Avian evolution led to morphological adaptive variations in feet. Diverse foot types are accompanied by a diverse muscle system, allowing birds adopt different primary lifestyles, and display various locomotor manipulative skills. We provide insights of evolutionary functional significance on the avian architecture through Anatomical Network Analysis, methodology focused connectivity patterns anatomical parts. Here, we show that: (1) parts largely conserved living already present ancestral dinosaurs exhibit highest degree, (2) there is no link between more complex networks ability perform specialized skills or higher number tasks, (3) trend towards simplification macroevolutionary scale within birds, (4) phylogenetically constrained all despite their type diversity, probably due stabilizing selection. Birds have evolved large diversity morphologies past 100 million years. authors use network analysis find organization, toward simplification, association complexity specialization.

Parrots (Order: Psittaciformes) are a diverse clade that is easily distinguishable from other birds. Despite the clear characters define Psittaciformes (hooked bills, zygodactylous feet, and plumage often predominantly green or red), relative morphological uniformity among parrots has made taxonomic classification fraught endeavor for over century. Parrot systematics were propelled forward when DNA sequencing data shed insights into higher- species-level relationships. However, despite these significant advances, major gaps in taxon sampling uncertainty relationships remained due to inferring phylogenetic with short fragments of DNA. Recent work using genome-wide molecular markers nearly complete parrot brought clarity many remaining outstanding questions on Here, we build this by including four additional species present revision better aligned its evolutionary tree. We infer maximum likelihood time-calibrated phylogenies parrots, accounts 106 genera, compare how our findings relate previous work, highlight future areas research.

Abstract Pinnipeds (seals, sea lions, walruses, and their fossil relatives) are one of the most successful mammalian clades to live in oceans. Despite a well-resolved molecular phylogeny global record, complete understanding macroevolutionary dynamics remains hampered by lack formal analyses that combine these 2 rich sources information. We used meta-analytic approach infer densely sampled pinniped date (36 recent 93 taxa) phylogenetic paleobiological methods study diversification biogeographic history. mostly diversified at constant rates. Walruses, however, experienced rapid turnover which extinction rates ultimately exceeded speciation from 12 6 Ma, possibly due changing levels and/or competition with otariids (eared seals). Historical analyses, including data, allowed us confidently identify North Pacific Atlantic (plus or minus Paratethys) as ancestral ranges Otarioidea seals + walrus) crown phocids (earless seals), respectively. Yet, despite novel addition stem pan-pinniped taxa, region origin for Pan-Pinnipedia remained ambiguous. These results suggest further avenues pinnipeds provide framework investigating other groups substantial extinct extant diversity.

Functional diversity is increasingly used alongside taxonomic to describe populations and communities in ecology. Indeed, functional metrics allow researchers summarise complex occupancy patterns space and/or time across response various stressors.

However, as the methods increases, it often not directly clear which metric more readily appropriate for question. We studied ability different recover signals from processes linked common assembly mechanisms community ecology, such environmental filtering, competitive exclusion, equalising fitness, facilitation. Using both simulated data empirical dataset affected nuanced mechanisms, we tested effectiveness or changes. show that perform differently when trying capture approximations relative no mechanism all (null). For example, competition was harder disentangle null compared facilitation our simulations. This emphasises importance using one‐size‐fits‐all metric.

Widely documented, megaevolutionary jumps in phenotypic diversity continue to perplex researchers because it remains unclear whether these marked changes can emerge from microevolutionary processes. Here, we tackle this question using new approaches for modeling multivariate traits evaluate the magnitude and distribution of elaboration innovation evolution bird beaks. We find that elaboration, along major axis change, is common at both macro- scales, whereas innovation, away more prominent scales. The change among species beak shapes scales an emergent property across clades. Our analyses suggest reorientation phenotypes via a ubiquitous route divergence arise through gradual alone, opening up further avenues explore.

Abstract Attempts to predict macroevolution from microevolution, and microevolution macroevolution, when natural selection is the main cause have met with varying success. Explanations for failure are numerous, but reasons uncertain even a link found. Here, I discuss possible explanations outcomes of three efforts ways test them. First, quantitative genetic variation within populations often predicts directions species divergence surprising accuracy. Natural probably contributes this pattern, evidence suggests that long-term phenotypic evolution influenced by enduring biases. Second, rate reproductive isolation repeatedly fails diversification rates unknown reasons. Suspicion falls on influence ecological population demographic processes might play dominant role in net accumulation species, an idea as yet little tested. Third, macroevolutionary patterns distribution phenotypes clades can principle coefficients diverging populations. use concept adaptive landscape suggest why signal divergent strongest at time splitting information about phylogenetic methods remains long run.

Animal phenotypes evolve and diverge as a result of differing selective pressures drift. These processes leave unique signatures in patterns trait evolution, impacting the tempo mode morphological macroevolution. While there is broad understanding history some organismal traits (e.g., body size), little consensus about evolutionary most others. This includes relative contribution prolonged (Darwinian gradualist) episodic (Simpsonian jump) changes toward evolution novel morphologies. Here, we use new exon-capture linear datasets to investigate Australo-Melanesian Tiliquini skinks. We generate well-supported time-calibrated phylogenomic tree from ∼400 nuclear markers for more than 100 specimens, including undescribed diversity, provide unprecedented resolution rapid Miocene diversification these lizards. By collecting dataset that encompasses lizard plan (19 across head, body, limb, tail), are able identify conservatively, but infrequent bursts novelty. phenotypic discontinuities occur via rate increases along individual branches, inconsistent with both gradualistic punctuated equilibrial modes. Instead, this "punctuated gradualism" has resulted blue-tongued giants armored dwarves ∼20 million years since colonizing Australia. results outline pathway morphologies highlight heterogeneity mode, even within traits.

Historically, this debate centers inconsistencies microevolutionary processes macroevolutionary patterns. Here, we characterize striking exception: emerging evidence indicates that standing variation rates phenotypic divergence is often positively correlated. This apparent consistency micro- macroevolution paradoxical because it contradicts our previous understanding so far unexplained. explore prospects for bridging through an examination “paradox predictability.” We begin by explaining why divergence–variance correlation paradox, followed data analysis to show general phenomenon across broad range temporal scales, from few generations tens years.
