What you do not understand here, that those are photographed images.
You can do all sorts of measuremens on them.

OK, let's see the "measuremens" that you've done on them.
At a minimum I'd be looking for:
a) a clearly stated, objective protocol for selecting which rocks from among the tens (hundreds) of thousands in the various Spirit and Opportunity photos to study
b) a clear, unambiguous description of the classes of measurements that you will be making on the selected rocks, and how you will make those measurements
c) the results of the measurements
d) clear description of why particular 'biological' objects were chosen for comparison (and not others)
e) a published database of measurements of stingrays, lambs, outposts (etc)
f) detailed comparison of the two sets of measurements
g) the results of running the same exercise on a set of a similar number of Earthly rocks, say a lava field, or a talus slope (which are fully described, so, for example, any PF member could go there are make the same measurements).
Oh, and a statistical analysis of the significance of any noteworthy findings would be nice too.
Seems like a lot of hard work, doesn't it? Well, that's what the nitty-gritty of actually *doing* science is all about :surprise:
