WebApr 11, 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. WebAn example of homologous characters is the four limbs of tetrapods. Birds, bats, mice, and crocodiles all have four limbs. Sharks and bony fish do not. The ancestor of tetrapods evolved four limbs, and its descendents have inherited that feature — so the presence of four limbs is a homology.
