So, in your opinion, no species is related to any other species, and any similarities are purely coincidental?
Just the opposite! I see 25% hard genetic similarities among every living thing, like soil. Actually, I suspect on the animal side of the lawn the similarities will be greater, more like 50% but that's just a guess. It would look like a rise in the soil.
The "grass blade" for a daffodil is on the same lawn as the chimpanzee and the human. The chimpanzee is a tad longer than the human. And there might be a blade with a fork or two where creatures have differentiated to adapt to their environment (like the finches.)
If all the sequences are maintained in drawing it, then to me, the end result will look like a "lawn."
When did we crack the soil genome?
Would you expect a tree built using some set of genes to be correlated to a tree built using some other set? Is suspect you would say no. That seems a fairly easy and definite test.
