Dr Serena Tucci told the BBC: "Like many other scientists, it is my dream to find ancient DNA from the Hobbit. sapiens and Neanderthals.īut, as a BBC News article points out today: " Unfortunately, the wet and tropical conditions on Flores mean that all efforts to isolate hobbit DNA have so far failed. Maybe this has been concluded as the only genetic components are that of Denisovans, H. So the pygmy population that is now living on the island has Denisovan and Neanderthal admixture -but no additional archaic lineages. Thus, multiple independent instances of hominin insular dwarfism occurred on Flores." Modern individuals bear the signatures of recent positive selection encompassing the FADS (fatty acid desaturase) gene cluster, likely related to diet, and polygenic selection acting on standing variation that contributed to their short-stature phenotype. The genomes of Flores pygmies reveal a complex history of admixture with Denisovans and Neanderthals but no evidence for gene flow with other archaic hominins. Here we describe genome-scale single-nucleotide polymorphism data and whole-genome sequences from a contemporary human pygmy population living on Flores near the cave where H. This island is also home to an extant human pygmy population. " Flores Island, Indonesia, was inhabited by the small-bodied hominin species Homo floresiensis, which has an unknown evolutionary relationship to modern humans. Twice because it evolved once in Pygmies in Flores and again (or rather before) in the H. Thus, restricted height is under selection at this location and has evolved independently at least twice in hominins."
These individuals exhibit signatures of polygenic selection explaining the short stature and have genomic content from both Neanderthals and Denisovans, but no additional archaic lineages. examined genetic variation among 32 individuals, including 10 sequenced genomes, from a population of pygmies living close to the cave where H. floresiensis exhibited a diminutive adult size relative to other hominins.
Furthermore, Flores has an extant population of pygmy humans, and H. The background is (quote from the magazine):įlores Island in Indonesia has a long history of hominin occupation, including by the extinct Homo floresiensis and a more recent settlement by modern humans. 511-516.DOI: 10.1126/science.aar8486) tells us that the pygmy-sized Hobbits of Flores island evolved their own short stature independently from the small-sized Homo sapiens that live nowadays in Flores (pygmies).
