These visualizations are powered by a comprehensive dataset of world language evolution, featuring:

22 Language Families - Including Indo-European, Sino-Tibetan, Niger-Congo, Afro-Asiatic, Austronesian, and more
15 Language Isolates - Basque, Sumerian, Burushaski, Ainu, Korean, and others with no proven relatives
9 Macro-Family Hypotheses - Nostratic, Dene-Yeniseian, Austric, and other proposed deep-time groupings
Confidence Scores - Quantitative assessment of classification reliability (0.0-1.0)
Bayesian Dating - Proto-language divergence dates with uncertainty ranges (BP ± σ)
Archaeological Correlations - Links to material cultures (Yamnaya, Tapenkeng, Natufian, etc.)
Geographic Data - Homeland coordinates and expansion patterns
Current Terminology - Uses accepted academic terms and documents controversies

Data Sources: Glottolog, academic research papers, Bayesian phylogenetic studies, and archaeological evidence.

All visualizations are built with:
