Quoted by K. Pearson, 'Lecture on Albinism in Dogs' (1913).
Description:

'I find nothing to confirm the view that hybridisation is a mere shuffling of definite unit characters. Yet that Mendelian view has been preached by anthropologists, and is being now taught by sociologists wholly regardless of the slender evidence on which it is based. What happens asks Dr Fischer of Freiburg after race crossings?

 

“Does a new race arise? Or a mixed race with blended or new characters? Does one race more or less dominate the other?”

Dr Fischer asserts that the last question has been answered by Bean, Salaman & Davenport for the dominance in hair, eye & facial characters in man.

“Again,” he writes “the answer to the first question has been given by the thousands of hybridisation experiments of botanists & zoologists – no new race is to be expected. Characters always separate out again according to the Mendelian rules, the unit characters are always found in thousandfold combinations, alongside each other. - [..]. characters are persistent, an immense number of combinations arise, but no new race... Von Luschau was the first to emphasise the process, he pointed out how the old types always reappear, types which existed in a country thousands of years ago. Race mixture [19-20] leads, he said, to ‘sorting out’ – (“Rassenmischung zu einer Entwischung”). Today, when we know Mendelian segregation this is intelligible without any further explanation.”

So far Dr Fischer.

According to this view man for thousands of years has consisted of the same component unit characters, endlessly shuffled kaleidoscope fashion. Every character in man as we know him now either existed in Palaeanthropus [sic], or in one of his contemporaries.To take this view is to destroy the whole philosophical basis of Darwinism.'
