How does, for example, information in DNA accumulates during evolution? Trial and error (natural selection): less complex creature constantly mutates (slightly changes its DNA) and becomes slightly different. Environment then cuts those changes which do not fit it - out of many random mutations only those mutations which accidentally meet changing environment have best chances to survive and multiply. In some cases those mutations result in more primitive DNA (but likely with little chances to survive), in some - in slightly MORE complex DNA.

That is how information accumulates in DNA:
Less complex DNA ----> mutations (changes) adding new random information to DNA ----> variety of DNA ----> survival of some and waste of others ----> more more complex DNA.

No "god(s)" or "intelligent designer(s)", or "subconscious subinformation superfield(s)", etc. are required.
