It has been suggested that advanced tool behaviour co-evolves with a suite of behavioural, morphological and life history traits. In fact, there are indications for such an adaptive complex in tool-using crows (genus Corvus species). Here, we sequenced the genomes of two habitually tool-using and ten non-tool-using crow species to search for genomic signatures associated with a tool-using lifestyle. Using comparative genomic and population genetic approaches, we screened for signals of selection in protein-coding genes in the tool-using New Caledonian and Hawaiian crows. While we detected signals of recent selection in New Caledonian crows near genes associated with bill morphology, our data indicate that genetic changes in these two lineages are surprisingly subtle, with little evidence at present for convergence. We explore the biological explanations for these findings, such as the relative roles of gene regulation and protein-coding changes, as well as the possibility that statistical power to detect selection in recently diverged lineages may have been insufficient. Our study contributes to a growing body of literature aiming to decipher the genetic basis of recently evolved complex behaviour.", "doi": "10.1111/mec.15775", "pmid": "33305388", "labels": [], "xrefs": [{"db": "Dryad", "key": "10.5061/dryad.w0vt4b8m9"}], "notes": [], "created": "2026-08-21T12:20:44.800Z", "modified": "2026-08-21T12:20:45.115Z"}, {"entity": "publication", "iuid": "ef453fa8bfeb46daaca4c1db0b124dab", "links": {"self": {"href": "https://publications-affiliated.scilifelab.se/publication/ef453fa8bfeb46daaca4c1db0b124dab.json"}, "display": {"href": "https://publications-affiliated.scilifelab.se/publication/ef453fa8bfeb46daaca4c1db0b124dab"}}, "title": "Demographic histories and genetic diversity across pinnipeds are shaped by human exploitation, ecology and life-history.", "authors": [{"family": "Stoffel", "given": "M A", "initials": "MA"}, {"family": "Humble", "given": "E", "initials": "E"}, {"family": "Paijmans", "given": "A J", "initials": "AJ", "orcid": "0000-0002-5481-7337", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/ce69dffcbe3f47a19542e8957089c2d1.json"}}, {"family": "Acevedo-Whitehouse", "given": "K", "initials": "K"}, {"family": "Chilvers", "given": "B L", "initials": "BL"}, {"family": "Dickerson", "given": "B", "initials": "B"}, {"family": "Galimberti", "given": "F", "initials": "F", "orcid": "0000-0001-5537-6409", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/47021e09eab34879a2ef125d01a99a7d.json"}}, {"family": "Gemmell", "given": "N J", "initials": "NJ", "orcid": "0000-0003-0671-3637", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/eb6770c24f6840e8a271aeb00b79e88d.json"}}, {"family": "Goldsworthy", "given": "S D", "initials": "SD"}, {"family": "Nichols", "given": "H J", "initials": "HJ"}, {"family": "Kr\u00fcger", "given": "O", "initials": "O"}, {"family": "Negro", "given": "S", "initials": "S"}, {"family": "Osborne", "given": "A", "initials": "A"}, {"family": "Pastor", "given": "T", "initials": "T"}, {"family": "Robertson", "given": "B C", "initials": "BC"}, {"family": "Sanvito", "given": "S", "initials": "S", "orcid": "0000-0003-1427-6414", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/c6901273372d4e9faca7c1ff468c9330.json"}}, {"family": "Schultz", "given": "J K", "initials": "JK"}, {"family": "Shafer", "given": "A B A", "initials": "ABA"}, {"family": "Wolf", "given": "J B W", "initials": "JBW"}, {"family": "Hoffman", "given": "J I", "initials": "JI"}], "type": "historical article", "published": "2018-11-16", "journal": {"title": "Nat Commun", "issn": "2041-1723", "volume": "9", "issue": "1", "pages": "4836", "issn-l": "2041-1723"}, "abstract": "A central paradigm in conservation biology is that population bottlenecks reduce genetic diversity and population viability. In an era of biodiversity loss and climate change, understanding the determinants and consequences of bottlenecks is therefore an important challenge. However, as most studies focus on single species, the multitude of potential drivers and the consequences of bottlenecks remain elusive. Here, we combined genetic data from over 11,000 individuals of 30 pinniped species with demographic, ecological and life history data to evaluate the consequences of commercial exploitation by 18th and 19th century sealers. We show that around one third of these species exhibit strong signatures of recent population declines. Bottleneck strength is associated with breeding habitat and mating system variation, and together with global abundance explains much of the variation in genetic diversity across species. Overall, bottleneck intensity is unrelated to IUCN status, although the three most heavily bottlenecked species are endangered. Our study reveals an unforeseen interplay between human exploitation, animal biology, demographic declines and genetic diversity.", "doi": "10.1038/s41467-018-06695-z", "pmid": "30446730", "labels": [], "xrefs": [{"db": "pmc", "key": "PMC6240053"}, {"db": "pii", "key": "10.1038/s41467-018-06695-z"}], "notes": [], "created": "2026-08-21T11:48:07.177Z", "modified": "2026-08-21T11:48:07.330Z"}]}
