genealogical research are used to document migratory events and family structures since colonial times, because bioarchaeological analysis is limited by poor skeletal preservation. This article aims to fill this gap by exploring past population structure in the St‐Lawrence Valley from the French (1683–1760) and British (1760–1867) regimes using morphological variation of well‐preserved temporal bones.Materials and Methods3D geometric morphometrics shape data from seven populations (five Catholics of French descent and two Protestants of British descent; n = 214) were collected from temporal bones. Using Procrustes distances and both MANOVA and Discriminant Function Analysis, morphological differences were measured to calculate affinities patterns among populations. Shape variations were explored with between‐group analysis, Mahalanobis distances and quantified by means of Fst estimates using Relethford–Blangero analysis.ResultsDespite strong affinities between all Catholic cemeteries, all show divergent morphological regional diversity ‐especially Montreal and the fortified villages dedicated to its defense. Montreal exhibits low increase in morphological variance over three centuries. As our results show no morphological differences between the Catholic and the Protestant cemeteries in Montreal, this fact may highlight the potential presence of Irish or admixed individuals in Montreal cemeteries after the British takeover.DiscussionPatterns of morphological diversity highlighted that French colonists did not equally contribute to the descendant populations as reflected by significant interregional variation. Although historical records show that French and English‐speaking populations did not tend to admix, morphological affinities between Protestants and Catholics in the beginning of the industrial era in Montreal could reflect the genetic contribution of Catholic Irish migrants.Research Highlights All Catholic cemeteries display distinct morphologies, highlighting differential contributions from French colonists and founder effects, which have increased regional differences. Montreal Catholic (French descent) and Protestant (English colonists) cemeteries show significant morphological affinities at the beginning of the industrial era. The Irish migration following the British conquest may explain morphological similarities observed between Catholic and Protestant cemeteries.

Aquatic birds represent diverse ecologies and locomotion types. Some became flightless or lost the ability for effective terrestrial locomotion, yet, certain species excel in water, on land, and in air, despite differing physical characteristics associated with each medium. In this exploratory study, we intend to quantitatively analyze the morphological variety of multiple limb bones of aquatic birds using 3D geometric morphometrics. Morphological variation is mainly driven by phylogeny, which also affects size and locomotion. However, the shape of the ulna, including the proportion and orientation of the epiphyses is influenced by size and aquatic propulsive techniques even when phylogeny is taken into consideration. Certain trends, possibly linked to functions, can be observed too in other bones, notably in cases where phylogenetic and functional signals are probably mixed when some taxa only englobe species with similar functional requirements: penguins exhibit the most distinctive wing bone morphologies, highly adapted to wing‐propulsion; advanced foot‐propellers exhibit femur morphology that reduces proximal mobility but supports stability; knee structures, like cnemial crests of varied sizes and orientations, are crucial for muscle attachments and efficient movement in water and on land; taxa relying on their feet in water but retaining terrestrial abilities share features enabling swimming and walking postures. Size‐linked changes distinguish the wing bones of non‐wing‐propelled taxa. For hindlimbs, larger size relates to robust bones probably linked to terrestrial abilities, but robustness in femora can be connected to foot‐propulsion. These results help us better understand birds' skeletal adaptation and can be useful inferring extinct species' ecology.
