👉 The term "epizoic" refers to a group of organisms that share a common ancestor, but have diverged from each other in different ways. This can be due to a variety of factors such as environmental changes, genetic mutations, or even different forms of life (e.g., viruses). The term is often used in the context of evolution and biological classification, where it describes groups of organisms that are genetically related but have diverged from one another through various processes.
