N2 - Nonlinear rhythmometry confirms a pattern of about 7 years, describing the number of births by birth year of quantum fathers reported by Verhulst and Onghena in 1996 and estimates the period to be 6.53 years with a 95% confidence interval overlapping 7 years. Other patterns of about 7 years are found in biology, as shown herein for the mean gonadal weight of an echinoderm (the purple sea urchin) and a mollusk (the black chiton). A number of periodic components with different frequencies, some shown to be genetically anchored, await applications in psychology as well as in other fields of medicine and biology.
