An analogy for evolution

[RichardG (Richard Gillett)]

I would have joined in sooner but i have had a forced silence.

@St.Roymond

And lest someone object that a sandcastle is all the same material

it is not the organs that matter but the cells themselves
composition of sand
And the specialisation of cells
And there are about 200 different cell tpyes in a human
How many cell types in a human

So the analogy fails.

PS Is that enough references?
