Argentina
This map is entirely wrong. Argentina is mostly populated by Spanish people and Iceland is Norse, yet look at what the map says. Should be deleted. — Preceding unsigned comment added by 142.162.156.164 (talk) 23:41, 21 August 2017 (UTC)

Sardinia
Hi guys, the map is really cool but I think it would benefit a great deal from a few numbers extrapolated from a specific study on lactase persistence (Y. Itan, B.L. Jones, C.J. Ingram, D.M. Swallow, M.G. Thomas; A worldwide correlation of lactase persistence phenotype and genotypes, BMC Evolutionary Biology, 10 (1) (2010), pp.10-36); it appears that among the Sardinians, who also form a genetic isolate in Europe, the value of non-persistence lactase increases up to 85%. On average, as confirmed by a 2007 research by the Brotzu, 8 out of ten Sardinians are lactose intolerant. It might therefore be argued that Sardinia should display a different colour, the bluest one.Dk1919 (talk) 01:26, 21 April 2018 (UTC)
