Sordaria fimicola and Genetic Diversity 23 October 2013 Sordaria fimicola and Crossover Frequencies in relation to Evolution Canyon Introduction Evolution Canyon is an important natural phenomenon‚ which is widely studied for its benefit in helping recreate evolution in a short period of time. It helps us visualize evolution‚ a process that takes place in the span of millions of years‚ because the animals on the canyon go through “evolution” in a very short‚ examinable time. There are two types

The Discovery and Research of Penicillin Alexander Fleming’s discovery of penicillin while examining a stray mold in his London laboratory in 1928‚ and its eventual development by Howard Florey and Ernst Chain at Oxford University‚ created a major break through to another world of antibiotics and medicine. Antibiotics like penicillin have become the most important family of drugs of this era. During the 1940’s (World War 2) penicillin became a life saving drug to thousands of soldier’s‚ it also
