Combining morphological and DNA sequence data for phylogenetic analysis

I'm an evolutionary biologist based in the Department of Zoology, University of Cambridge (www.robertjasher.com). Here I describe very basic steps to join phylogenetic data typical in paleontology (morphological characters) with DNA sequences from living species in order to make a phylogenetic estimate of fossils in the context of their living relatives. In this exercise I use nexus format and draw mostly from these data sources and software packages: Huttenlocker et al. 2018: https://www.nature.com/articles/s4158... Upham et al. 2019: https://www.ncbi.nlm.nih.gov/pmc/arti... Asher 2007: http://www.biomedcentral.com/1471-214... and http://www.robertjasher.com/database/...
