The patato family island kills a million people in a mass imigration. The patatoes were destroyed by L. Calls by the water infested 1. Now we know exactly which steam of the water did the dirty work. Researchers analyzed 2 the dry patato leaves well over a century old from Ireland as well as y epic 3 North America. They were able to sequence the d of 11 different strands 4 of f and none to compare these oldest specimens 5 to 15 modern ones. The conclusion a strange c one is responsible for the Iresh great famine. The work is in the general e-life. A strange code US one has previously 6 been adopted for the cold bread and two s are closedly related. E one held ways during the 19th century. But with the introduction of new kinds of potatoes in the 20th century, US one began to dominate. Similar work with other preserved plant specimens could help trace the evolutionary 7 history about the p and assist the on-going effort to keep our stable crops disease free.
