The question is worded in a way that does not make much sense. There are, in fact, animals with NO intelligence. For example, a sponge is technically an animal, although they completely lack brains, and nerves for that matter.
A more reasonable question might be "which vertebrate has the least intelligence," because all vertebrates have a measurable intelligence. You can't really figure out how much an insect can learn on its own.
It you mean lacking in intelligence, then they are not dumb, they have intelligence according to their local needs. If you mean refraining from any or much speech, then Yaks 'grunt'

There are a number of animals that are known to be solitary animals, and thus, are pretty disloyal. However, the animal that is considered to be the least loyal would be the Tasmanian devil.
My vote goes to tuna

Is animal intelligence evolving faster than in the past.
Yes it is known to be not to but ask a proffesianal
I think it would be easier to answer if your question was "What animals have characteristics of human intelligence?" It is impossible for any animal to have human intelligence.
