Does whales thinks like a human?

One type of Whales, the Humpback whales have a type of brain cell found only in humans, the great apes and other cetaceans such as dolphins. Whales are more intelligent than they have been given credit for, and suggests the basis for complex brains either evolved more than once or had gone unused by most species of animals. Researchers found spindle neurons in the same location in toothed whales with the largest brains. Toothed whales such as orcas are generally considered more intelligent than baleen whales such as humpbacks and blue whales, which filter water for their food. The humpbacks also had structures that resembled “islands” in the cerebral cortex, also seen in some other mammals.
