This statement alone, would get this guy an “F” in any freshman biology course. Why do these people continue to play “dress up” as scientists? I know, they hope to save us, but there are many of us that are already there. It makes it terribly embarrassing for educated people (that are already saved, thank you very much) to have to make excuses for the logically challenged.
Before writing this stuff, it might be best to go back and review some freshman life science. Even if you've never attended college, these texts can be obtained at a campus bookstore at very reasonable cost if they are used. Failing that, perhaps simply going to a library and reading would assist your writing efforts, but do it BEFORE publishing. It would certainly improve your credibility as a scientific writer, which this author seems to be desperately seeking.
How is that wrong?
Aren’t all cancers and even benign tumors a result of mutation?
If so that would mean that mutations are visible within a single human lifetime.
