term paraphyly was first used by the German biologist and zoologist, will Henning in the early 1960s.<\/strong> Paraphyletic groups are beneficial in analyzing significant traits causing a subclade to take an <a href=\"https:\/\/microbenotes.com\/divergent-evolution\/\" data-type=\"post\" data-id=\"30055\">evolutionary divergent trait<\/a>. <strong>A paraphyletic group is a collection of organisms based on ancestral similarities as opposed to similarities among the individual group.<\/strong> The use of paraphyletic groups in cladistic taxonomy is only applied when the application of paraphyletic taxon is reasonable for taxonomic study and when incorporating comprehensive classification of the extinct groups because every species originated from the parts of another species.\u00a0<\/p>\n\n\n\n<p>We can look at the class Reptilia as a paraphyletic group because it excludes its two descendant groups, the class Mammalia and class Aves.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"cladistic-classification-neglects-paraphyly\"><\/span><strong>Cladistic Classification Neglects Paraphyly<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Cladistics does not allow reference of paraphyletic assemblage as \u2018groups\u2019 because they present non-evolutionary events, and the character traits derived from the common ancestors are mere inferences and not observations. Paraphyletic groups also appear problematic in taxonomic studies as they do not precisely distinguish between phylogenetic relationships, character traits, and extinction among species. Hence paraphyletic classifications are sometimes ruled out due to the rise of the clade system of classification.\u00a0<\/p>\n\n\n\n<p>The only negative aspect of using the cladistic approach is the disregard for evolutionary data in constructing branching patterns. Cladistic principles impose on a restrictive hypothesis, with data from synapomorphy being given importance while data from autapomorphies are discarded as non-informative.\u00a0<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"criteria-for-paraphyletic-classification\"><\/span><strong>Criteria for Paraphyletic Classification<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>To establish a paraphyletic group two things must be kept in mind which include<strong> the evolutionary significance and the construction of formal classifications.<\/strong> The recognition of evolutionary patterns is necessary to allow discrimination of paraphyletic ones from the polyphyletic category. Hence, establishing detailed criteria for formal classification is required. The following procedural steps must be applied for appropriate adherence to evolutionary classification principles.<\/p>\n\n\n\n<ul>\n<li><strong>Reconstruction of phylogenetic relationships<\/strong> using appropriate markers such as molecular, morphological, etc, and employing various analytical tools. For instance, distinguishing between paraphyletic and holophyletic species is seen as an acceptable criterion for classification due to their emphasis on the common ancestry.<\/li>\n\n\n\n<li><strong>Using phenotypic characters<\/strong> and their combinations from the observation of monophyletic and paraphyletic species. Combining phenotypic characters with common descent helps in distinguishing similarities arising from convergent or parallel evolution as observed in polyphyly.<\/li>\n\n\n\n<li><strong>Using patrocladistic methods<\/strong> to measure the degree of genetic and morphological divergence is a helpful criterion that excludes overestimation of isolated characters and subjective judgement.&nbsp;<\/li>\n\n\n\n<li><strong>Checking for meaningful evolutionary trait<\/strong> combinations of paraphyletic groups with emphasis on structure and its function plays a significant role in evolutionary success.<\/li>\n\n\n\n<li>Paraphyletic status should be applied as features of taxa that describe the evolutionary status of the group rather than a criterion for acceptance in classification.<\/li>\n\n\n\n<li>At last, <strong>choosing an appropriate rank<\/strong> as hierarchical systems help in gaining essential information on storage and retrieval and is beneficial for effective communication.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"examples-of-paraphyletic\"><\/span><strong>Examples of Paraphyletic<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<ul>\n<li><strong>Prokaryotes<\/strong> are one of the paraphyletic groupings as it excludes the eukaryotes being a distant group. This distinction was given by the french biologist Edouard Chatton in 1937.&nbsp;<\/li>\n\n\n\n<li>In the plant kingdom of classification, <strong>dicotyledons<\/strong> are referred to as a paraphyletic group which excludes the monocotyledons. Phylogenetic studies have shown that monocots are developed from the dicot ancestor, thus excluding monocots from dicots making it a paraphyletic group.<\/li>\n\n\n\n<li>In the animal kingdom, the <strong>order Artiodactyla<\/strong> (animals with even-toed ungulates like camels, pigs, hippopotamuses, etc.) is considered a paraphyletic group as it does not include Cetaceans (dolphins, whales, etc).&nbsp;<\/li>\n\n\n\n<li><strong>Bony fishes (Osteichthyes)<\/strong> can be referred to as paraphyletic when ray-finned fishes (Actinopterygii) and lungfishes (Sarcoptrygii) are only included in the group.<\/li>\n\n\n\n<li>The \u2018<strong>wasps<\/strong>\u2019 are put into the paraphyletic category which includes narrow-waisted organisms from the Apocrita superorder without including families of ants and bees.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"paraphyly-in-species\"><\/span><strong>Paraphyly in Species<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Paraphyly is a common event in speciation, where a mother species (paraspecies) gives rise to daughter species without itself becoming extinct. Research has shown that <strong>around 20% of animal species and 20-50 % of plant species are considered to be paraphyletic<\/strong>. Some examples include:&nbsp;<\/p>\n\n\n\n<ul>\n<li><strong><em>Daviesia ulicifolia<\/em><\/strong><em> <\/em>&#8211; It is a complex plant species belonging to the Fabaceae family under the division of Mirbelieae.
