By this argument, culture can be imprinted into DNA too, no?
This also implies that it would be much tougher to do a Jurassic Park recreation, because the environment is different. You can't just start from scratch with the DNA.
Or am I misinterpreting?
- MacsHeadroom 13y agoYou are absolutely correct.
- MacsHeadroom 13y agoYou are absolutely correct.
- Retric 13y agoIt's a mistake to think there is only one correct path when talking about DNA. Often, there is quite a bit of redundancy involved so Jurasic Park dinosaurs may be slightly different than there historic counterparts but that would not prevent them from being sufficiently viable to pass on there DNA. Because, biology is PASS / FAIL not some pursuit of perfection.
- 3am 13y agoYou are misinterpreting. As others have noted, this is DNA in the nuclei of nerve cells, not gametes. It is not heritable.
- voidlogic 13y agoThis, thank you. People often forget about this when they are thinking about environmental elements modifying DNA.

- pygy_ 13y agoCulture is related to implicit and explicit memories shared by many people. So (supposing that the results of this study can be generalized), yes, culture ends up imprinted in neuronal DNA, one cell at a time. Since the imprinting is distributed and varies among the billions of neurons in your head it will not be passed to descendants (which inherit half a cell's worth of DNA).
