Gecko fact
Genetic surveys have traced exactly which clonal lineages colonised different island chains
Good to know
Quick answer
A study of Japanese island populations found the Ogasawara Islands host only a single diploid clonal lineage likely introduced after World War II, while the Ryukyu Islands host a different, triploid lineage — a level of detail that shows how recently and specifically these populations trace back to particular founder events..
