I'm building some alien cultures for my fictional universe. One race has advanced technology and culture enough to have accepted, regularly occurring, DNA modification available (EDIT: regularly occurring among the race as a whole. Individual adaptations take many years).
This race values intellect and advancement, seeing all other species as equal and as having something to teach them about the universe and their own unique perspectives. The main goal being to try and contact a "God" they've experienced glimpses of.
As thus, their modifications are peaceful in nature and are mostly used to make life easier for their society as a whole
- ie. creating a more efficient way for their bodies to utilise calories/nutrients/macros
And to gain a deeper knowledge of other races
- ie. living in the copies of physical forms of other species in their own daily life or in disguise on the other species' own planets
Another idea I had for energy intake/usage efficiency is using DNA modification to adapt skin cells to incorporate chlorophyll which allows the body to use sunlight for energy. I've also considered incorporating the ability to absorb kinetic energy from the surrounding environment (warmth/wind/impact/motion etc) to be utilised in the body also.
With these modifications in mind, what foods would these aliens' diets consist of to make up for the nutrients not gained from the sun/surrounding energies absorbed etc.?
Thanks in advance for your thoughts and answers! I look forward to the discussion.
