Solution
The following pieces of evidence would strongly suggest the former existence of animal-like creatures on Mars:
-
Fossilized creatures with evidence of head and tail ends as well as evidence of bilateral symmetry. This suggests a level of complexity and organization that is characteristic of many animal species on Earth.
-
Fossilized creatures with evidence of other creatures inside them that have been partially digested in a digestive tract. This suggests a predator-prey relationship, which is a key characteristic of animal ecosystems.
-
Fossilized genetic material that, when engineered into protist cell genomes, promotes the production of unique extracellular junctions between protists. This suggests the existence of complex multicellular organisms, which could include animal-like creatures.
The evidence of fossilized creatures with cell walls surrounding inflexible cells is less indicative of animal-like creatures, as animal cells typically do not have cell walls. This evidence might suggest the existence of plant-like or fungal-like organisms instead.

Fossil body parts of an animal and its location of excavation confirm that these animal species underwent minimal adaptations from one period to the next.
Fossils provide clues about the history of life on Earth. Paleontologists discovered a fossilized creature with a segmented body and a hard exoskeleton. They also found faint traces of what might have been small limbs.
How do fossils demonstrate evidence of evolution?
Scientists have discovered several fossils ranging from 2 to 9 million years old that they believe to be ancestors of a present-day crustacean species. Other than differences in overall size, the fossils appear to be almost structurally identical to the living species. Which of the statements is the MOST reasonable explanation for this observation?Select one:a.The fossils found are not as old as scientists believe them to be.b.The fossils and present‑day crustacean species are an example of convergent evolution.c.Stasis is occurring in this crustacean species.d.Structural features cannot be accurately identified in fossils.
