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.
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.
5 Ιουλ 2016 · It is suggested that the evolution of the hominin lineage is consistent with a mosaic pattern of change. This article is part of the themed issue ‘Major transitions in human evolution’. 1. Introduction. Evolution—that is evolution simply as change through time—can be broken down into two elements.
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.
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".
human evolution (especially Jonathan Kingdon and Edward O. Wilson (pers. comms.)) pointed out to us that mosaics are a fairly obvious concept for any naturalist who works in a part of the world where vegetation is not found in large uniform blocks.
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.
