从怪兽到长颈鹿:獬豸盘角鹿研究漫谈

From Beast to Giraffe:The Study of Discokeryx xiezhi

长颈鹿长脖子的演化是演化生物学的旗帜性问题,从拉马克的用进废退、达尔文的自然选择,到今天的性选择,多种学术观点共同完善了对这一问题的认识。獬豸盘角鹿化石的发现和研究,代表了传统学术观点的新综合。

Discokeryx xiezhi was an early giraffoid with very thick neck bones for head-butting, a fierce intermale mating competition. The new fossil provides an example for interpreting the long neck evolution of the living giraffe.
