Early embryological development can teach us about the unique and characteristic qualities of humans.

Can we give a scientific basis to the notion that humans have uniquely human features? Are the human mind and the human organism ‘nothing but’ another variation of animal life? Can the answers to these questions satisfy both heart and mind?

How these questions are answered depends on the scientific method we use: the current scientific method can teach us about biological facts; when we then proceed with and add the 4-step approach, a comparative approach, we may understand more about the meaning of these facts.

One result is, for example, that we understand more about the relationship between mind, behavior, and body shape.
