由于气候变化, 格陵兰东南部北极熊的基因突飞猛进, 但科学家说,若不紧急削减碳排放量, Polar bears in southeastern Greenland are rapidly evolving genetically due to climate change, but scientists say these changes won’t prevent extinction without urgent carbon cuts.

根据东安格利亚大学的一项研究,格陵兰东南部的北极熊正在显示与气候变化有关的迅速基因变化,包括“跳跃基因”活动增加,可能帮助他们适应更暖的温度、减少海冰和改变饮食。 Polar bears in southeastern Greenland are showing rapid genetic changes linked to climate change, including increased activity of "jumping genes" that may help them adapt to warmer temperatures, reduced sea ice, and shifting diets, according to a University of East Anglia study. 研究人员发现,这些基因转移,特别是在与热应激和新陈代谢有关的基因方面,在面临更大环境压力的南部熊中更为明显。 Researchers found these genetic shifts, particularly in genes related to heat stress and metabolism, were more pronounced in southern bears facing greater environmental stress. 虽然研究结果表明,有一定的进化适应潜力,但科学家强调这些变化不足以抵消长期威胁,并强调减少碳排放对于防止灭绝仍然至关重要。 While the findings suggest some potential for evolutionary adaptation, scientists stress these changes are insufficient to offset long-term threats and emphasize that cutting carbon emissions remains critical to preventing extinction.
