The concepts of niche conservatism and adaptive radiation have played central roles in the study of evolution and ecological diversification. What is the definition of diversification? Definition: Diversification is a growth strategy that capitalizes on market opportunities by allocating investment risk over different asset classes. Apart from the definitions by scholars like (Turner, 2005; Thompson & Strickland, 2006; Aggarwal & Samwick, 2003), Johnson et al. With respect to phenotypic evolution, the two processes may be seen as opposite ends of a spectrum; however, there is no straightforward method for the comparative analysis of trait evolution that will identify these contrasting scenarios. (2006) says it’s a collection of businesses under one corporate umbrella. Diversification is an asset allocation plan, which properly allocates assets among different types of investment. Alternative splicing and evolution: diversification, exon definition and function Hadas Keren, Galit Lev-Maor and Gil Ast Abstract | Over the past decade, it has been shown that alternative splicing (AS) is a major mechanism for the enhancement of transcriptome and proteome diversity, particularly in … Paleontologists observe that organisms have continuously changed since the Cambrian Period, more than 500 million years ago, from which abundant animal fossil remains are known. Evolution describes the cumulative changes that occur in the heritable characteristics of a population. Definition: Diversification can be understood as the corporate strategy that a company implements to increase the market share and sales volume by introducing new products in new markets or industry, which is distinct from its core business. diversification, and a new definition of the clade Linda A. Tsuji* and Johannes Mller Museum fr Naturkunde Berlin, 10115 Berlin, Germany. The export diversification and quality database was developed by IMF staff under an IMF-DFID research collaboration. Each species in the interaction applies selection pressure on the others. 2007). The Export Diversification Database has three main indicators: the Export Diversification Index, the Extensive Margin, and the Intensive Margin. Coevolution can lead to specialized relationships, such as between predator and prey. The concept of diversification is yet to be clearly defined and there is no consensus on the precise definition among researchers. We used trait-dependent diversification models to simultaneously model trait evolution and its impact on diversification (Maddison et al. Evolution - Evolution - Diversity and extinction: The current diversity of life is the balance between the species that have arisen through time and those that have become extinct. What Does Diversification Mean? In those models, species are characterized by an evolving trait, and their diversification follows a birth–death process in which speciation and extinction rates may depend on the trait state. E-mail: linda.tsuji@museum.hu-berlin.de Introduction The origin and radiation of amniotes in the Late Paleo-zoic represents the first colonization of land by fully ter- It can result in diversification within a species (microevolution) or diversification between species (macroevolution) Microevolution.

Coevolution, the process of reciprocal evolutionary change that occurs between pairs of species or among groups of species as they interact with one another.
