The video tutorial explains the construction of an evolutionary tree based on DNA homology. It covers the comparison of DNA sequences among five species to determine genetic similarity and dissimilarity. The tutorial demonstrates how to create a dissimilarity table and form clusters using the UPGMA method. Finally, it shows the construction of a phylogenetic tree, highlighting the genetic distances between species.
