Size and deviation - of flies and sheep

On size and deviation
POV you're a fly
You have fewer cells
If one cell fails, or perturbs other working cells
The other cells are more likely to fail
Than POV you're a sheep
That one cell that doesn't work
There so many more that do work
That that one cells nonfunction
Is inconsequential to the rest of the sheep
This would favour evolution of large size
Over the evolution of small size
It takes a lot more network robustness
To create a small precise system
As one cell would be sufficient to topple the whole system
Meanwhile in the big system
Fuzzier logic can apply
More cells can afford to go wrong
While the system maintains a semblance of function
Just some thoughts while staring at the wonderful
Black or white sheep
Of the Scottish Highlands
And comparing them
Against the black or yellow flies
Who are very much smaller
Than the sheep
