If then our diagram be assumed to represent a considerable amount of modification, species (A) and all the earlier varieties will have become extinct, having been replaced by eight new species (a14 to m14); and (I) will have been replaced by six (n14 to z14) new species.
The new species in our diagram descended from the original eleven species, will now be fifteen in number.
In our diagram, this is indicated by the broken lines, beneath the capital letters, converging in sub-branches downwards towards a single point; this point representing a single species, the supposed single parent of our several new sub-genera and genera.
We shall, when we come to our chapter on Geology, have to refer again to this subject, and I think we shall then see that the diagram throws light on the affinities of extinct beings, which, though generally belonging to the same orders, or families, or genera, with those now living, yet are often, in some degree, intermediate in character between existing groups; and we can understand this fact, for the extinct species lived at very ancient epochs when the branching lines of descent had diverged less.
We shall also have two very distinct genera descended from (I) and as these latter two genera, both from continued divergence of character and from inheritance from a different parent, will differ widely from the three genera descended from (A), the two little groups of genera will form two distinct families, or even orders, according to the amount of divergent modification supposed to be represented in the diagram.
On the view that each species has been independently created, I can see no explanation of this great fact in the classification of all organic beings; but, to the best of my judgment, it is explained through inheritance and the complex action of natural selection, entailing extinction and divergence of character, as we have seen illustrated in the diagram.
For example, Whitten and Bentley (2007), used a data flow diagram to illustrate all the phases of the SDLC.
Kanok (1992) divided all diagram symbols according to the method of construction and according to the number of phenomena.
At times, they can diagram a sentence w/o understanding much about the whole sentence structure or even the individual words.
Air-conditioning calculations are based on a diagram where the complete process of change in air treating or air handling may be presented, with all the conditions through which the air passes, from its outside state to its relocation into the air-conditioned space.
What makes the diagram so intriguing is that it often conveys something which cannot easily be put into words--that is the point; it is the coded language of creative design intelligence which does not automatically operate successfully in the world of bureaucratic tick boxes or cultures in which verbal or literary skills are too dominant.
A common rule is that time advances from the bottom to the top of the diagram.
