Life existed on Mars, shocking discovery suggests By Margi Murphy, The Sun Nasa's Curiosity rover has detected boron, a key ingredient for life, on the dusty surface of the Red Planet. The discovery is a huge boost in the hunt for extraterrestrials and could back up a theory suggesting life on Mars may have been forced underground when disaster turned the planet into a "frigid desert". Patrick Gasda, a postdoctoral researcher at Los Alamos National Laboratory said : "Because borates may play an important role in making RNA - one of the building blocks of life - finding boron on Mars further opens the possibility that life could have once arisen on the planet. "Borates are one possible bridge from simple organic molecules to RNA. Without RNA, you have no life. "The presence of boron tells us that, if organics were present on Mars, these chemical reactions could have occurred. " After analyzing the text and according to the topic “Origin of the universe and life”, you could say that a. It could not be possible, since life cannot be produce from inorganic compounds as those found on Mars. To start life it needs to have something alive to produce new life. All living things on Earth descend from simple organisms like bacteria. B. It could not be possible, since there is any prove that organics compounds come from inorganic compounds, and God is the only way to explain the origin of life. It does not exist any scientific explanation for the origin of life. C. It could be possible, since as the text says, boron could lead to the making of RNA, and RNA to DNA, and DNA to eukaryotic organisms, and eukaryotic organisms to prokaryotic organisms, according to the endosymbiotic theory. Besides, the Big Bang theory explains the origin of life on Earth, so it could be possible to have a similar explanation of what happened in Mars million years ago. D. It could be possible, since Miller and Urey in the 1950’s demonstrate the Oparin and Haldane’s hypothesis about the origin of organic compounds from inorganic compounds. Thus, organic compounds can lead to the formation of more complex molecules, such as RNA and DNA, and those, to simple organisms, which could evolve into more complex life forms.
