144. 哺乳动物食蚁性进化十二次
from 知为谁 · host 知为谁
该研究揭示了哺乳动物为适应以蚂蚁和白蚁为食的饮食，自恐龙灭绝后独立演化出特化性状至少12次。这项由新泽西理工学院的菲利普·巴登共同领导的研究，追踪了食蚁动物的演变过程，发现这种饮食策略（即蚁食性）的趋同演化与蚂蚁和白蚁群体在非鸟类恐龙灭绝后迅速扩张的时期相吻合。研究强调了社会性昆虫对哺乳动物进化产生的强大选择压力，但也指出一旦适应这种饮食，哺乳动物很少会恢复到更传统的食性，这可能导致一些物种面临进化上的“死胡同”。内容来源：https://news.njit.edu/mammals-evolved-ant-eaters-12-times-dinosaur-age-study-finds
