La regla de Rosa
La regla de Rosa, también conocida como la ley de la reducción progresiva de la variabilidad de Rosa, es una regla biológica que observa la tendencia a ir de la variación de caracteres en los representantes más primitivos de un grupo taxonómico o clade a un estado de caracteres fijo en los miembros más avanzados. Un ejemplo de la regla de Rosa es que el número de segmentos torácicos en adultos puede variar en las especies de trilobitas cambrianas, mientras que desde el Ordovícico el número de segmentos torácicos es constante en los géneros enteros, familias e incluso subordenes. Por lo tanto, se puede observar una tendencia a la disminución de la variación de rasgos entre individuos de un taxón a medida que el taxón se desarrolla a lo largo del tiempo evolutivo.

(Redirected from Rosa's Rule )
By the Ordovician , trilobites such as Dindymene didymograpti thoracic segments . Rosa's rule , also known as Rosa's law of progressive reduction of variability ,[ 1] biological rule that observes the tendency to go from character variation in more primitive representatives of a taxonomic group or clade to a fixed character state in more advanced members. An example of Rosa's rule is that the number of thoracic segments in adults (or holaspids ) may vary in Cambrian trilobite species, while from the Ordovician the number of thoracic segments is constant in entire genera, families, and even suborders.[ 2] Daniele Rosa .[ 3]
Rules
Allen's rule Shorter appendages in colder climates Bateson's rule Extra limbs mirror their neighbours Bergmann's rule Larger bodies in colder climates Cope's rule Bodies get larger over time Deep-sea gigantism Larger bodies in deep-sea animals Dollo's law Loss of complex traits is irreversible Eichler's rule Parasites co-vary with their hosts Emery's rule Insect social parasites are often in same genus as their hosts Fahrenholz's rule Host and parasite phylogenies become congruent Foster's rule (Insular gigantism , Insular dwarfism ) Small species get larger, large species smaller, after colonizing islands Gause's law Complete competitors cannot coexist Gloger's rule Lighter coloration in colder, drier climates Haldane's rule Hybrid sexes that are absent, rare, or sterile, are heterogamic Harrison's rule Parasites co-vary in size with their hosts Hamilton's rule Genes increase in frequency when relatedness of recipient to actor times benefit to recipient exceeds reproductive cost to actor Kleiber's law An animals metabolic rate decreases with its size Hennig's progression rule In cladistics, the most primitive species are found in earliest, central, part of group's area Jarman–Bell principle The correlation between the size of an animal and its diet quality; larger animals can consume lower quality diet Jordan's rule Inverse relationship between water temperature and no. of fin rays, vertebrae Lack's principle Birds lay only as many eggs as they can provide food for Rapoport's rule Latitudinal range increases with latitude Rensch's rule Sexual size dimorphism increases with size when males are larger, decreases with size when females are larger Rosa's rule Groups evolve from character variation in primitive species to a fixed character state in advanced ones Schmalhausen's law A population at limit of tolerance in one aspect is vulnerable to small differences in any other aspect Thayer's law The top of an animals coloration is darker than the bottom Thorson's rule Number of eggs of benthic marine invertebrates decreases with latitude Van Valen's law Probability of extinction of a group is constant over time von Baer's laws Embryos start from a common form and develop into increasingly specialised forms Williston's law Parts in an organism become reduced in number and specialized in function Related
