Abstract
Genomic sequentiation opens the possibility for searching genes related to diseases and behavior alterations. It should be interesting, using the genomic and proteomic tools, to investigate how patterns of behavior are inherited. Gene sequences and the structure and functions of the proteins confirm that we share the same molecules with the rest of the living organisms. These facts will change the vision that we have about us and other living creatures and should motivate to reflect about the relationship between bioethics and science.
