4.9/5 (32328 ratings)

Description:Excerpt from The Principles of Heredity: With Some Applications There is a good deal that is new - a little of which I hope will be found true - in this volume. It follows somewhat on the lines of my former work, The Present Evolution of Man, from which I have borrowed occasionally, especially in Chapter XI., and in the section devoted to Mind. The evidence bearing on Heredity afforded by disease has hitherto been scarcely touched. It is utilized largely in the present work. I cannot help thinking that most students of Heredity are not aware of the value of this evidence from disease. I believe that if it had been considered in conjunction with the facts of specific adaptation to the environment a good deal of controversy concerning the transmission of acquirements and the origin of variations would not have occurred, or at any rate would not have lasted as long as it has done. So far as I am able to judge, it establishes conclusively the facts(1) that parental acquirements are never transmitted to offspring, and(2) that variations are rarely caused by the direct action of the environment on the germ-cells so rarely that racial change is never due, directly or indirectly, to this cause. The great mass of variations have another origin which I have endeavoured to elucidate. The function of bi-parental reproduction appears to me manifest. It is very important, but it has nothing to do with the causation of progressive variations. In the fifth chapter I have sought to re-establish on a firm basis the doctrine that the development of the individual is a blurred recapitulation of the life-history of the race. The doctrine of recapitulation has been controverted of late; but in the whole range of biology there is nothing that is more certainly true.
