Through phylogenetics, we learn not only how the sequences came to be the way they are today, but also general principles that enable us to predict how they will change in the future. Webb11 apr. 2024 · Phylogenetic tree construction is a complex process that involves several steps: 1. Selection of molecular marker. The first step in constructing a phylogenetic tree is to choose the appropriate molecular marker. The choice of molecular marker depends on the characteristics of the sequences and the purpose of the study. open switchback stairs
