What is basic instinct?
We normally use this term for animal and human. However we know plants have basic instinct to live and proliferate. Plants have no brain but they learn and have memories.
How can we describe physarum polycephalum? We know that it can solve problems which means it has intelligence. If something has ability to solve problems which means it has ability to remember. If it has ability to remember than it has memory capacity.
Also it needs and searches for food. Perhaps it sounds very classical for any species. However it means it has basic instinct to live and proliferate.
At this point, if something has basic instinct, intelligence, learning and problem solving capacity than how can we describe it?
