%X The commonplace sequencing of Neanderthal, Denisovan and ancient modern human DNA continues to revolutionize our understanding of hominin phylogeny and interaction(s). The challenge with older fossils is that the progressive fragmentation of DNA even under optimal conditions, a function of time and temperature, results in ever shorter fragments of DNA. This process continues until no DNA can be sequenced or reliably aligned. Ancient proteins ultimately suffer a similar fate, but are a potential alternative source of biomolecular sequence data to investigate hominin phylogeny given their slower rate of fragmentation. In addition, ancient proteins have been proposed to potentially provide insights into in vivo biological processes and can be used to provide additional ecological information through large scale ZooMS (Zooarchaeology by Mass Spectrometry) screening of unidentifiable bone fragments. However, as initially with ancient DNA, most ancient protein research has focused on Late Pleistocene or Holocene samples from Europe. In addition, only a limited number of studies on hominin remains have been published. Here, an updated review on ancient protein analysis in human evolutionary contexts is given, including the identification of specific knowledge gaps and existing analytical limits, as well as potential avenues to overcome these.
