Nexilist Notebook

I recently read an article about potential relative influence of the father’s genes versus the mother’s genes on a developing embryo.

The theory held that the best outcome from the father’s point of view would be for the child to be as big as possible at birth to give it the best survival chance. The child’s personality should be demanding of the mother’s time and energy and not particular concerned with other children of the mother because they might not have the same father.

On the other hand, the mother’s best outcome would be for a lower birthweight baby which would have made less demands on the mother physically during the pregnancy. After birth the child should be less demanding on the mother’s time and energy and more sensitive to the needs of other children because they all have the same mother.

Taken to the extreme, the predominance of the father’s genes could potentially lead to autistic individuals who are oblivious to the social cues that signal needs and concerns of other. The extreme result of the mother’s genes could be schizophrenia where great sensitivity to the world overwhelms the individual.

I was fascinated by this conjuction of genetics, embryology, physiology, physchology, sociology and pathology.
