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?

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

Could those zig-zag lines result from RAT's brushing different layers
of organic tissues instead of inorganic rock?

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.)
