In centipedes, venom evolution is thought to be constrained by the morphological complexity of their venom glands due to physiological limitations on the number of toxins produced by their secretory cells. Here we show that the uneven toxin expression that results from these limitations have enabled <i>Scolopendra morsitans</i> to regulate the composition of their secreted venom despite the lack of gross morphologically complex venom glands. We show that this control is probably achieved by a combination of this heterogenous toxin distribution with a dual mechanism of venom secretion that involves neuromuscular innervation as well as stimulation via neurotransmitters. Our results suggest that behavioural control over venom composition may be an overlooked aspect of venom biology and provide an example of how exaptation can facilitate evolutionary innovation and novelty.</p>","PeriodicalId":18835,"journal":{"name":"Nature ecology & evolution","volume":"68 1","pages":""},"PeriodicalIF":16.8,"publicationDate":"2024-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142574565","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although a wealth of evidence supports this interpretation in birds, there has been no systematic attempt to identify modular organization in the bat limb skeleton. Here we present a phylogenetically representative and ecologically diverse collection of limb skeletal measurements from 111 extant bat species. We compare this dataset with a compendium of 149 bird species, known to exhibit modular evolution and anatomically regionalized skeletal adaptation. We demonstrate that, in contrast to birds, morphological diversification across crown bats is associated with strong trait integration both within and between the forelimb and hindlimb. Different regions of the bat limb skeleton adapt to accommodate variation in distinct ecological activities, with flight-style variety accommodated by adaptation of the distal wing, while the thumb and hindlimb play an important role facilitating adaptive responses to variation in roosting habits. We suggest that the wing membrane enforces evolutionary integration across the bat skeleton, highlighting that the evolution of the bat thumb is less correlated with the evolution of other limb bone proportions. We propose that strong limb integration inhibits bat adaptive responses, explaining their lower rates of phenotypic evolution and relatively homogeneous evolutionary dynamics in contrast to birds. Powered flight, enabled by the membranous wing, is therefore not only a key bat innovation but their defining inhibition.</p>","PeriodicalId":18835,"journal":{"name":"Nature ecology & evolution","volume":"6 1","pages":""},"PeriodicalIF":16.8,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142561896","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Carmignani et al. &lt;i&gt;Nature Ecology &amp; Evolution&lt;/i&gt; https://doi.org/10.1038/s41559-024-02548-9 (2024)&lt;/p&gt;&lt;p&gt;Carmignani and colleagues&lt;sup&gt;1&lt;/sup&gt; contend that our identification of the oldest and easternmost Initial Upper Palaeolithic (IUP) attribution at Shiyu, northern China&lt;sup&gt;2&lt;/sup&gt; is based on a misuse of technological definitions and biased artefact sampling. However, this criticism is hampered by restrictive Eurocentric definitions and methodological misunderstandings. Carmignani et al.&lt;sup&gt;1&lt;/sup&gt; apply a narrow definition of the Asian IUP based on the presence of points and blades reduced from sub-volumetric, non-Levallois-system burin cores. Shiyu does not perfectly conform to this definition, so they exclude its lithic industry from the IUP. We argue that this definition hampers understanding of modern human dispersals across Eurasia. Like any other discipline where classification is central, archaeologists define categories of objects and assemblages based on similarities in sets of traits. These categories are not inherently meaningful; rather, their significance arises from assumptions about underlying biological and cultural processes. The assumption that lends meaning to the IUP is that it reflects a combination of demic and cultural diffusion processes associated with the spread of &lt;i&gt;Homo sapiens&lt;/i&gt; throughout Eurasia&lt;sup&gt;3&lt;/sup&gt;. To understand this evolutionary history, we need to adopt a flexible comparative approach that uses the original IUP definition as a baseline rather than a set of strict, restrictive criteria. A more flexible approach may help to disentangle cultural innovations and diffusion occurring during or after demic diffusion, as well as cultural blending with local populations on a regional scale, thereby illuminating the complex interactions that certainly occurred, with possible implications for gene exchange. Success in this endeavour depends on being able to distinguish diffusion of innovation from cultural convergence. Opening up our definitions admittedly creates greater uncertainty about the drivers of similarity and the meaning that underlies cultural constructs&lt;sup&gt;4,5&lt;/sup&gt;, but there are good reasons for taking this risk. Can we reasonably believe that in a territory of 44 million km&lt;sup&gt;2&lt;/sup&gt;, stretching from the Arctic to the Equator, the expansion of &lt;i&gt;H. sapiens&lt;/i&gt; over thousands of years, encountering different hominin species, was associated with a single, uniform technology? It is clear in this context that the strict application by Carmignani et al.&lt;sup&gt;1&lt;/sup&gt; of a points, blades and volumetric burin core definition, possibly useful in characterizing the IUP in one region, will fail to capture the overall complexity of &lt;i&gt;H. sapiens&lt;/i&gt;’ expansion in others. This strict Eurocentric definition and interpretive framework does not pay attention to regional traditions in which cultural novelties occur, possibly signalling the dispersal of &lt;i&gt;H. sapiens&lt;","PeriodicalId":18835,"journal":{"name":"Nature ecology & evolution","volume":"97 1","pages":""},"PeriodicalIF":16.8,"publicationDate":"2024-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142519949","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, to resolve this, we have assembled multi-regional datasets, comprising bulk and compound-specific stable isotope values from zooarchaeological remains and pottery, and conducted cross-correlation analyses within a palaeo-environmental framework. Our findings reveal a diversity of pasturing strategies for cattle employed by early farmers, with a notable emphasis on intensive utilization of forests for grazing and seasonal foddering in some regions. This experimentation with forest-based animal feeds by early farmers would have enhanced animal fertility and milk yields for human consumption, concurrently contributing to the expansion of prehistoric farming settlements and the transformation of forest ecosystems.

It is therefore unclear why chimpanzees display a human-like pattern of pelvic sexual dimorphism despite having easier births enabled by small neonates and capacious pelvic canals. Here we reassessed chimpanzee fetopelvic fit using three-dimensional simulations, revealing a similarly constricted midpelvis as in humans, with even narrower outlet dimensions. Geometric morphometric analyses confirm that female chimpanzees have larger pelvic canals than males despite a smaller body size and a morphology that maximizes pelvic dimensions favourable for parturition, particularly in smaller-bodied individuals. Together with evidence for increased neurological immaturity at birth relative to monkeys, our findings imply substantial obstetric constraints in chimpanzees and possibly other apes. We therefore propose that difficult birth did not arise abruptly in <i>Homo</i> with increasing encephalization but evolved gradually through a series of obstetric compromises from an already constricted birth canal shared across anthropoid primates. Specifically, we propose that obstetric selection pressures exacerbated incrementally with the stiffening of the symphysis that accompanied body size increase in hominoids, while subsequent adaptations to bipedalism shortened the ilium.
