Double Helix Culture

A recent study of finches has scientists believing in the possibility that culture could be encoded in DNA. The study involved isolating a finch from learning its birdsong from other finches. It passed down its cacophonous birdsong to the next generation, and so on. But each generation improved the birdsong and after four generations, the original finch birdsong, which was never learned by the first, re-appeared. The implications of the results of this study are startling. If birdsong is encoded in DNA, can other traits in other species be encoded? And if language or culture is encoded in human DNA, how would this effect the notion of free will?

Similar problems, similar tools, similar solutions.
I don't understand how the conclusion follows.
How do we know that they are not simply rediscovering aesthetics?
If two cultures independently invent something, we don't go, "Oh, it's genetic." Rather, we say, "Humans have common needs, and there are good discoverable solutions to those needs."
See also convergent evolution. It's not about similarity in genes; Rather, it's about similarity in problem space and tools available.
I just read a new book on
I just read a new book on bird songs -- the ornithology professor from Massachusetts -- Donald Kroodsma, author of the Singing Life of Birds, provided 2 c.d.s of bird songs with the book. He mentions the interesting case of the song bird without a song. The difference between a "song" and a "call" is that the "song" is used by the male to attract the female and the song is also used for territoriality. But there is a strange case -- cedar waxwings -- of birds that are technically song birds which means they LEARN THE SONGS -- but the cedar waxwing evolved to have no songs -- just a call of chirps and buzzing.
My hypothesis is that there is no song needed because the females are more dominant in the Cedar Waxwings and therefore this changes the father to son song learning. Human language, as per Professor Chris Knight's book Blood Relations and his forthcoming "Human Conspiracy" and his recent "Cradle of Language," coevolved with the female menstrual cycle synchronized with the moon as a "sex strike." Human language enabled long distance hunting -- food for sex -- but human language also enabled Darwinian Deception.
Songs are like mimicry -- used to signal the species. When male birds confront other males they typically go through their whole repetoire of songs in a quick cycle -- to out sing the other male. How many songs do you know? But there is one song bird species where the male, instead of showing off the number of different songs, goes into a song chant with the other male. The same song is repeated over and over with increasing intensity to drive the other male off. The other male responds in kind. This is similar to chickadees use of their one "minor third" call for a territorality prediation warning -- the faster the same "song" the closer the predation threat. As a song increases in tempo the rhythm becomes more chaotic -- it bifurcates and appears to be random or noise. The frequency then increases as well and the intensity then turns back into a "call" -- a buzzing or chirping.
Birds are known to produce ultrasonics and this was left uncovered the bird song book. The "Sonic Bloom" invention by Dan Carlson is based on his University of Minnesota research that bird song ultrasonics perfom a critical role in plant growth -- the stomata of the plants expand in the morning bird song ultrasonics so that plants absorb nutrients from the morning dew. There's a phenomenon called the "Haunting Melody" in Freudian psychology but more recently called the "Ear Worm" -- it's when you can't get a song out of your head. Often this is because the words of the song hold psychological value on a subconscious level -- like a dream -- if you can recall the words then you can probably analyze how the words are solving a subconscious problem. Similarly a song will pop into a person's head and then when the words are remembered it's realized they are pertinent.
Music Darwinian Evolution is the focus of Daniel Levitin's research and I've corresponded with him quite a bit. Music and rhythm activates the cerebellum but does so by deactivating left-brain dominance. Words and language are left-brain dominant. It's been recently discovered that tone-deaf humans actually have neuron damage. Oliver Sacks wrote a book just on this subject -- Musciphilia. Because of brain plasicity music training can actually regrow synapses.
Epigenetics has proven that culture can not only change genetic expression but that the enzyme conditions are passed on in the sex cells with the DNA. When music activates the cerebellum -- the reptilian brain -- then there is actually a transformation of the enzymes and the hormones in the blood changing to neurotransmitters in the cerebral-spinal fluid. The epigenetics is controlled by the electrochemical emotional changes through the parasympathetic nervous system -- and it's like stem cell activation.
As for quantum entanglement -- morphogenetic resonance happens because the energy resonates through time, not limited by space. Classical science defines sound through space but traditional music relied on frequency -- how sound turns into light, used for healing. Sonoluminescence or sonofusion for alchemy. Time, as Rupert Sheldrake argues, is an instanteous resonance and quantum physics has documented this with the evanascent pilot wave -- the future affects the past! DNA transduces the biophoton light based on phase shifts -- the imaginary dimension which uses the pilot wave through superliminal communication.
This would be the species memory -- the cultural memory of that particular bird -- what's call the prenatal vitality in Taoism, passed on not through the parents but through the previous lives of the holographic information stored in the quantum energy of the cells. When the bird song turns back into a bird call then the ultrasound resonance ionizes the electrochemical energy turning it into electromagnetic energy and then into biophotons -- or superliminal pilot waves for spacetime travel. The connection of communication is a phase entanglement so that similarity for adaptation is the guiding information. So did the bird learn the song or is sound the ultimate Darwinian Deception -- and only pure consciousness (infinite time) is real.

Seems an ideal experimental case for Rupert Sheldrake's hypothesis of morphogenetic fields alright.
