macroevolution
This term is used primarily in biological and paleontological discourse to distinguish large-scale evolutionary patterns from microevolution, which refers to small-scale changes within a single population. It carries a technical, academic register and is typically employed when discussing the origin of new species, genera, or higher taxonomic ranks.
Because it describes a broad biological process or a field of study, it is treated as an uncountable noun. It does not typically take a plural form in scientific literature, as it refers to the phenomenon of large-scale change rather than individual instances of change.
