Mosaic evolution (or modular evolution) is the concept, mainly from palaeontology, that evolutionary change takes place in some body parts or systems without simultaneous changes in other parts. [1] Another definition is the "evolution of characters at various rates both within and between species".
28 Μαΐ 2023 · Mosaic evolution plays a key role in macroevolution. Mosaic evolution brings stage by stage changes in different parts of organs. It sets a flexible framework within which different organs have to grow and develop in relation to other parts of an organism.
26 Δεκ 2017 · Here, we analyze mosaic evolution in the avian skull using high-dimensional 3D surface morphometric data across a broad phylogenetic sample encompassing nearly all extant families. We find that the avian cranium is highly modular, consisting of seven independently evolving anatomical regions.
14 Μαΐ 2018 · mosaic evolution The differential rates of development of various adaptive attributes within the same evolutionary lineage. For example, a particular taxon might show greatly different rates of change with respect to the leaves, shoots, and roots.
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.
