Nonsense.
An amoeba can adapt to its surroundings but i don't see it being 'creative'.
My computer can draw graphics autonomously (without me telling it what to do) and yet it never showed any creativity (unless you mean the artifacts from overheating

)
Indeed creativity is not
necessary for autonomy. My bad. Yet it is
usefull. And humans use it, so if machines are to do as good a job as humans, they might need to use it too.
No, you were probably correct in the first place. The amoeba was amazingly creative in that it did things that up until that point had never been done. Not creative by our elite human standards.
Nope.
Creativity implies intention.
I can assure you DNA molecules don't have intentions.
Intentions are a
result of brains and so cannot precede them.
Amoeba simply did what their genes were programmed to do with a healthy dose of randomness and those things they did turned out to make them better at survival and thereby making more of the genes that happen to survive etc.
Creativity, like all other abstract concepts that have no specific physical entity that they point to and predates them, is a human creation.
Well, not exactly.
I think that, for instance, all mammals posses a certain degree of creativity.
We as a species just happen to have a lot of it.
My point is just that creativity requires certain specific brain structures.
Without them an organism cannot be creative.
