第91期: 古墓里的羽毛 - DNA和同位素的破案

from 鸟瘾综合征

在秘鲁海岸的千年古墓里,科学家发现了鲜艳的鹦鹉羽毛。可是这些羽毛的主人,像是绯红金刚鹦鹉等等,可不是本地人,它们的老家是在安第斯山脉东侧的亚马逊雨林。这些羽毛又是如何出出现在这个古墓里呢?为了破案,研究人员使用了两项技术破解了谜题。古DNA分析显示,这些羽毛的基因多样性很高,和已知圈养种群的特征不符,证明它们是来自于亚马逊雨林的野生种群,是被捕捉的,而不是本地养殖的。可是,案情并不完整。科学家又进一步运用了稳定同位素分析。证明他们确实不是本地的鸟,但是又在本地讨生活....古墓的地点经过1000年,色彩还是很漂亮啊参考文献George Olah et al.(2026).
