Lots of talk about bacteria here.
I believe these buggers are considered to be the oldest life form in our planet’s history. We’re told they popped onto the scene (some say by “self-assembling”) about 3 billion years ago. And, of course, they’re still with us today.
Why, after 3 billion years of mutating (according to you, even “intentionally” mutating (who knew?)) are bacteria still just… bacteria?
Why such a perfect record of RESISTANCE TO SIGNIFICANT CHANGE, when evolutionists say virtually all OTHER current life forms are the result of mind-boggling transformations (for example, and with little exaggeration, “Barry Bonds’ ancestor is a bumble bee”)?
Because the are successful! A lot more of them than there are humans and we spend billions of dollars trying to get rid of them while their natural defenses derived from evolution thwart our most advanced technology!
Bacteria are everywhere, and are highly successful and highly adaptable. Most likely our mitochondria and plants chloroplasts have bacterial ancestry, so they are inside us and have evolved with us.
Bacteria are in no way ‘resistant to change’, significant or otherwise.
Now how about addressing the question?
Why would a bacteria as part of its stress response increase its mutation rate?
