>>13221040Transposon activation, telomer degradation and random mutation together, but especially transposon activation cause aging to be an exponential process.
>>13221523If that were the only reason, the age at which people die would grow linearly, whereas it grows exponentially. This is caused by random mutations and changes in chromatinisation allowing previously muted mobile genetic elements to activate, acting as mutagens.
>>13221544No one is meant to do anything, shit just happenes. In this case, the shit that happenes, is retroviral elements being passed on, as they have a shor tearm evolutionary advantage (they kill cells on the bath to becomeing cancerous) which outweigh their long tearm downsides (age related ilnnesses).
>>13221640The protein which replicates DNA is not perfect, nor are the DNA repair proteins. Things at a molecular scale are very stochastic, particles move and vibrate almoust at the speed of sound. Also, there are free radicals and other mutagens, even cosmic bacground radiation causes mutations.
