Artificial intelligence

We think of artificial intelligence as something created through the use of electronics and complex programming. A product of the calculating machines we create. However, looking at the latest psychological and neurological research, an argument could be made that human intelligence is also a kind of artificial intelligence. A product of the electronic calculating machines that nature and evolution have created.

Is human intelligence a kind of artificial intelligence?
If not, then what makes it different from other kinds of artificial intelligence?

If so, then is there a deeper, non-artificial kind of intelligence, and what is it, and where does it come from?
