What is "Mind?"

Exactly where on the tree of life does intelligence emerge? Or if you prefer, Sentience?

Are there other species, or is it only humans?

A very general mental capability that, among other things, involves the ability to reason, plan, solve problems, think abstractly, comprehend complex ideas, learn quickly and learn from experience. It is not merely book learning, a narrow academic skill, or test-taking smarts. Rather, it reflects a broader and deeper capability for comprehending our surroundings—"catching on," "making sense" of things, or "figuring out" what to do.[7]

Encephalization quotient (EQ), or encephalization level, is a measure of relative brain size defined as the ratio between actual brain mass and predicted brain mass for an animal of a given size, which is hypothesized to be a

Quotation

Alfred Binet Judgment, otherwise called "good sense," "practical sense," "initiative," the faculty of adapting one's self to circumstances ... auto-critique.[9]
David Wechsler The aggregate or global capacity of the individual to act purposefully, to think rationally, and to deal effectively with his environment.[10]
Lloyd Humphreys "...the resultant of the process of acquiring, storing in memory, retrieving, combining, comparing, and using in new contexts information and conceptual skills."[11]
Cyril Burt Innate general cognitive ability[12]
Howard Gardner To my mind, a human intellectual competence must entail a set of skills of problem solving — enabling the individual to resolve genuine problems or difficulties that he or she encounters and, when appropriate, to create an effective product — and must also entail the potential for finding or creating problems — and thereby laying the groundwork for the acquisition of new knowledge.[13]
Linda Gottfredson The ability to deal with cognitive complexity.[14]
Sternberg & Salter Goal-directed adaptive behavior.[15]
Reuven Feuerstein The theory of Structural Cognitive Modifiability describes intelligence as "the unique propensity of human beings to change or modify the structure of their cognitive functioning to adapt to the changing demands of a life situation."[16]
Charles Spearman "...all branches of intellectual activity have in common one fundamental function, whereas the remaining or specific elements of the activity seem in every case to be wholly different from that in all the others."[17]
Legg & Hutter A synthesis of 70+ definitions from psychology, philosophy, and AI researchers: "Intelligence measures an agent’s ability to achieve goals in a wide range of environments,"[5] which has been mathematically formalized.[18]

I think I’ll respond to some of the things he said to me, but I think I’ll do so off-line with him.

There is nothing to say, nothing to do, no where to go, and even nothing to be. The only real self is no-self.
