Say if you’re in space, searching for life, what do you look for? That’s simple. You look for something that resembles life on Earth; whether that be single-celled amoeba or a Star Trek-style humanoid with a lumpy head and webbed feet.
That’s life we know and understand (with some sci-fi comedy thrown in). What if there are some other unimaginable creatures that may not fit into our understanding of How Things Work™? This is a very real problem NASA has been faced with ever since the agency started sending probes to Mars and spacecraft beyond the Solar System itself. Deep space missions (like the Voyager and Pioneer probes) have intelligent life forms in mind (i.e. ones that can read, hear and interpret the Leonardo da Vinci Vitruvian Man; so it would be nice if ET also has an appreciation for fine art), but our intrepid Mars rovers and landers that have been pestering the Red Planet since the 1960s are looking for the basic building blocks of life, plus evidence of past or present life. So far, there’s been a lot of rocks turned over, yet no sign of extraterrestrial life.
Therefore, scientists at a very early stage defined “life” as a self-sustaining chemical system capable of Darwinian evolution so we can focus on finding life we know and understand. To boost this understanding a little further, wouldn’t it be great if we could create our own evolving soup of chemicals?
Now, it seems, this has become a reality. Scientists in a Florida lab have created a beaker filled with synthetic life…
