We know very well that we have ancestors. But our ancestors are not only human. We have animal ancestors, we have plant ancestors, and we have mineral ancestors. Our human ancestors are still very young. We appeared on Earth very late in the history of life. Our animal ancestors are still there in us. The reptile, the fish, and the ape are still in us. Not only were they part of us in the past, but we continue to have them within us in the present moment. Just look deeply into our cells; we see that we are the whole history of life.
