# The haplotype of the lineage from the island of Rabida is nested within haplotypes found in extant species from the island of Isabela [16], supporting an early speculation that the Rabida tortoise did not belong to a distinct species, but rather to tortoises collected elsewhere and consumed by sailors on Rabida [8].
