Weekly Seminar on Search for biological activities on Mars and its significance for the origin of life

Dr. Hojatollah Vali from "Anatomy and Cell Biology and Facility for Electron Microscopy Research, McGill University, Canada"


Abstract: Scientists have long speculated about the possibility of life on Mars owing to the planet's proximity and similarity to Earth. It remains an open question whether life currently exists on Mars, or has existed there in the past.Evidence of past liquid water on the surface of Mars suggests that this world once had habitable conditions and leads to the question of life. If there was life on Mars, it would be interesting to determine if it represented a separate origin from life on Earth. To determine the biochemistry and genetics of life on Mars requires that we have access to an organism or the biological remains of one?possibly preserved in ancient permafrost. A way to determine if organic material found on Mars represents the remains of an alien biological system could be based on the observation that biological systems select certain organic molecules over others that are chemically similar (e.g., chirality in amino acids).
