Investigating it under the new light of natural selection, he came to the conclusion that the existing oaks are all descendants of earlier forms, and that no clear line can be drawn between the diversification whic h has resulted in species and that which is exhibited in races and minor varieties.
In the Australian mammals, we see the process of diversification in an early and incomplete stage of development.
But this is as nothing compared with the arrangements in orchid-flowers, where new and peculiar structures are introduced structures which, once originated and then set into variation, may thereupon be selected, and thereby led on to improvement and diversification.
Of course, I feel the change; it has taken my life out of its accustomed channel, but I am optimist enough to hope that even this change will result in greater good to the greatest number. I think one of our great wants is the diversification of our industries, and I do not believe it would be wise for the parents to relax their endeavors to give their children the best education in their power.
Here the fact of the antiquity of creation, and in particular of the present kinds of the earth's inhabitants, or of a large part of them, comes in to rebut the objection that there has not been time enough for any marked diversification of living things through divergent variation not time enough for varieties to have diverged into what we call species.
If theories of derivation could only stop here, content with explaining the diversification and succession of species between the tertiary period and the present time, through natural agencies or secondary causes still in operation, we fancy they would not be generally or violently objected to by the savans of the present day. But it is hard, if not impossible, to find a stopping-place.

Across southern Africa from Rhodesia to Namibia we are helping with the peaceful transition to majority rule in a context of respect for minority as well as majority rights. We have worked domestically and with our allies to respond to an uncertain energy situation by conservation and diversification of energy supplies based on internationally agreed targets.
In this region, for instance, where there are few bold natural features, the best effect to be obtained was that of a smiling, peaceful landscape with as much diversification in detail as possible.
"Slavery merely serves to appropriate the wages of labor it distributes wealth, but cannot create it." It involves expenditure in acquiring early population, then operates to prevent land improvements and the diversification of industry, restricting, indeed, even the range of agriculture.
