He not only recognises the physical cause of a given effect in his environment, but often adjusts the cause so as to produce the effect at will. Instead of being entirely controlled by nature, he to a considerable extent controls the operations of nature by taking means to counteract them.

In the address which I had the honour of delivering in 1893, as President of the Anthropological Section of the British Association for that year, I advocated the hypothesis that the origin of the higher mental manifestations of man was primarily due to the attainment of the erect attitude, which, by entirely relieving the fore limbs of their primary function as locomotive organs, afforded him the opportunity of entering on a new phase of existence, in which intelligence and mechanical skill became henceforth the governing factors. With the completion of the morphological changes involved in the attainment of this attitude, the evolution of the present human form, with the exception of some remarkable modifications in the skull and facial bones which will shortly be described, was practically completed.

As soon as bipedal locomotion became habitual and firmly secured on an anatomical basis, it does not appear that the osseous characters of the lower limbs would be sensibly affected by any subsequent increase in the quantity or quality
