What is the smallest or most specific level of organization organization you and your neighbors all have in common

The cell

Explanation:

The smallest or most specific level of organization that all living organisms (including myself and my neighbors) have in common is the cell.

This is in accordance with the cell theory which has three basic components, including:

1. The cell is the basic unit of life

2. All living organisms are made up cells

3. Cells arose from pre-exsiting cells.

Other levels of organisation include tissues which are group of cells specialized for a certain function, organs which are group of tissues serving similar function, and systems which are group of organs working together as a unit.
