Asteroid impacts and life on Mars.
“By recreating the violent shock of an asteroid impact, scientists found that a famously resilient bacterium can survive the crushing forces that could launch it off Mars. The discovery strengthens the idea that life might hitchhike between planets after major cosmic collisions.

Could life be born on Mars? Or did some other asteroid bring those organisms' ancestors to the Red Planet? Another thing is also interesting. If the meteorite Alan Hills, ALH84001, involves remnants of ancient microbes. Could those microbe remnants come from Mars? There is also a possibility. The temperature of that meteorite. Which fell to Antarctica, acted as a call signal for some bacteria that might not be anywhere else than in the Antarctic ice. This is the reason why researchers should collect sample...
