Genome evolution

[JCVentner]

If we can see traits appear in the genome can we work backwards to trace this down to the original DNA combination? Or possibly estimate "times" of change? I'm guessing that adaptations come about to solve an evolutionary problem therefore, can we interpret that information to tell us about the environment at specified time? If we began in the ocean we most likely did not have hair so when and why did it come about? A cooling of the planet or just a migration to a colder climate possibly? And lastly, I'm assuming that we didn't always have 3 billion letters ACTG. Are they particle and anti particle similar to quarks? So can we trace that back to the "elementary particles" of DNA? And if so, at what rate do the letters (variances?) increase? Aloha.

Based on the 'evolution' myth we should be ADDING ~1 bp a year to our genome. 3.5 billion years since alleged LUCA. 3.2 billion (our genome) - 150,000 (smallest prokaryotic genome) =~3 billion /3.5 billion years= ~1 base a year 'evolved'. HAHAHAHAHAHAHHAHAHAHAHAHAHAHAHAHAHA. People could be looking for this but they are not. looool

Yeah, like if the genome as growing by single nucleotides :-/
