Fungi evolved far higher on the evolutionary ladder than did bacteria or viruses.  Their DNA is closer to human’s than are plant’s.  This makes human fungal infections more difficult to treat.  That said, fungi are Earth’s main decomposer and provide nutrition for humans.  We have proved that the Chinook and Cayuse, residents for 500x as long as pioneer presence in the NQ, can become extinct!  Might a fungus create an extinction of the human species?  A drug-resistant fungus known as Candida auris that is resistant to all three main classes of antifungals has been reported.  It may result from natural causes, or it may be the result of human action.  CRISPR gene engineering mail order tool kits are available via the Web to play with bacteria, viruses, fungi …  yeasts, molds, and mushrooms are like animals: they cannot make their own food.  They differ from plants and bacteria as their cell walls are made of chitin.  This substance, chitin, is also found in insects and crustaceans’ exoskeletons.  Fungi eating chitin is a suspected cause of Bee Colony Collapse Disorder (CCD), a bee colony disappearing, leaving behind a queen with plenty of food but no workers.  Bees feeding on pollen filled with fungicides, insecticides and other agriculture chemicals appear likely to be infected by Nosema ceranae, a parasitic microsporangium fungus associated with these widespread deaths. Hives of Western Honeybees infected with Nosema are wiped out within 8 days. Hive losses are currently 40% per year.
