How to balance evolution

Hi there!

I have an idea to balance the evolution and keep selfish genes from appearing.
In nature important parts of the dna are less prone to mutation because they are more protected by the cell mechanisms.
Similarly you could randomly give a cell mode a protection (engrainment in the genome), making it less prone to mutation.
I would think of a sort of mutation buffer that can build up as the organsism acquires it.

Because the less mutation prone organisms will survive (because of less random junk mutations they have evolutionary benefits) the mutations will happen less in the essential parts of the genome.

Specifically the buffer could go from 0 to 100%
When a mutation comes it can decrease or increase this counter or mutate the cell mode. When the counter is for example 50% the random mutation will have a 50% chance of changing things about the cell mode. But the mutation doesn't have a decreased chance to fall on the buffer making it increase or decrease.

You can set the amount of mutation right?
Also, selfish gene is a part of evolution. I dont think we need to prevent selfish gene.
Second also, how does codes even determine if someone is selfish? That would take a lot of time and thinking.

I'm not sure that "nature mechanisms" work exactly as you mentioned.
Yes, there are mechanisms that protect DNA from mutation in nature, such as junk DNA and antimutagens.

Junk DNA is useless parts of DNA. Human DNA has 98% of junk DNA, so mutations have only 2% chance to change the phenotype. This mechanism is present in cell lab. Most of the organisms do not use all 40 modes, so the unused modes can be considered "junk".

Antimutagens are quite similar to the mechanism you mentioned. They stop DNA from mutating or repair it after it mutates. Antimutagens in nature are vitamins and are not controlled by evolution.

Now let's talk about the mechanism you suggested. For example in the beginning all the modes have 0% protection from mutations. And then some useleess gene mutates and becomes protected. So this useless gene will stay in the genome for even longer as it is more protected.

As i see it random phagocytes appearing from a genome is a sort of "cancer" with these adaptations every organism will evolve to a sensitivity for mutation that still allows evolution but not so much that cancerous tissues can drive it to extinction (phagocytes that just copy their selves appearing to much) This is indeed already possible by just lowering the mutation rate to the wanted level where the organism will not die out because of radiation. But if you had a mutation buffer, organisms could also survive higher rates and organisms that require different levels of mutation for an optimal evolution rate could co-exist in the same inviroment.

"Most of the organisms do not use all 40 modes, so the unused modes can be considered "junk"."

The junk dna in cell lab is not really junk, because it causes actual change to the organism unlike our "junk DNA" (that seems to have an actual regulating function too so it's not really useless.) It would be actual junk if the amount of cell modes could increase trough mutation too. Then the amount of genes rises and every mutation would have less of a chance to fall on the important parts.

"And then some useless gene mutates and becomes protected. So this useless gene will stay in the genome for even longer as it is more protected."

As for this: the organisms that protect useless genes will not have a pressure to acquire more mutation protection but they can indeed. But they alo have an equal chance to mutate to have less protection and that is the part i think you missed because this way the netto effect will make it not to go up or down in the average of all the organisms of the "species". Protection of negative genes will rapidly die out due to natural selection but the ones with protection of "positive genes" will have better survival chances in the long run.

"Second also, how does codes even determine if someone is selfish? That would take a lot of time and thinking."

With selfish, i mean for example an occasional phagocyte mutation which eats up all the food around the food finding organism and dies out immediately after, leaving the food finder without food making it die.
but also 'a disease' can happen that makes the swimmer go in circles. you could protect every factor the cell modes have by a different amount of mutation protection.

I imagine this taking up a lot of extra memory tough.
Maybe an on-off mechanism for mutation sensitivity in every part of the gene would also be enough.

I mean, they are code not human. Maybe its just an egg that need a lot of energy so that it can split quick enough? What if it is intentional parasite?

I don't understand what you mean, simple organisms would also build up protection. If that's what you meant.
