CHAPTER IX. 



DUAL PARENTAGE. 



DUAL PARENTAGE. Or, the factor of heredity 

 resulting from the combination of nationalities 

 and families; from bi-sexual parentage and the 

 union and interblending of the physical and men- 

 tal qualities of parents in offspring. 



In the evolution of all forms of life the crossing 

 and consequent combining of the various' classes ^^ Parentage 

 and the uniting of the qualities of two parents in and Evolution, 

 the offspring, has been one of the most potent fac- 

 tors in the multiplication of varieties, the differ- 

 entiation of species and the evolution of life. The 

 division of the sex element is thought by many 

 to be the result of a demand for greater variation. 

 Whether this be true or not, it is certainly one of 

 the greatest causes of variation. Dr. Jordan ob-^ 10^^^ 

 serves, "It is the fact of bi-sexual parentage that Bisexual 

 makes of each individual not simply an 'elongation Parentage. 

 or continuance of the parent/ but a new life which 

 shall be the resultant of the lives and experiences 

 of its ancestors, a mosaic of the characters of its 

 parents and its parents' parentage. By the fact 

 of sex no individual can be the mere slavish copy 

 of any other. Through the operation of sex the 

 law of heredity which is to promote sameness is 

 made subservient to the equal need of the promo- 

 tion of variety."
