👉 Phylogenesis refers to the process of studying the evolutionary relationships between different species or groups of organisms. It involves identifying the ancestors and descendants of a particular species, as well as analyzing how these relationships have evolved over time. This can be done through various methods such as DNA sequencing, fossil records, and comparative genetic analysis. The goal is to understand the origins and development of life on Earth, and to gain insights into the evolution of different species and their roles in ecosystems.
