人类祖先可能很早“走出非洲”进化过程或更加复杂

  今日IT讯 近日,一个由瑞典和波兰等国科研人员组成的团队,在英国的《地质学家协会学报》发表声明称,他们发现的脚印化石出土于克里特岛西部,沉积物和微体化石分析表明它们形成于570万年前。

  正常情况下,科学界普遍认为人类祖先诞生于非洲,直到约200万年前才有第一批人科物种迁徙出非洲。但本次的研究团队认为,他们发现的脚印更像人类留下的,尤其是大脚趾的形状、大小和朝向。克里特岛发现的脚印化石比地猿始祖种还早100多万年,却有着明显的人类特征,意味着人类进化过程比原先认为的更加复杂。不过,这批脚印能否作为原始人类迹象的坚实证据被科学界所接受,还有待观察。
