chunks get blasted off essentialy whole and unmodified, as they are contained in bigger chunks that act asl launch shields, though will exerience truely massive acceleration and then renentry on earth and other bodies. The evidence for life on mars is based on carbon nodules in rock, and things like CO² and methane gas,and some other chemistry and mineralology. The main one are the carbon nodules, which are ubiquitous in many sedimentary rocks on earth, though in the samples that I have of earth rocks, there are very often macro fossils that are naked eye identifiable There are countless miles of cliff here where everything has a fossil, but complete specimins, and soft tissue fossils remain rare, here, so the chances of such a thing making it to earth from mars, schould it exist in the first place are almost zero, though the martian ice caps could concievably hold meteors with earth life fossils that are naked eye visible and identifiable.
