I found very strange zig-zag lines in above Martian image link.
Do Earth rocks have similar zig-zag lines after a Rock Abrasion Tool
(RAT) has brushed them?
Could those zig-zag lines result from RAT's brushing different layers
of organic tissues instead of inorganic rock?

I think those lines may be some kind of optical artifact, pergaps
compensation for a shadow. See he

Do you think that those two are the only alternatives? (Be careful about
the word "organic". It means different things in grocery stores and
chemistry labs.)
