Inter-specifically, mammalian species with larger brains built of numerous neurons have higher cognitive abilities (CA) but at the expense metabolic costs. It is unclear, however, how this pattern emerged since evolutionary mechanisms act intra-specifically, not inter-specifically. Here, we tested existence above level in hippocampus—the brain structure underlying CA. We used an artificial selection experiment consisting lines laboratory mice divergently selected for basal rate (BMR)—a trait implicated size evolution, its costs and Selection on BMR did affect hippocampus as a correlated response to selection. However, high had superior CA manifested increased neuronal density, cytochrome c oxidase density (indexing activity) dendritic spine connectivity between neurons). Thus, our study calls into question generality patterns evolution apparent interspecifically. At level, may arise through rearrangement architecture function without conspicuous increase their metabolism.

The global rise of antibiotic resistance in bacterial pathogens and the waning efficacy antibiotics urge consideration alternative antimicrobial strategies. Phage therapy is a classic approach where bacteriophages (bacteria-specific viruses) are used against infections, with many recent successes personalized medicine treatment intractable infections. However, perpetual challenge for developing generalized phage expectation that viruses will exert selection target bacteria to deploy defenses virus attack, causing evolution during patient treatment. Here we review two main complementary strategies mitigating therapy: minimizing ability populations evolve driving (steering) phage-resistant toward clinically favorable outcomes. We discuss future research directions might further address phage-resistance problem, foster widespread development deployment therapeutic outsmart evolved clinical settings.

Evolutionary biology provides a crucial foundation for medicine and behavioral science that has been missing from psychiatry. Its absence helps to explain slow progress; its advent promises major advances. Instead of offering new kind treatment, evolutionary psychiatry scientific useful all kinds treatment.

Polyploidy, resulting from whole‐genome duplication (WGD), is ubiquitous in nature and reportedly associated with extreme environments biological invasions. However, WGD usually comes great costs, raising questions about the establishment chance of newly formed polyploids. The surprisingly high number polyploid mixed‐ploidy species observed may be a consequence their continuous emergence or reflect stable persistence even coexistence ancestral ploidy under certain circumstances. empirical studies on contemporary often neglect cost–benefit balances characteristics, tradeoffs between phenotypic intercytotype interactions, recurrent formation, stochastic processes. Here, we advocate for considering population‐level success, combining aforementioned factors that affect long‐term ancestors. We approach paradox despite costs modern theory perspective give an overview diversity mechanisms timing potentially enable rather than transient persistence.

Major changes in genetic variation are generally considered deleterious to populations. The massive biodiversity of insects distinguishes them from other animal groups. Insect deviant effective population sizes, alternative modes reproduction, advantageous inbreeding, endosymbionts, and factors translate highly specific inbreeding outbreeding outcomes.

How traits at multiple levels of biological organization evolve in a correlated fashion response to directional selection is poorly understood, but two popular models are the very general "behavior evolves first" (BEF) hypothesis and more specific "morphology-performance-behavior-fitness" (MPBF) paradigm. Both acknowledge that often acts relatively directly on behavior when evolves, other will as well most with some lag. However, this proposition exceedingly difficult test nature. Therefore, we studied responses high-runner (HR) mouse experiment, which four replicate lines have been bred for voluntary wheel-running compared nonselected control (C) lines. We analyzed wide range measured generations 20–24 (with focus new data from generation 22), coinciding point all HR were reaching limits (plateaus). Significance (226 P values) across trait types by ANOVA, used positive false discovery rate comparisons. This meta-analysis showed that, surprisingly, measures performance (including maximal oxygen consumption during forced exercise) no evidence having diverged between C lines, nor did any life history (e.g., litter size), whereas body mass had responded (decreased) least strongly wheel running. Overall, results suggest mice evolved primarily changes motivation rather than ability time they limits. In addition, neither BEF model MPBF hierarchical evolution provides particularly good fit experiment.

Microbes are evolutionarily robust organisms capable of rapid adaptation to complex stress, which enables them colonize harsh environments. In nature, microbes regularly challenged by starvation, is a particularly stress because resource limitation often co-occurs with changes in pH, osmolarity, and toxin accumulation created metabolic waste. Often overlooked the additional complications introduced eventual replenishment, as successful must withstand environmental shifts before swiftly capitalizing on replenished resources avoid invasion competing species. To understand how navigate trade-offs between growth survival, ultimately adapting thrive environments extreme fluctuations, we experimentally evolved 16 Escherichia coli populations for 900 days repeated feast/famine conditions cycles 100-day starvation replenishment. Using longitudinal population-genomic analysis, found that evolution response characterized narrow adaptive trajectories high mutational parallelism notable order.

Abstract Functional trade-offs can affect patterns of morphological and ecological evolution as well the magnitude changes through evolutionary time. Using morpho-functional landscape modelling on cranium 132 carnivore species, we focused macroevolutionary effects trade-off between bite force velocity. Here, show that rates in form (morphology) are decoupled from function. Further, found theoretical morphologies optimising for velocity to be more diverse, while a much smaller phenotypic space was occupied by shapes force. This pattern differential representation different functions highly correlated with actual disparity. We hypothesise many-to-one mapping shape function may prevent detection direct relationships As comparatively only few optimise force, species this less abundant because they likely evolve. This, turn, explain why certain clades variable than others. Given ubiquity functional biological systems, these general help unevenness diversity across tree life.
