 The first description of island's demographics by Jacob Roggeveen in 1722 still claimed that the population consisted of two distinctive ethnic groups, one being clearly Polynesian and the other "white" with so lengthened earlobes that they could tie them behind their necks.Roggeveen also noted how some of the islanders were "generally large in stature".Islanders' tallness was also witnessed by the Spanish who visited the island in 1770, measuring heights of 196 and 199 cm (6.4 and 6.5 ft).
