| مستخلص: | Phylogenetics is a scientific field that focuses on understanding the evolutionary relationships between living organisms. Specifically, it seeks to reconstruct the evolutionary history of these organisms and the existing relationships between them. This is done through the use of phylogenetic trees, which provide a graphical representation of the evolutionary processes that have shaped the relationships between different groups of organisms. In these trees, the leaves represent the different groups of organisms that exist today, while the root represents their common ancestor. The branches of the phylogenetic tree represent the evolutionary processes that have occurred over time. By analyzing the genetic data of different organisms, researchers can estimate the relationships between different taxa and construct accurate phylogenetic trees. However, constructing phylogenetic trees is not always a straightforward task. There are various factors that can introduce complexity into the process, including hybridization and lateral gene transfer. In order to overcome this challenge, researchers have developed a range of different models and methods for constructing phylogenetic trees and generalizing them to phylogenetic networks. One important aspect of phylogenetic reconstruction is the identification of phylogenetic invariants for different nucleotide substitution models. These invariants offer a valuable tool to distinguish phylogenetic trees and comprehend the evolutionary relationships among diverse organisms. As we will see, they can also be used for distinguising phylogenetic networks, which can represent evolutionary events that trees cannot. By identifying these invariants, researchers can gain a deeper insight into the complexities of evolutionary relationships, and thus provide a more accurate representation of the evolution of living organisms. |
