> Some species also have complex features, such as cells organized into structures resembling muscles for movement, for example. She just doesn’t find it plausible that such complexity arose from a cancer. Wouldn't that (theoretically) be be easier for cancer cells? The article doesn't state if these muscles came from "new" genes that were evolved for this or if they reactivated pre-existing genes from more complex ancestors, but the latter seems like a significantly smaller evolutionary leap than the former, and cancer cells would be in the unique position to be able to do that.
