Lucien Cuénot
Lucien Claude Marie Julien Cuénot (; 21 October 1866 – 7 January 1951) was a French biologist. In the first half of the 20th century, Mendelism was not a popular subject among French biologists. Cuénot defied popular opinion and shirked the “pseudo-sciences” as he called them. Upon the rediscovery of Mendel's work by Correns, De Vries, and Tschermak, Cuénot proved that Mendelism applied to animals as well as plants. Cuénot's experiments Cuénot spent two years working on mice and came to the conclusion that three “mnemons” (genes) are responsible for the production of one “chromogen” or pigment and two “distases” enzymes. The pigment (if present) is acted upon by the enzymes to produce black or yellow colour. If no pigment is present the result is an albino mouse. Cuénot studied the offspring of various crosses between mice and concluded that these “mnemons” or genes were inherited in a Mendelian fashion. Subsequently, Cuénot was the first person to des ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Tardigrade
Tardigrades (), known colloquially as water bears or moss piglets, are a phylum of eight-legged segmented micro-animals. They were first described by the German zoologist Johann August Ephraim Goeze in 1773, who called them Kleiner Wasserbär ("little water bear"). In 1777, the Italian biologist Lazzaro Spallanzani named them Tardigrada (), which means "slow steppers". They have been found in diverse regions of Earth's biospheremountaintops, the deep sea, tropical rainforests, and the Antarctic. Tardigrades are among the most resilient animals known, with individual species able to survive extreme conditions – such as exposure to extreme temperatures, extreme pressures (both high and low), air deprivation, radiation, dehydration, and starvation – that would quickly kill most other known forms of life. Tardigrades have survived exposure to outer space. There are about 1,300 known species in the phylum Tardigrada, a part of the superphylum Ecdysozoa consisting of animals th ...

Echiniscidae
The Echiniscidae are a family of tardigrades, a phylum of water-dwelling, eight-legged, segmented micro-animals. It is one of the four families in the order Echiniscoidea.Echiniscidae The family was named by Gustav Thulin in 1928.Thulin, ''Über die Phylogenie und das System der Tardigraden'' (''On the Phylogeny and the System of Tardigrade'').

University Of Modena And Reggio Emilia
The University of Modena and Reggio Emilia ( it, Università degli Studi di Modena e Reggio Emilia), located in Modena and Reggio Emilia, Emilia-Romagna, Italy, is one of the oldest universities in Italy, founded in 1175, with a population of 20,000 students. The medieval university disappeared by 1338 and was replaced by "three public lectureships" which did not award degrees and were suspended in the 1590s "for lack of money". The university was not reestablished in Modena until the 1680s and did not receive an imperial charter until 1685.Quoted from: Grenler, Paul F. The Universities of the Italian Renaissance Johns Hopkins University Press, 2004. Page 137. Some famous students who attended the university include Ludovico Antonio Muratori, a noted Italian historian and scholar who graduated in 1694, the playwright Carlo Goldoni in the 17th century and, in the last century, Sandro Pertini, who became President of the Italian Republic.
