研究显示早期哺乳动物有深棕色毛皮 以帮助他们在夜间躲避掠食者 Study reveals early mammals had dark, brown fur to help them hide from predators at night.

最近发表在《科学》上的一项研究表明,与恐龙一起生活的早期哺乳动物有着相同的黑色棕色毛皮,这有助于他们融入夜间环境和避免捕食者。 A recent study published in Science suggests that early mammals living alongside dinosaurs had uniformly dark, brown fur which helped them blend into nocturnal environments and avoid predators. Ghent大学的研究人员使用化石成像方法检查6个早期哺乳动物的造色细胞,发现它们的毛皮颜色主要是灰褐色。 Researchers from Ghent University used fossil imaging methods to examine the pigment-producing cells of six early mammals, finding that their fur color was mainly greyish-brown. 与现代哺乳动物更为多样的模式形成对比的是,这种暗色的颜色可能为生存提供了优势。 This dark coloring likely provided a survival advantage, contrasting with the more varied patterns of modern mammals.
