How to Resurrect an Ancestor 101

First you examine your DNA. there is a list of segments that contain code one segment has your code (number of Man) the next segment up your fathers code the next your grandfathers number the next his fathers. If you know ten generations up is your target ancestor move up ten segments. If you don't know how far up to go you may be able to find it by using a cousin or second cousin that knows he is an offspring of the target. By examining both DNA s you move up the segments until you get to the one that exists on both sets of DNA.
Next find a suitable donor preferably one closely related to you and your target as I believe after this procedure the modified cells may be rejected. Anti rejection drugs may be necessary.

Use a vector a virus is a good vector as it self replicates and will infect or should i say rewrite the donors code with the targets code. This must be done to most of if not all the donors brain cells. The Donor will die his spirit will be disembodied and your ancestor who was watching through your eyes carefully and understands what you are doing will attach him self to the new donors brain. Because neurons are never in the same place from brain to brain there is a learning curve as the spirit will have to relearn all the neuro pathways could take up to six months to a year.
