Think of the coordination of a pod of dolphins or whales bubble-netting fish, that takes skill, coordination and tactics.Im not sure what your definition of evolved or unevolved is - every population of every species is evolving over time, Higher brain function is not a necessity of survival for many organisms, surviving in their environment is all that counts.......
Our great ape relatives can certainly think - they have complex social structures, can use a variety of tools and change their behaviour in response to the environment. Chimpanzees are much better at a range of complex skills than humans. Their vocalizations are not what we would recognise as speech but they convey complex messages to those who understand them.
Other animals including mammals and birds can think. Think of the coordination of a pod of dolphins or whales bubble-netting fish, that takes skill, coordination and tactics.

Apes vocalize and think. The great apes, as well as many sea mammals, exhibit sentience. Gorillas that learn sign language often create new words by combining others they haved learned. Coco, when given watermelon, combined the words water and fruit "waterfruit" to request it again.
Dolphin communication is incredibly complex and may even be transmitting imagery.
...but I'm guessing you don't really want a real answer...do you?
They can think, they just don't have the larynx to speak.
