What Does Diversification Mean? Diversification is an asset allocation plan, which properly allocates assets among different types of investment.

Historical changes in diversity: Many events have left their marks on the diversity of life on Earth, pruning or growing the tree of life, but a few stand out as unusually important: Coevolution, the process of reciprocal evolutionary change that occurs between pairs of species or among groups of species as they interact with one another. 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. The export diversification and quality database was developed by IMF staff under an IMF-DFID research collaboration. We used trait-dependent diversification models to simultaneously model trait evolution and its impact on diversification (Maddison et al. What is the definition of diversification? The Export Diversification Database has three main indicators: the Export Diversification Index, the Extensive Margin, and the Intensive Margin. Definition: Diversification is a growth strategy that capitalizes on market opportunities by allocating investment risk over different asset classes. Higher values for the all three indices indicate lower diversification. Coevolution can lead to specialized relationships, such as between predator and prey. Apart from the definitions by scholars like (Turner, 2005; Thompson & Strickland, 2006; Aggarwal & Samwick, 2003), Johnson et al. The rapid diversification of mammals shown below may constitute an adaptive radiation. 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. 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 … (2006) says it’s a collection of businesses under one corporate umbrella. 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. 2007). The concept of diversification is yet to be clearly defined and there is no consensus on the precise definition among researchers. The concepts of niche conservatism and adaptive radiation have played central roles in the study of evolution and ecological diversification. diversification, and a new definition of the clade Linda A. Tsuji* and Johannes Mller Museum fr Naturkunde Berlin, 10115 Berlin, Germany. It can result in diversification within a species (microevolution) or diversification between species (macroevolution) Microevolution. Evolution describes the cumulative changes that occur in the heritable characteristics of a population. 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.
