why do organic bodies degrade over time and not continually regenerate?
In: Biology
They do continually regenerate, but to do so perfectly without error, and while correcting all kinds of problems that slowly get introduced… that’s difficult! You need different processes to heal different kinds of problems. Then you’ve introduce complexity, so that too needs controls and processes so it can keep working (and not break in a dangerous way)
So the longer an organism is meant to last, the better it handles all these things (evolutionary pressure). The simpler the organism, the better it handles this (needs less complicated systems of maintenance)
Eg: Cancer is cells trying to continually regenerate, and eventually breaking and going out of control. We have a special process in our body to capture and kill cells which are going cancerous, and it’s not a perfect process. So our body actually constantly “cures” cancer, until some appears it cannot handle.
– if we change it to be more sensitive and attack the ones it lets thru? You get the body attacking normal body cells “just in case”. Autoimmune
