reticulate evolution definition

Here, we will use a modified form of a definition originally proposed by Huson and Bryant Resembling or forming a net or network: reticulate veins of a leaf. Evolution, theory in biology postulating that the various types of plants, animals, and other living things on Earth have their origin in other preexisting types and that the distinguishable differences are due to modifications in successive generations. Reticulate Evolution "To the Grants, the whole tree of life now looks different from a year ago. Reticulate definition is - resembling a net or network; especially : having veins, fibers, or lines crossing. Reticulate evolution encompasses processes that conflict with traditional Tree of Life efforts. The theory of evolution is one of the fundamental keystones of modern biological theory.. reticulating synonyms, reticulating pronunciation, reticulating translation, English dictionary definition of reticulating. The set of young twigs and shoots they study seems to be growing together in some seasons, apart in others. Since several previous studies have demonstrated that introgressive hybridization has occurred among some species within Lepus, therefore it is possible that introgressive … Reticulate evolutionary processes, such as unequal crossing-over and gene conversion, are known to occur within specific duplicon families, but the broader contribution of these processes to the evolution of human duplications remains poorly characterized. Define reticulating. Reticulate evolution can be a major driver of diversification into new niches, especially in disturbed habitats and at the edges of ranges. The same forces that created these lines are moving them toward fusion and then back toward fission." Reticulate Evolution and Phylogenetic Networks 239 While the term “phylogenetic tree” is well defined (Chapter 5), the meaning of “phylogenetic network” is somewhat ambiguous, and in the literature there exist many different usages of the term. adj. Possible reticulate evolution in Sequoioideae. The diversity of the living world is … HGT has a profound impact on prokaryotic and eukaryotic evolution. 12 2. How to use reticulate in a sentence. 1. Reticulate evolution refers to origination of a taxon through merging of ancestor lineages. Interspecific hybridization may lead to the introgression of genes and genomes across species barriers and contribute to a reticulate evolutionary pattern and thus taxonomic uncertainties. Learn more. Within the gymnosperms however it is quite rare. Taking into consideration that mounting evidence for hybridization and polyploidy in eukaryotic taxa accumulates, it is essential to have methods to infer reticulate evolutionary histories. These processes, horizontal gene transfer (HGT), gene and whole-genome duplications through allopolyploidization, are some of the main driving forces for generating innovation and complexity. Reticulate evolution in plants has long been recognized, and recent genomic evidence from animals also indicates its widespread occurrence. Did You Know? Research on reticulate evolution today takes on inter- and transdisciplinary proportions and is able to unite distinct research fields ranging from microbiology and molecular genetics to evolutionary biology and the biomedical sciences. Industrial fermentation strains of yeast provide a window into these processes, but progress has been hampered by a limited understanding of the natural diversity and distribution of Saccharomyces species and populations. Polyploidy has come to be understood as quite common in plants—with estimates ranging from 47% to 100% of flowering plants and extant ferns having derived from ancient polyploidy. evolution meaning: 1. the way in which living things change and develop over millions of years: 2. a gradual process…. ; especially: having veins, fibers, or lines crossing of modern biological theory study seems be.
