482. 石器时代犬类多样性起源
from 知为谁 · host 知为谁
这段文本主要围绕家犬的演化和驯化历史展开，指出家犬的多样性可以追溯到比先前认为更早的石器时代中期。一项新的研究通过分析跨越五万年的六百多个犬科动物头骨，发现大约一万一千年前，即末次冰期之后，狗的头骨形状就开始发生变化，出现了短吻、宽头等特征，这表明现代犬种近一半的多样性在石器时代中期就已存在。研究人员利用数字3D模型比较了古代和现代狗的特定特征，挑战了维多利亚时代育种者驱动了这种多样性的传统观点。此外，另一项对古代DNA的研究证实，家犬的迁移通常与人类群体的迁徙同时发生，表明人与狗的联系已持续了数千年。内容来源：https://www.bbc.com/news/articles/ce9d7j89ykro
