So since the Higgs Boson thing, I haven’t really written much about science. I thought I’d do a quick one on panspermia to amend this little problem.
Of all the theories on how life on Earth originated (or to be more specific, how it accelerate at such a rate), panspermia stands out as the most likely (in my opinion).
We all know life evolved over billions of years (it’s estimated that the earliest forms of life existed on earth around 3 billion years ago, if I remember my astronomy course correctly), but there was a period of time where evolution was sped up beyond predicted levels, allowing multicellular lifeforms to evolve in a much shorter time than they would normally have needed. I feel lazy tonight so I’m going to do most of this off the top of my head. If there’s anything I’m a bit hazy on, I’ll say so. I’m pretty solid on my facts of panspermia itself, I’ve just forgotten the exact timing and order of bacterial evolution on Earth. Feel free to research this yourself.
