Transition-Transversion Bias and Metabolic Rate Data for Birds and Mammals

438 KB of data files in DOCX and XLSX formats authored by Svyatoslav Morozov-Leonov and last updated in April 2026. The dataset supports a study on the relationship between evolutionary mutation bias and metabolic rate, comparing birds and mammals across different body sizes. It provides direct support for the metabolic theory of evolution and indirect support for the evolutionary speed hypothesis.

Use Cases

• Test the metabolic theory of evolution based on the relationship between mutation bias and metabolic rate.
• Compare evolutionary rates between birds and mammals based on transition-transversion bias data.
• Investigate the link between body size, metabolic intensity, and molecular evolution rates.
• Analyze factors contributing to species richness differences between taxonomic groups.

Strengths

• Data is structured in Excel (XLSX) and document (DOCX) formats, totaling 438 KB.
• Dataset is openly licensed under CC-BY-4.0, allowing for reuse and redistribution.
• The study provides specific findings, such as higher transition-transversion bias in mammals than in birds.

Limitations

• Row count and column-level documentation are unknown, requiring inspection after download.
• The dataset's small size (438 KB) suggests a limited scope, potentially covering a specific set of families or genes.
• Description metadata is limited; actual data quality requires manual inspection after download.
