Two recent studies in BMC Biology and Evolution raise important questions about a textbook case of frequency-dependent selection in scale-eating cichlid fishes. They also suggest a fascinating new line of research testing the effects of handed behavior on morphological asymmetry.
发表在《BMC生物学》和《进化》杂志上的两项最新研究,对食鳞丽鱼中频率依赖型选择的一个典型案例提出了重要问题。它们还提出了一个引人入胜的新研究方向,即测试用手行为对形态不对称的影响。
