(All are controversial)
| Seasonal shade and/or color change of darker regions on Mars | |
| “Sinton Bands” spectroscopic evidence of organics and carbohydrates only in the darker regions of Mars | |
| Viking Lander Labeled Release Experiment positive results (potentially showing biologic activity) | |
| Meteorite ALH 84001 originating from Mars and found in Antarctica showing several lines of evidence indicating fossilized bacteria. | |
| Measurements of seasonal methane changes in Mars atmosphere showing possible biologic activity | |
| Images from rover Curiosity showing several possible indications of ancient microbial mats on Mars | |
| Significant seasonal changes in Mars oxygen level showing possible biologic activity |
