EVOLUTION, SKELETON, PHYLOGENY, MORPHOLOGY, MAMMALS. Research objects: Taxa: chiropterans, cetaceans, including extant and extinct baleen whales, toothed whales, “archaeocetes”, representatives of closely related taxa (outgroups). Structures: skeleton elements – skull, hyoid, vertebrae, ribs, sternum, girdles and limbs, teeth; genes: 5’-end Hox-genes. Project aim: overall aim is identification of ways of integration and transformation, sources of evolutionary novelties in mammalian skeleton systems during their transition to aerial and aquatic ways of life. The project is focused on research of skeleton structures as the most conservative elements, which are convenient models for study of evolutionary process. It is specially focused on processes of ontogeny prolongation in groups which are known for their body size disparity and longevity. The second stage of project implementation in 2021 includes collection and primary processing of morphological data from American and European research institutions, phylogenetic analyses of coding sequences, analysis of morphological and genetic data. Research methods: traditional and geometric morphometry, multidimensional morphological modelling; data collection – 3D surface scanning, photography, measurements. Microscopy and CT. Mathematical methods: factor analysis, phylogenetic analysis, graph analysis, leading eigenvector algorithm. Bioinformatics: annotation of target sequences in open databases, identification and prediction of nucleotide and protein sequences, identification of natural selection parameters, data analysis.
