Isn’t aging engineered into an organism? This seems self-evident because rats and humans are made of essentially the same biological stuff, but rats live for 2-3 years (and then die of old age) and humans live for 25x that. Maybe this theory explains how organisms “create” aging. It also implies that aging can be slowed or reversed, and the mechanism for doing that is already present in any organism.

It’s better explained by the reverse. Human evolution needed to fight aging harder in order to be successful.

Also, we aren’t made from the same biological stuff, or we would be rats. It’s easy to think of biology in overly simplified terms but cells aren’t legos.
