In this article, we will explore the fascinating world of Phylogenesis and everything this concept or person has to offer. From its historical origins to its relevance today, Phylogenesis has played a fundamental role in various aspects of society. Throughout these pages, we will analyze its impact on culture, technology, politics and many other areas. Additionally, we will delve into its different facets, examining how Phylogenesis has evolved over time and how it continues to influence our lives. Get ready to immerse yourself in a journey of discovery through this exciting topic, in which we will explore its meaning, its implications and its relevance in the contemporary world.
Phylogenesis (from Greek φῦλον phylon "tribe" + γένεσις genesis "origin") is the biological process by which a taxon (of any rank) appears. The science that studies these processes is called phylogenetics.
These terms may be confused with the term phylogenetics, the application of molecular - analytical methods (i.e. molecular biology and genomics), in the explanation of phylogeny and its research.
Phylogenetic relationships are discovered through phylogenetic inference methods that evaluate observed heritable traits, such as DNA sequences or overall morpho-anatomical, ethological, and other characteristics.
The result of these analyses is a phylogeny (also known as a phylogenetic tree) – a diagrammatic hypothesis about the history of the evolutionary relationships of a group of organisms. Phylogenetic analyses have become central to understanding biodiversity, evolution, ecological genetics and genomes.
Cladistics (Greek κλάδος, klados, i.e. "branch") is an approach to biological classification in which organisms are categorized based on shared, derived characteristics that can be traced to a group's most recent common ancestor and are not present in more distant ancestors. Therefore, members of a group are assumed to share a common history and are considered to be closely related.
The cladistic method interprets each character state transformation implied by the distribution of shared character states among taxa (or other terminals) as a potential piece of evidence for grouping. The outcome of a cladistic analysis is a cladogram – a tree-shaped diagram (dendrogram) that is interpreted to represent the best hypothesis of phylogenetic relationships.
Although traditionally such cladograms were generated largely on the basis of morphological characteristics calculated by hand, genetic sequencing data and computational phylogenetics are now commonly used and the parsimony criterion has been abandoned by many phylogeneticists in favor of more "sophisticated" (but less parsimonious) evolutionary models of character state transformation.
Taxonomy (Greek language τάξις, taxis = 'order', 'arrangement' + νόμος, nomos = 'law' or 'science') is the classification, identification and naming of organisms. It is usually richly informed by phylogenetics, but remains a methodologically and logically distinct discipline. The degree to which taxonomies depend on phylogenies (or classification depends on evolutionary development) differs depending on the school of taxonomy: phenetics ignores phylogeny altogether, trying to represent the similarity between organisms instead; cladistics (phylogenetic systematics) tries to reproduce phylogeny in its classification
An extension of phylogenesis to the cellular level by Jean-Jacques Kupiec is known as Ontophylogenesis
Phylogenetics is the branch of life science concerned with the analysis of molecular sequencing data to study evolutionary relationships among groups of organisms.
