Mutations and repairs
• Point mutation -> letter substitution• Insertion mutation -> letter insertion• Deletion mutation -> letter deletion
• Repair -> spellcheck and replace “broken” words with best guess at correct word (sometimes you get a favorable mutation)
Parameters
• Do nothing rate• Point mutation rate• Insertion rate• Deletion rate
• Number of generations
Examples
• From so simple a beginning endless forms most beautiful and most wonderful have been, and are being, evolved.
• Fro simple beginning endlessness Dost beautiful and Yost Wonderful been and bing evolved
• Simple beginning endlessness Dost Beautiful Wonderful beebread evolved

Examples
• I love fools' experiments. I am always making them.
• lovelinesses allay marring Oh
• lonelinesses Earring
Lessons
• Mutations often kill off species (words)• Having an insertion or deletion rate too high very rapidly
kills off species (words)• There are some bizarre words in the English language
