研究指出, 一只松鼠可能印了芝加哥的“老鼠洞”印记。 A squirrel likely made Chicago’s "Rat Hole" imprint, study says.

根据一项新的研究,芝加哥Roscoe村的神秘人行道印记曾被称为“老鼠洞”,被广泛认为是一只大鼠所造,很可能是由松鼠造成的。 A mysterious sidewalk imprint in Chicago’s Roscoe Village, once dubbed the "Rat Hole" and widely believed to be made by a large rodent, was likely created by a squirrel, according to a new study. 研究人员分析了该标记的形状,并将其与当地鼠类物种进行比较,发现该标记与东灰松鼠的含量为98.67%。 Researchers analyzed the mark’s shape and compared it to local rodent species, finding a 98.67% match with the eastern gray squirrel. 他们的结论是,动物在爬树时可能掉进湿水泥里,留下几乎完美的身体印象。 They concluded the animal probably fell into wet concrete while climbing a tree, leaving a near-perfect body impression. 该研究发表在《生物学信》上,强调科学分析如何能澄清病毒性互联网奥秘。 The study, published in Biology Letters, highlights how scientific analysis can clarify viral internet mysteries. 原始板块被移到芝加哥市政厅 作为当地的一种好奇心 The original slab was moved to Chicago City Hall as a local curiosity.
