Darwin-L was established to promote the reintegration of a range of fields all of which are concerned with reconstructing the past from evidence in the present, and to encourage communication among scholars, scientists, and researchers in these fields. The group had more than 600 members from 35 countries, and produced a consistently high level of discussion over its several years of operation. Darwin-L was not restricted to evolutionary biology nor to the work of Charles Darwin, but instead addressed the entire range of historical sciences from an explicitly comparative perspective, including evolutionary biology, historical linguistics, textual transmission and stemmatics, historical geology, systematics and phylogeny, archeology, paleontology, cosmology, historical geography, historical anthropology, and related “ palaetiological ” fields.

Un Gene- Un Enzima Di Sara Bancalari - Andrea Bertelà - Sara Bianchi Edoardo Rossi- Francesco Strà 1) Introduzione 2) L'ESPERIMENTO DI BEADLE E TATUM 3) LE CONSEGUENZE Così le ricerche di questo tipo, iniziate da Beadle, e oggi largamente coltivate, si riesce a stabilire con esattezza la reazione chimica che è controllata ciascun gene. E poiché non poche reazioni biochimiche sono comuni a molti organismi compresi quelli superiori si possono fare per questa via ulteriori progressi nella conoscenza dell'intera natura delle azioni geniche.Si noti poi che questi studi hanno grande importanza pratica per le industrie che si valgono dell'opera dei microrganismi. 4) CONIDI, LE SAPORE, E I CORPI FRUTTIFERI 5) TATUM E BEADLE TATUM Tatum, Edward Lawrie (Boulder 1909 - New York 1975), biochimico e genetista statunitense, ebbe incarichi accademici alla Stanford University di Palo Alto (1937-1945), alla Yale University di New Haven (1945-1948) e dal 1957 alla Rockefeller University di New York. Insieme a George Wells Beadle studiò la trasmissione dei caratteri ereditari nella muffa del pane e dimostrò che tutti gli enzimi vengono fabbricati a livello cellulare secondo le istruzioni contenute in alcuni specifici geni. Dunque, i processi biochimici controllati dagli enzimi in ultima analisi sono diretti a livello genetico. Per questi importanti risultati, nel 1958 Beadle e Tatum condivisero il premio Nobel per la fisiologia e la medicina con il genetista Joshua Lederberg. BEADLE Beadle, George Wells (Wahoo, Nebraska 1903 - Pomona, California 1989), biologo statunitense, celebre per gli studi pionieristici nel campo della genetica di funghi e lieviti. Professore di genetica a Harvard e a Stanford, fu successivamente direttore della divisione di biologia del California Institute of Technology di Pasadena e rettore dell'Università di Chicago. Nel 1958 condivise il premio Nobel per la fisiologia o la medicina con Edward Lawrie Tatum e Joshua Lederberg, in riconoscimento degli studi sul ruolo dei geni nella biosintesi degli enzimi. Scrisse Genetics and Modern Biology (1963) e, con la moglie Muriel Beadle, The Language of Life (1966).

Joshua Lederberg Pioneer of microbial genetics: Joshua Lederberg (1925-) by King-Thom Chung, Department of Biology, The University of Memphis Joshua Lederberg was awarded the 1958 Nobel Prize in medicine and physiology for his discovery of "sexual recombination" in bacteria (bacterial conjugation). This award was shared with Drs. George Wells Beadle (1903-1989) (1) and Edward Lawrie Tatum (1909-1975) (3). Conjugation is mediated by the presence of the F+ factor (fertility factor or plasmid) and requires cell to cell contact. The plasmid can reside inside the donor bacterium as an extrachromosomal element with its own origin of replication or it can be integrated into the bacterial chromosome. When integrated in the chromosome, replicative transfer begins within the F plasmid region at the oriT region and continues into the chromosomal region. Thus the chromosomal genes as well as F plasmid genes are transferred to the recipient cell during conjugation. Via a process of recombination ( Hfr and coined the term plasmid in 1950 to describe extrachromosomal genetic elements. However, the term was not widely accepted until the 1970s when bacterial drug resistance was shown to be mediated by self-transmissible plasmids and became a major medical problem.
