Atkinson (Reports, 15 April 2011, p. 346) concluded that language originated in western Africa and that, due to a serial founder effect, languages repeatedly lost phonemes the farther they moved from the African point of origin. Independent examination of the published data tends to refute both these claims.
阿特金森(Reports,2011 年 4 月 15 日,第 346 页)得出结论,语言起源于西非,由于连续的奠基者效应,语言离非洲起源地越远,就会反复失去音位。对已发表数据的独立检验往往驳斥了这两种说法。
