Why we are not like ET
<Why we are not like ET Provides insight into the potential evolution of genetic codes on other planets. I think it will be easy to tell life with a separate genesis from Earth's using DNA comparisons. Anything besides a 4 base pair sequence would be a no brainer, but even other fours would probabaly have radical diverences in noncritical areas of their DNA just do to chance.
Computer simulations provide valuable insight in science once again.
