The phylogenetic interrelationships of Cervidae (deer) have been the focus in many studies, but results are controversial and no definitive reconstruction yet exists. Critical issues include insufficient taxon and character sampling as well as heterogeneous data. Here we aim to compile a large data matrix considering all extant and many extinct species, combining molecular and morphological data. Morphology of hard tissues is fundamental to enable a simultaneous analysis of palaeontological and neontological data. Molecular data are easily obtainable for living species and are essential for reconstructing the tree of life. Our groups have access to both data sources and the methodologies to interpret them. With such a data matrix we expect to establish the hitherto largest set of characters in order to estimate cervid phylogeny. Systematic results will be used to solve long-standing questions of cladogenetic events in cervid evolution. Working hypotheses to be tested comprise the phenotype of the last common ancestor of cervids and cervid origination as well as mutual reaction of climatic conditions and cervid diversification / dispersal.

鹿科（鹿）的系统发育相互关系一直是许多研究的焦点，但结果存在争议，尚未有明确的重建。关键问题包括分类单元和字符采样不足以及异构数据。在这里，我们的目标是编制一个大的数据矩阵考虑所有现存和许多灭绝的物种，结合分子和形态数据。硬组织形态学是古生物学和新学数据同时分析的基础。现存物种的分子数据很容易获得，对重建生命之树至关重要。我们的团队可以访问数据源和解释它们的方法。有了这样的数据矩阵，我们期望建立迄今为止最大的特征集，以便估计鹿科的系统发育。系统的结果将用于解决长期存在的问题，分支发育事件在蜥蜴进化。有待测试的工作假设包括鹿科动物最后共同祖先的表型和鹿科动物的起源，以及气候条件和鹿科动物多样化/扩散的相互反应。
