Document Summary
Technology advancement =>very easy to spread virus around the globe. Viruses are everywhere, they infect all living things. Ingest viruses daily, ie insect viruses on vegetables. Wasps lay eggs inside a living insect larva=>have integrated polydna viral genome and would deposit polydnavirus virion into the larva when she deposit the eggs=>larva innate system. D. lanuginosum is a plant that grows at over 50 degrees=>cannot grow in hot environment infected by a fungus which cannot grow in hot enviroment unless infected by cthtv virus. A potyvirus thats elongated in shape and affects pigment synthesis=>results in broken tulips suppresed by virion. =genome is key (nothing will ever happen w/out it) =no virus can translate proteins from mrna on their own. Have existed for a long time (in the dinosaur age) Molecular clock sequencing=extract genome and figure out rate of mutation =>allowed for affirmation. Herpes: documented in ancient greece and romans (banned kissing in public to prevent transmission)
