Genomic and Morphological Data for Camarhynchus Tree Finches

Whole-genome and morphological data for Camarhynchus tree finches, a clade of Darwin's finches, to study speciation and phenotypic evolution. The dataset, 2.6 GB in size, was authored by Matteo Sebastianelli and last updated in May 2026. It includes files in XLSX, TXT, TSV, and phylogenetic formats (NEXUS, TREES).

Use Cases

• Study the genetic basis of beak and body size variation based on the identified G03 supergene.
• Analyze patterns of speciation with gene flow based on whole-genome sequence data.
• Investigate the role of introgression in adaptive radiation using phylogenetic context.
• Correlate shallow genetic divergence with striking morphological differences mentioned in the description.

Strengths

• Dataset size is 2.6 GB, indicating substantial genomic content.
• Includes multiple data formats (XLSX, TXT, TSV, GZ, NEXUS) for varied analysis.
• Focuses on a specific, recent clade (Camarhynchus) within a classic model system.
• License is CC-BY-4.0, permitting broad reuse with attribution.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Description metadata is limited; actual data quality requires manual inspection after download.
