being 퀴즈

Slow though the process of selection may be, if feeble man can do much by artificial selection, I can see no limit to the amount of change, to the beauty and complexity of the coadaptations between all organic beings, one with another and with their physical conditions of life, which may have been effected in the long course of time through nature's power of selection, that is by the survival of the fittest.

But I must warn you that chipboard floors are always likely to squeak. The material is still being used in new-builds, but developers now use adhesive to bed and joint it, rather than screws or nails. I suspect the adhesive will eventually embrittle and crack, resulting in the same squeaking problems as before.
