城市浣熊的鼻孔较短,表明由于城市生活的原因,早期的家养式进化也与城市生活相似。 Urban raccoons show shorter snouts, suggesting early domestication-like evolution due to city life.

美国各地的城市浣熊可能表现出早期的家养迹象,生物学家Raffaela Lesch观察到,与农村相比,居住在城市的浣熊的鼻孔较短。 Urban raccoons across the U.S. may be showing early signs of domestication, with biologist Raffaela Lesch observing shorter snouts in city-dwelling raccoons compared to rural ones. 在分析超过19,000张照片时,她的团队发现鼻孔长度减少了3.6%,与其他动物的驯化有关。 Analyzing over 19,000 photos, her team found a 3.6% reduction in snout length, a trait linked to domestication in other animals. 这一转变可能是由获得人类食物和减少对人的恐惧所驱动的,可能反映了与狗和猫类似的进化变化。 This shift, possibly driven by access to human food and reduced fear of people, may reflect evolutionary changes similar to those in dogs and cats. 虽然尚未被驯化，但研究结果表明，浣熊正在以类似驯化的方式适应城市生活，尽管需要进一步研究以确认遗传性和更广泛的模式。 While not yet domesticated, the findings suggest raccoons are adapting to urban life in ways that mirror domestication, though further research is needed to confirm heritability and broader patterns.
