Mosaic evolution, the occurrence, within a given population of organisms, of different rates of evolutionary change in various body structures and functions. An example can be seen in the patterns of development of the different elephant species.
With mosaic evolution, a major morphological and behavioural transition of a trait (for instance, bipedalism in hominins) can occur through several adaptive solutions in different species and even genera, each being a different combination of primitive and derived sub-traits.

5 Ιουλ 2016 · It is not one phase of becoming human that represents a major transition, but the cumulative effect of them, the processes of mosaic evolution, and the very recent extinction of all other hominins that enhances the distinctiveness of humans.
Mosaic evolution, whereby transitional forms display a mixture of primitive and derived features, is nowadays recognized as a ubiquitous pattern of macroevolutionary change. Less known is that this expression was coined by Gavin de Beer in 1954.
