Phylodynamic models can be used to estimate diversification trajectories from time-calibrated phylogenies.

The effect of traits on diversification rates is a major topic study in the fields evolutionary biology and palaeontology. Many researchers investigating these macroevolutionary questions currently make use extensive suite state-dependent speciation extinction (SSE) models. These models were developed for, are almost exclusively used with, phylogenetic trees extant species. However, analyses considering only taxa limited their power to estimate rates. Furthermore, SSE can erroneously detect associations between neutral when true associated trait not observed. In this study, we examined impact including fossil data accuracy parameter estimates under binary-state (BiSSE) model. This was achieved by combining with fossilized birth–death process. We show that inclusion fossils improves extinction-rate for applying BiSSE model Bayesian inference framework, no negative speciation-rate state transition-rate compared from taxa. even addition data, continued incorrectly identify correlations traits. article part theme issue ‘“A mathematical theory evolution”: dating back 100 years’.

Phylogenetic models are commonly used in palaeobiology to study the patterns and processes of organismal evolution. In human sciences, phylogenetic methods have been deployed for reconstructing ancestor-descendant relationships using linguistic material culture data. Within evolutionary archaeology specifically, analyses based on maximum parsimony discrete traits dominate, which sets limitations downstream role cultural phylogenies, once derived, can play more elaborate analytical pipelines. Recent methodological advances Bayesian phylogenetics, however, now allow us infer dynamics continuous characters. Capitalizing these developments, we here present an exploratory analysis macroevolution projectile point shape evolution European Final Palaeolithic earliest Mesolithic (approx. 15 000-11 000 BP) a phylodynamic approach fossilized birth-death process model.

Much of our view on Mesozoic dinosaur diversity is obscured by biases in the fossil record. In particular, spatiotemporal sampling heterogeneity affects identification timing and geographical location radiations, recognition latitudinal gradient, as well interpretation purported extinctions, faunal turnovers their drivers, including Early Jurassic Jenkyns Event across Jurassic/Cretaceous boundary. The current distribution means it impossible to robustly determine whether these 'events' were globally synchronous geologically instantaneous or spatiotemporally staggered. Accounting for also paramount reconciling notable differences results based sampling-standardized species richness versus reconstructions diversification rates, particularly with regards lead-up Cretaceous/Paleogene mass extinction. Incorporation a greater proportion stratigraphically well-resolved dinosaurs into analyses imperative must include substantial radiation birds. Given relative rarity temporally successive, well-sampled spatial windows, remains possible that rate showed little change after clade's initial until However, better understanding underlying sampling, combined holistic approach reconstructing diversification, an important step testing this hypothesis.
