Macroevolutionary Patterns of Endocast Lateralization in Catarrhines and Fossil Hominins

Supplementary material for a study analyzing brain shape lateralization across 81 catarrhine species, including apes, humans, and fossil hominins. The dataset, authored by figshare admin karger and last updated in May 2026, comprises a 1.4 MB DOCX file. It supports research on the evolutionary rates of asymmetric endocranial shape using 3D geometric morphometrics and phylogenetic ridge regression.

Use Cases

• Modeling macroevolutionary rates of asymmetric shape change based on phylogenetic ridge regression methods described.
• Comparing endocast lateralization patterns between hominin and non-human ape lineages as a core study focus.
• Investigating the spatial concentration of evolutionary changes on the endocranial surface mentioned in the results.
• Testing hypotheses linking structural brain reorganization to lateralized shape evolution during hominin evolution.

Strengths

• Explicit phylogenetic framework applied to a comparative sample of 81 extant and extinct species.
• Analysis based on 161 cranial endocasts using high-resolution 3D geometric morphometrics.
• Quantifies rates of asymmetric shape change directly mapped onto the cortical surface.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is contained in a DOCX file (1.4 MB), which may require extraction or conversion for computational analysis.
