Convergent evolution refers to the phenomenon where two different species evolve similar traits or characteristics due to environmental pressures and natural selection. These similarities may arise even though the species are not closely related genetically. Synonyms for the word "convergent evolution" include "parallel evolution," "homoplasy," or "convergency." The term "parallel evolution" refers to the evolution of similar traits in two different species that have a common ancestor. "Homoplasy" is a term used to describe similar traits that are not inherited from a common ancestor, but rather have independently evolved in different species. "Convergency" refers to the convergence of distinct species towards a common evolutionary path, leading to similar traits or adaptations.
