5700年前生活在现今丹麦洛兰岛希尔索姆(Syltholm)附近的少女“罗拉”(Lola)，有深色头发、深色皮肤和蓝色眼睛，有乳糖不耐症，可能也有牙周病—这些都是从一块新石器时代留下的桦树焦油中所含去氧核糖核酸(DNA)得知的线索。

哥本哈根大学全球研究所研究人员日前在“自然通讯”期刊发表报告，在希尔索姆挖掘出这块两公分长的焦油，有如“时光胶囊”般透露当时人类的生物特征、生活习惯等资讯。

旧石器时代人类已会使用桦树焦油当黏著剂，但可能也当作“口香糖”或牙刷。报告作者、分子人类学家施洛德(Hannes Schroeder)说，“这是首次从人类骨骸以外的物品，得出完整的远古人类基因”，令人大感意外。
