Although this is correct, it is a fallacy to assume that "more DNA"
means "More complex DNA". Much of salamander DNA is in the form of
simple repeats. In this sense, the sentence "To be or not to be"
is more complex than "asasasas dfdfdfdf ghghghghgh hjhjhjhjhj
klklklk" for example. From all the crap in a salamander genome,
you could compress the information required to "make" a salamander
into a much smaller space than that to "make" a human.

I don't see this as a paradox at all - it's just an interesting
phenomenon. Any other thoughts?
