Species with larger brains relative to their body size have slower life histories, with reduced output per reproductive event and delayed development times that can be offset by increasing behavioral flexibility. The \"cognitive buffer\" hypothesis maintains that large brain size decreases extrinsic mortality due to greater behavioral flexibility, leading to a longer lifespan. Alternatively, slow life histories, and long lifespan can be a pre-adaptation for the evolution of larger brains. Here, we use phylogenetic path analysis to contrast different evolutionary scenarios and disentangle direct and indirect relationships between brain size, body size, life history, and longevity across 339 altricial and precocial bird species. Our results support both a direct causal link between brain size and lifespan, and an indirect effect via other life history traits. These results indicate that large brain size engenders longer life, as proposed by the \"cognitive buffer\" hypothesis.","is_dataset_classified":null,"base_score":3.970291913552122,"endowment":3.970291913552122,"datacite_reuse_total":1,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"32840865","pmcid":null,"openalex_id":"https://openalex.org/W3080824612","authors":[],"funders":[{"funder_name":"Consejo Nacional de Ciencia y Tecnología","grant_id":"704115","title":null},{"funder_name":"Royal Society: Newton Advanced Fellowhsip","grant_id":"NA150257","title":null}],"total_grants":2,"fwci":12.8458,"citation_percentile":0.98826609,"influential_citations":0,"citation_trend":[{"year":2020,"count":4},{"year":2021,"count":9},{"year":2022,"count":15},{"year":2023,"count":7},{"year":2024,"count":3},{"year":2025,"count":10},{"year":2026,"count":3}],"oa_status":"bronze","license":"http://doi.wiley.com/10.1002/tdm_license_1.1","oa_locations":[{"url":"https://academic.oup.com/evolut/article-pdf/74/12/2617/47720688/evolut2617.pdf","host_type":"journal"},{"url":"https://academic.oup.com/evolut/article-pdf/74/12/2617/47720688/evolut2617.pdf","host_type":"publisher"},{"url":"https://onlinelibrary.wiley.com/doi/pdf/10.1111/evo.14087","host_type":"publisher"},{"url":"https://onlinelibrary.wiley.com/doi/full-xml/10.1111/evo.14087","host_type":"publisher"},{"url":"https://doi.org/10.1111/evo.14087","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/32840865","host_type":"repository"}],"fields_of_study":["Paleontology and Evolutionary Biology","Animal Behavior and Reproduction","Evolution and Paleontology Studies","Animals","Biological Evolution","Birds","Brain","Longevity","Organ Size"],"mesh_terms":["Animals","Birds","Brain","Biological Evolution","Longevity","Organ Size"],"keywords":["Biology","Precocial","Altricial","Brain size","Life history theory","Longevity","Life history","Evolutionary biology","Adaptation (eye)","Encephalization","Flexibility (engineering)","Zoology","Ecology","Neuroscience","Genetics","Phylogenetic Path Analysis","Cognitive Buffer Hypothesis"],"sdg_mappings":[],"linked_datasets":[{"doi":"10.5061/dryad.sqv9s4n27","title":"Brain size and life history variables in birds","publisher":"Dryad","resource_type":"Dataset"}],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-02T17:09:06.901809Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
