A recent study suggests that microscopic life on Mars billions of years ago, when it had an atmosphere similar to ours, died out due to climate change. It is believed that by modifying the atmosphere of its native planet, microscopic Martian life may have unintentionally exterminated itself. According to the study, the differences in the two worlds' atmospheric compositions and distances from the sun account for why life first flourished on Earth but died out on Mars.
