Our work shows that even major morphological changes are controlled by relatively simple mechanisms.

That is obviously false. Sticklebacks with major changes in skeletal armor and fin structures are thriving in natural environments. And the major differences between forms can now be traced to particular genes.

In simple terms, the data shows that in mammals each individual gene uses multiple different mechanisms to produce different forms of protein. In a sense, each 'gene' is actually multiple different genes,

We may have to have a geo-political regrouping or major geo-political changes.

major logistical, geographical changes.

If I should sell both my forenoons and afternoons to society, as most appear to do, I am sure that for me there would be nothing left worth living for. I trust that I shall never thus sell my birthright for a mess of pottage. I wish to suggest that a man may be very industrious, and yet not spend his time well. There is no more fatal blunderer than he who consumes the greater part of his life getting his living.
