If our basic consciousness is based on energy, then can a being manipulate their DNA? Can a person or being change their physical body into another form? Could there be beings more advanced than us? Are we just unaware? Lets look at possibilities.
For centuries farmers and breeders knew techniques for selective breeding, often referred to as Mendelian genetics. In the late 1960’s and 70’s enough was known about DNA to start manipulating the genome. By 1998 a rough draft of the human genome was mapped out. For more about manipulation of the genome see Harvard Education.
Squid and octopus are able to change their colors so that they appear completely different. Studies confirm that these traits can be genetically engineered so it’s possible for someone to do this. Although changing color is only one aspect of changing one’s appearance. Starfish can regrow portions of their limbs if they’re cut off. Bioluminescence can also be factored in.
Although small changes are possible but a full shift to change form? Stem cell research confirms they can regrow parts. Having a port or reservoir inserted and cell phone or other trigger to release new cells, but this would take time and energy to change anything. If technology could overcome these obstacles anything could be possible.
