The baby validates his work. There is no altruism in this film. There is no loving of another because of one's admitted need for their love and enjoyment of their life. The flaw in the resolution begins with the need to see emotion and altruism as a female principle and aggression and narcissism as a male principle. This premise is established early in the film and inevitably leads to the narcissistic solution I have described.
Men create life without women.
Women can create life without men. Neither men nor women learn that the capacity for aggression and narcissism and the capacity for love and altruism exists in the other. At the end of the film, she sits across from Dr. Grant as they ride the helicopter home looking smugly upon her creation and he in turn looks upon his children who have proven how great and powerful a savior he is. Because the woman's effort is to preserve life, it is easy to miss the form of grandiosity and arrogance that is embodied in her smug attitude towards Dr. Grant. She, however, never interacts with the children.
