研究人员说,现代人类与大脑进化有独特的手指长度比。 Modern humans have a unique finger length ratio linked to brain evolution, researchers say.

一项新的研究表明,手指长度比率与人类大脑进化之间有联系,这表明,用环手指比较指数的相对长度可能反映随着时间推移的大脑发育变化。 A new study suggests a link between finger length ratios and human brain evolution, indicating that the relative length of the index to ring finger may reflect changes in brain development over time. 研究人员分析了骨骼残骸,发现现代人类与古老的荷尔蒙相比有明显的比例,可能与产前荷尔蒙接触和认知演变有关。 Researchers analyzed skeletal remains and found that modern humans have a distinct ratio compared to ancient hominins, potentially tied to prenatal hormone exposure and cognitive evolution. 研究结果为了解人类大脑如何演化提供了可能的生物标志。 The findings offer a possible biological marker for understanding how human brains evolved.
