Telomeres shortening seems to be clearly implicated in regulation of cell
ageing even though a stronger force should be the II principle of
thermodinamic and its tendency to enthropy. Uncorrected DNA replication
errors accumulate even affecting the same repairing system encoding
genes provoking a cascade effect. But, is the limited number of cells
replication that happens in the life span of an evoluted organism
enough to provoke such number of errors?
Also I am remembering, when I was child, my father used to cut a branch
from a tree, put it in the ground and it grew again to become a new tree.
