THE ‘LIMITS OF NATURAL SELECTION AS 
APPLIED TO MAN. 
Turoucuout this volume I have endeavoured to show, 
that the known laws of variation, multiplication, and 
heredity, resulting in a ‘struggle for-existence” and 
the ‘survival of the fittest,’’ have probably sufficed to 
produce all the varieties of structure, all the wonderful 
adaptations, all the beauty of form and of colour, that 
we see in the animal and vegetable kingdoms. To the 
best of my ability’ I have answered the most obvious 
and the most often repeated objections to this theory, 
and have, I hope, added to its general strength, by: 
showing how colour—one of the strongholds of the 
advocates of special creation—may be, in almost all its 
modifications, accounted for by the combined influence 
of sexual selection and the need of protection. I have 
also endeavoured to show, how the same power which 
has modified animals has acted on man; and have, I 
believe, proved that, as soon as the human intellect 
became developed above a certain low stage, man’s 
body would cease to be materially affected by natural 
selection, because the development of his mental facul- 
ties would render important modifications of its form 
and structure unnecessary. It will, therefore, probably
