Abstract Aim The ‘rate‐of‐living’ theory predicts that life expectancy is a negative function of the rates at which organisms metabolize. According to this theory, factors accelerate metabolic rates, such as high body temperature and active foraging, lead organismic ‘wear‐out’. This process reduces span through an accumulation biochemical errors build‐up toxic by‐products. Although rate‐of‐living keystone underlying our understanding life‐history trade‐offs, its validity has been recently questioned. never tested on global scale in phylogenetic framework, or across both endotherms ectotherms. Here, we test several fundamental predictions tetrapod tree life. Location Global. Time period Present. Major taxa studied Land vertebrates. Methods Using dataset spanning data 4,100 land vertebrate species (2,214 endotherms, 1,886 ectotherms), performed most comprehensive date theory.

As a result of the process descent with modification, closely related species tend to be similar one another in myriad different ways. In statistical terms, this means that traits measured on will not independent others. Since their introduction 1980s, phylogenetic comparative methods (PCMs) have been framed as solution problem. article, we argue way thinking about PCMs is deeply misleading. Not only has sowed widespread confusion literature what are doing but led us develop susceptible very thing sought build defenses against—unreplicated evolutionary events. Through three Case Studies, demonstrate susceptibility singular events indeed recurring problem biology links several seemingly unrelated controversies. each Study, propose potential While details our proposed solutions differ, they share common theme: unifying hypothesis testing data-driven approaches (which term "phylogenetic natural history") disentangle impact from factors investigating. More broadly, field has, at times, sloppy when weighing evidence support causal hypotheses. We suggest refine inferences re-imagine phylogenies probabilistic graphical models; adopting help clarify precisely and supports claims.

Ornaments used in courtship often vary wildly among species, reflecting the evolutionary interplay between mate preference functions and constraints imposed by natural selection. Consequently, understanding dynamics responsible for ornament diversification has been a longstanding challenge biology. However, comparing radically different ornaments across as well classes of within is profound to sexual signals.

ABSTRACT Despite many decades of research, the allometric scaling metabolic rates (MRs) remains poorly understood. Here, we argue that exponents these allometries do not themselves mirror one universal law nature but instead statistically approximate non‐linearity relationship between MR and body mass. This ‘statistical’ view must be replaced with life‐history perspective ‘allows’ organisms to evolve myriad different life strategies distinct physiological features. We posit hypoallometric allometry MRs (mass an exponent smaller than 1) is indirect outcome selective pressure ecological mortality on allocation ‘decisions’ divide resources among growth, reproduction, basic costs repair maintenance reflected in standard or basal rate (SMR BMR), which are customarily subjected analyses.

Glucocorticoid (GC) hormones are important phenotypic mediators across vertebrates, but their circulating concentrations can vary markedly. Here we investigate macroevolutionary patterning in GC levels tetrapods by testing seven specific hypotheses about variation and evaluating whether the supported reveal consistent patterns evolution. If selection generally favors "supportive" role of GCs responding effectively to challenges, then baseline and/or stress-induced may be higher challenging contexts. Alternatively, if "protection" from GC-induced costs, lower environments where challenges more common or severe. The predictors were all with supportive effects: smaller organisms those inhabiting energetically demanding environments. During breeding, also populations species fewer lifetime opportunities reproduce. instead protection hypothesis: during reproductive opportunities. Overall, these indicate a surprising degree consistency how some selective pressures shape broad taxonomic scales; at same time, appears operate on distinct ways.

Behavior is one of the major architects evolution: by behaviorally modifying how they interact with their environments, organisms can influence natural selection, amplifying it in some cases and dampening others. In earliest issues Evolution, Charles Bogert proposed that regulatory behaviors (namely thermoregulation) shield from selection limit physiological evolution. Here, I trace history surrounding origin this concept (now known as "Bogert effect" or "behavioral inertia"), its implications for evolutionary research throughout 20th century. A key follow-up study early 21st century galvanized renewed interest Bogert's classic ideas, established a focus on slowdowns rate evolution response to behaviors. illustrate recent progress effect research, discuss ecological variables predict whether strongly phenomenon unfolds. Based these discoveries, provide hypotheses across several scales: patterns trait within among groups species, spatial effects phenomenon, importance speciation. also inherent link between behavioral inertia drive through an empirical case linking phenomena. Modern comparative approaches help put macroevolutionary buffering test: describe date, areas ripe future investigation. Despite many advances, bridging microevolutionary processes remains persistent gap our understanding effect, leaving wide open avenues deeper exploration.
