Resumen de Comienzo ontogénico del individuo humano desde su genoma
Diverse propositions about the ontogenetic origin of a live organism, specially human beings, are examined. Unambiguous and objective propositions about this origin are that a live organism is an ontogenetically programmed and integrated organisation, that the origin condition has the greater influence on other processes, that in pluricellular organisms, no organ or tissue can be considered critical to establish origins and that the origin must be established by endogenous elements. Several hypotheses about the origin of life are discarded. The integration between oocyte cytoplasm and the genetic material that it receives, that culminates in the first genome replication, is proposed as the process that gives origin to the individual. This process occurs in all living organisms. (Rev Méd Chile 2001; 129: 441-6)
