Detailed explanation-1: -Macroevolution: Large-scale evolution occurring over geologic time that results in the formation of new species and broader taxonomic groups.

Detailed explanation-2: -Speciation is the process by which one or more species1 arises from a common ancestor, and “macroevolution” refers to patterns and processes at and above the species level – or, transitions in higher taxa, such as new families, phyla, or genera.

Detailed explanation-3: -First published Mon Jun 3, 2019. Macroevolution refers (most of the time, in practice) to evolutionary patterns and processes above the species level. It is usually contrasted with microevolution, or evolutionary change within populations.

Detailed explanation-4: -Macroevolutionary processes, such as origins, diversifications, and extinctions, happen on a grand scale and take time-geologic time. To understand such processes requires historical evidence, for example, fossils dating back hundreds of millions of years, or slowly evolving molecular sequences.

Detailed explanation-5: -Microevolution happens on a small scale (within a single population), while macroevolution happens on a scale that transcends the boundaries of a single species.
