Introduction Common characteristics all Fungus share are that  their cells feature membrane-bound, complex  structures such as a nucleus, enclosed within  membrane  Pathogenic fungi are fungi that cause disease in  humans and other organisms  The Permo-Triassic Extinction, known as the Great  Dying, was responsible for the extinction of 90% of  marine life and 75% of terrestrial life.

Introduction Fungus is dangerous in the way it pushes other  organisms to the brink or completely to extinction  Scientists are studying fungi in hopes to gain a better  knowledge of its constant methods of surviving, for  example how they are able to infect the host  organism

Evolution Fungal phylogeny was  once based on  morphological  characteristics and  heterotrophic nutrition The new classification  is based on molecular  analysis of fungal DNA  and distinguishing  fungal characteristics  http://www.springerlink.com.ezproxy2.library.drexel.edu/content/vl13

Evolution New classification is based on molecular analysis of  fungi, and finding traits from the organisms’ life  cycles, structural anatomy, and biochemical pathways Examples of fungi characters include flagellation, cell  wall structure, and the site of meiosis to determine a  modern monophyletic classification
