N2  - Paleoanthropology can provide a lot of important information about body size, sexual dimorphism, locomotion, hand function, feeding ecology etc. of the last common ancestor of great apes and early hominids (LCA). But the fossils can reveal only limited information about LCA social organization or social behaviour. Reconstructions of the communicatory signals phylogeny are frequently based on observations of the living primates. This paper discusses a new type of evidence for homologizing human and primate facial displays. The proposed new approach uses human neuro-cognitive decoding abilities for the primate facial displays. There is an assumption that facial displays which will be interpreted more accurately than others, should be rather homological with some of human facial expressions. Results of the preliminary study involving recognition of chimpanzee facial expressions are evaluated with integration of the previous research.
