- colonel_panic 15y agoBit rot is a feature. It allows genes that don't impact survival to attain greater diversity within the population so that, if the environment changes and the gene becomes relevant, some part of the population may be better able to adapt.

- Gatsky 15y agoThis is just hubris. A worm has the same number of protein coding genes as us. Obviously the 'non-functinal' DNA is doing something important, we just haven't worked it out yet. I would be very hesitant to criticize an evolutionary construct that has developed on a billion year timescale.
