The analysis of ancient DNA and paleoproteomics can identify biological materials, such as fossils, construct phylogenetic relationships between extinct and extant species, and has been widely applied in archaeology and paleontology. In general, proteins degrade more slowly than DNA and could be persevered in fossils over 60 million. Although less phylogenetic information was obtained than ancient DNA, paleoproteomics analysis becomes an indispensable method for studying biological evolution and hominins behaviours with its high throughput, low cost, and low contamination. Based on several cases of applying paleoproteomics analysis in archaeological and paleontological sites from East Asia, I will present two main methods, LC-MS/MS and MALDI-TOF MS, and how paleoproteomics reveals the evolutionary history and behaviours of hominins in East Asia, aiming to provide a research background of this field.
