There is an interesting popular book on Ethology by Frans De Waal. “Are we smart enough to know how smart animals are?” https://www.amazon.com/Are-Smart-Enough-Know-Animals/dp/0393246183 https://www.amazon.com/Are-Smart-Enough-Know-Animals/dp/0393... Here is a great review of this book http://www.theatlantic.com/magazine/archive/2016/05/how-animals-think/476364/?single_page=true http://www.theatlantic.com/magazine/archive/2016/05/how-anim... the passage that got me hooked: “a better way to think about other creatures would be to ask ourselves how different species have developed different kinds of minds to solve different adaptive problems. Children and chimps and crows and octopuses are ultimately so interesting not because they are mini-mes, but because they are aliens—not because they are smart like us, but because they are smart in ways we haven’t even considered" for example different species have different approaches to problem solving: Chimpanzees try to comprehend/model a problem while Monkeys are solving tool building problems by trial and error (that's from the book)
