Mind, consciousness and intelligence are hard. From a scientific perspective, all three are products of the brain. There is matter and nothing else. The question then is to figure out how the brain does it: how we can ask profound questions and write essays about them while dogs and chimps can’t, even though they are arguably intelligent. There are levels of intelligence, levels of consciousness and levels of mindfulness. So, one of the questions about origin of mind is how it evolved to the level we see today.
