Conclusion: the Cave originates in the A-G linguistic subgroup;
The earliest partially identified cave is at less than 68% with *A* (sindhi),
Followed by a bandgap at 38%.
At 36% the earliest identified caves are Gua (indonesian) and guu (myanmar) followed at 31% with Guhe (kannada), guha (malayalam), and Guhā (bengali). We might conclude the earliest shared cave might have been named Gu* and it's likely located in South East Asia.

A second bandgap occurs at 27% and then caves again become popular at 24% with *R (pashto) and G'or (uzbek). The discovery of caves rises to a peak at 21% before declining down to 1%.
