Latif Nasser: 我讲述了一个关于骆驼的故事,一个我们熟悉却对其进化史知之甚少的物种。这个故事始于一位古生物学家Natalia Rybczynski在北极发现的一块远古骆驼骨骼,这颠覆了我们对骆驼起源的认知。我们通常认为骆驼是沙漠动物,但实际上,骆驼起源于北美洲,并在那里进化了数百万年,才最终迁移到亚洲和非洲的沙漠地区。这块骨骼的发现,以及对骆驼身体特征的深入研究,揭示了骆驼惊人的适应性,以及它们在不同环境中的生存策略。 我采访了在威斯康星州饲养骆驼的Shane Rigdon,他分享了他在冬季观察骆驼在雪地里玩耍的经历,这进一步佐证了Natalia Rybczynski的理论:骆驼许多看似适应沙漠环境的特征,实际上也使其能够在寒冷的雪地中生存。例如,骆驼的长睫毛可以阻挡雪暴中的飞雪,坚硬的嘴巴可以吃下带刺的植物,宽大的脚掌像雪鞋一样防止陷入雪地,驼峰储存的脂肪则提供能量和保暖。 总而言之,骆驼的进化故事是一个充满惊喜和启迪的故事,它告诉我们,物种的适应性远比我们想象的更强大,生存的方式也多种多样。 Natalia Rybczynski: 我在加拿大埃尔斯米尔岛进行研究时,发现了一块350万年历史的骨头碎片,起初我以为是植物化石,但仔细观察后发现是骨头。经过分析,这块骨头属于一种大型动物。经过多年的研究,我最终确认这块骨头属于骆驼。这一发现极大地挑战了我们对骆驼起源的认知,也揭示了骆驼惊人的适应性。骆驼最初起源于北美洲,并在那里进化出许多适应寒冷气候的特征,这与我们通常认为骆驼是沙漠动物的认知大相径庭。 Shane Rigdon: 我在威斯康星州的农场饲养骆驼,我发现骆驼非常喜欢雪地,它们在雪地里玩耍,表现出极大的快乐。这与Natalia Rybczynski的理论相符,骆驼许多看似适应沙漠环境的特征,实际上也使其能够在寒冷的雪地中生存。例如,骆驼的长睫毛可以阻挡雪暴中的飞雪,宽大的脚掌像雪鞋一样防止陷入雪地,驼峰储存的脂肪则提供能量和保暖。 Lulu Miller: 作为节目的主持人,我参与了对骆驼进化故事的讲述,并亲身体验了骑骆驼在雪地里行走的乐趣。这个故事让我对物种的适应性和生存能力有了更深刻的理解。 Alan Goffinski: 我参与了节目的制作,并为节目创作了音乐。骆驼的故事是一个充满惊喜和启迪的故事,它告诉我们,物种的适应性远比我们想象的更强大,生存的方式也多种多样。

Shownotes Transcript

Today we bring you a story stranger than fiction. In 2006, paleobiologist Natalia Rybczynski) took a helicopter to a remote Arctic island near the North Pole, spending her afternoons scavenging for ancient treasures on the ground. One day, she found something the size of a potato chip. Turns out, it was a three and half million year old chunk of bone. 

Keep reading if you’re okay with us spoiling the surprise.

It’s a camel! Yes, the one we thought only hung out in deserts. Originally from North America, the camel trotted around the globe and went from snow monster to desert superstar. We go on an evolutionary tour of the camel’s body and learn how the same adaptations that help a camel in a desert also helped it in the snow. Plus, Lulu even meets one in the flesh. 

Special thanks to Latif Nasser for telling us this story. It was originally a TED Talk) where he brought out a live camel on stage. Thank you also to Carly Mensch, Juliet Blake, Anna Bechtol, Stone Dow, Natalia Rybczynski and our camel man, Shayne Rigden. If you are in Wisconsin, you can go meet his camels at Rigden Ranch). And follow his delightful TikTok @rigdenranch) to see camels in the snow!
