Yep some of the more primitive forms of life are still around ie bacteria, viruses moulds, fungi, plants, cuttle fish, squids, fish...
And you can work out how they evolved from look at their genome at the moment. You can see how they branched out for the development of certain characteristics, like different eyes, legs, fins etc
It's just a decently researched Physics paper you can download the original here:

My problem is DNA's nothing like a transistor and who's to say the first part isn't even faster for DNA it then dies down once its established?
But I'm no expert, but it's another thing pointing towards panspermia, that DNA could have evolved on another world.
