Parallel evolution is a fascinating concept that describes how different species can evolve similar traits independently of each other. There are several synonyms that are used to describe this phenomenon, such as convergent evolution, homoplasy, and adaptive radiation. Convergent evolution refers to the evolution of similar traits in different species that are not closely related. Homoplasy is used to describe the appearance of similar traits in two or more unrelated species. Adaptive radiation is the process of species diversification into multiple forms, each adapted to a specific environment or niche. These synonyms are key terms used in biology to describe the complex and dynamic process of evolution.
