Response to comment on “Sexual selection promotes giraffoid head-neck evolution and ecological adaptation”

This is the authors' abstract. We don't add key points for this paper.

Hou et al . challenged the giraffoid affinity of Discokeryx and its ecology and behavior. In our response we reiterate that Discokeryx is a giraffoid that, along with Giraffa , shows extreme evolution of head-neck morphologies that were presumably shaped by selective pressure from sexual competition and marginal environments.
