[MUSIC] [BIRD CHIRP] Take a perfectly good book and start changing letters, and it won’t take long before it’s unreadable. Information has been lost. Then how did evolution, through a similar process, morph the simplest life forms into the most complex? Evolution can create information. Many people think this is impossible, but there’s several ways we know it happens. When DNA is copied or shuffled to make sperm or eggs, genes or sets of genes can be duplicated. With an extra copy no longer constrained by natural selection, the duplicate is free to take on a new role. Nearly all flowering plants, and many grasses, have had their entire genome duplicated at least once. Organisms can also swap or steal genetic material. It’s most common in bacteria and other microbes, But, a good ...
