Phylogenetics of dependence, and dependence of phylogenies

Participants: Wandrille Duchemin, Eric Tannier

Standard phylogenetics use DNA or protein sequences, along with probabilistic models of substitutions, which are Markov processes on trees. The big default of this methodology is to assume a common evolution of all sites inside a gene, and a total independence with other genes. This model does not capture the essence of living things, which is made of dependencies and interactions. We made several methodological developments to take into account these dependencies, by improving the gene tree species tree reconciliation methods and reconstructing phylogenies of relations between genes.
