研究发现,193万年的Kākāp鹦鹉演变成绿色和橄榄羽毛,以躲避灭绝的捕食者。 1.93 million-year-old Kākāpō parrot evolved green and olive feathers to evade extinct predators, study finds.

新西兰濒临绝境的Kākāp鹦鹉演变成两种羽毛颜色, 绿色和橄榄, 以躲避哈斯特鹰等灭绝鸟类的掠夺。 A study in PLOS Biology reveals that New Zealand's critically endangered Kākāpō parrot evolved two feather colors, green and olive, to evade predation by extinct birds like the Haast's eagle. 研究人员通过分析168名个人提供的基因组数据发现,由于视觉狩猎压力,这些颜色变化在193万年前出现。 Analyzing genome data from 168 individuals, researchers found these color variations emerged about 1.93 million years ago due to visual hunting pressures. 了解这一演变可能有助于养护工作,因为30代人不干预,物种可能丧失颜色多样性。 Understanding this evolution may aid conservation efforts, as the species could lose color diversity without intervention in 30 generations.
