Webb13 jan. 2005 · The main proposed adaptationist explanation for the function of redundant (noncoding) DNA is the ‘skeletal DNA’ hypothesis, which suggests that selection for cell size is the primary cause and that genome size is the result of selection for an optimal nucleocytoplasmic ratio (Cavalier-Smith 1978, 1985; Beaton and Cavalier-Smith 1999; … WebbThis skull (cast) is part of a fairly complete unfossilised skeleton of Homo floresiensis known as LB1. It is the type specimen of the species and dates to between 100,000 and 60,000 years old. The other skeletal remains of LB1 include leg bones, parts of the pelvis, hands and feet, and some other fragments.
