We are all connected in many ways. On a physical level, humans share 99.9% of the same DNA with each other. This still leaves approximately 3 million differences between yourself and
other humans. However, it still means you are only one tenth of one percent different than other people.
Now, if we look at it with regard to actual relationships, consider that each person has 4,096 10th -Great grandparents. Each of those ancestors had children who in turn had children. As a result, you have thousands upon thousands of cousins in those generations, which means that you have a good chance of crossing paths every day with cousins without any clue that you are related.
If research was performed and all the records over the generations were found, you would likely find out that you are related to the clerk at the grocery store, your doctor, and your neighbor. Some of these people may share your opinions and perspectives, while others do not. Similarly, these people may have various skin colors, ethnic backgrounds, and life situations.
As you go through your day, consider that each person you meet might be a not so distant relative. Ask yourself if finding out that they were related would change your opinion of them. What changes? What stays the same?
