IMO all life is intelligent in some way or form. Evolution itself is even intelligent in that it’s a learning system that adapts and solves problems.
It seems evolution is emergent given the physical ingredients and laws of nature, which points to some kind of inherent intelligence in the fabric of all stuff. By observing it for long enough, it becomes apparent that the stuff is behaving in a way that can be described as evolution (this is not some kind of appeal to intelligent design).
To whatever extent evolution is "intelligent" or "learning and solving problems", it is the underlying primordial stuff of existence at play. Thinking about this always blows my mind.
