Primate Neocortex and Genomic Data for Evolutionary Analysis

Phylogenetic modeling of relative neocortex size across anthropoid primates reveals a significant reduction in the ancestral Callitrichinae + Aotus branch. The dataset includes codon-based tests for positive selection across 18,177 orthologous protein-coding genes, compiled by figshare admin karger and last updated in May 2026. It is a 65.4 KB XLSX file containing results from analyses of neocortex and medulla volumes.

Use Cases

• Phylogenetic comparative analysis based on relative neocortex size data
• Identifying genes under positive selection based on results from aBSREL and RELAX tests
• Functional enrichment analysis based on the list of 12 candidate genes
• Investigating correlations between brain trait evolution and genomic changes based on the described methodology

Strengths

• Includes results from tests on 18,177 orthologous protein-coding genes
• Phylogenetic analyses are based on compiled neocortex and medulla volumes for anthropoid species
• Data is openly available under a CC-BY-4.0 license

Limitations

• Row count is unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
• The 65.4 KB size indicates a very limited scope of data

Collection Method

Volumes were compiled for species; phylogenetic modeling and genomic scans (aBSREL, RELAX) were performed.
