Evolution of pheno- and genotype diversity in Cervidae (Ruminantia, Artiodactyla, Mammalia)

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，还没有确定的重建。关键问题包括分类群和特征采样不足以及数据的异质性。在这里，我们的目标是编制一个大型数据矩阵，考虑所有现存的和许多灭绝的物种，结合分子和形态数据。硬组织的形态是能够同时分析古生物和新生物数据的基础。对于活着的物种来说，分子数据是很容易获得的，并且对于重建生命之树是必不可少的。我们的小组可以获得数据来源和解释它们的方法。有了这样的数据矩阵，我们希望建立迄今为止最大的特征集，以估计鹿科动物的系统发育。系统的结果将被用来解决鹿类进化中分支发生事件的长期问题。有待检验的工作假设包括最后一个共同祖先的表型和宫颈起源，以及气候条件和宫颈多样化/扩散的相互反应。

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.
