Research framework
Phylogenetic and selection analysis may answer distant questions such as when and how a taxonomic group dispersed and colonized its present distribution, if their differences can be called interspecific, when and how many times homologous genes originated or went through duplications and deletions, what was the chromosome number of the ancestor of a karyotypically unstable group, how genetic differentiation may alter virus positive detection, or how do co-diversification and host shifts shape virus evolution. These are just a few, among a virtually unlimited number of questions that could be addressed using evolutionary trees.
I have addressed these kinds of questions by integrating nucleotide sequences, fossil calibrations, and evolutionary models, with special emphasis in mammals (rodents and bats), and zoonotic viruses (rabies and coronavirus).
