Evolutionary change on a grand scale, encompassing the origin of novel designs, evolutionary trends, adaptive radiation, and mass extinction.

A vague term, usually meaning the evolution of substantial phenotypic changes, usually great enough to place the changed lineage and its descendants in a distinct genus or higher taxon. © 200 [..]

Evolutionary change on a grand scale, encompassing the origin of novel designs, evolutionary trends, adaptive radiation, and mass extinction. macrofauna

There is a close association between the great events of macroevolution and the appearance of organic codes. The origin of the genetic code, for example, gave origin to biological specificity, the mos [..]

Evolutionary change at or above the species level.

Evolutionary changes at the level of species or higher taxonomic groups.  Macroevolution occurs on geologic time scales, to be contrasted with microevolution, which occurs on short time scales.

(n) evolution on a large scale extending over geologic era and resulting in the formation of new taxonomic groups

Evolution at or above the species level, i.e., of species or clades. See Punctuated Equilibrium.

Macroevolution is evolution on the grand scale: the term refers to events above the species level; the origin of a new higher group, such as the mammals, would be an example of a macroevolutionary eve [..]

Evolution above the species level; the evolution of higher taxa and the processes that result from differences in species survivorship or rates of speciation.

This means evolution at the level of a species, or higher. For example, the evolution of land animals into whales would be macroevolution. A species of moth turning black is microevolution

A vague term, usually meaning the evolution of substantial phenotypic changes, usually great enough to place the changed lineage and its descendants in a distinct genus or higher taxon. Cf. microevolution.

The evolution of species or higher taxonomic groups, such as genera, families, or classes. Compare with microevolution.
