Not all genes have to have a function, or even a beneficial one. DNA could be riddled with legacy (inactive) code. As long as there's not enough evolutionary pressure -its negative value doesn't pass a threshold- the code would be retained.
- Dowwie 9y agoI wonder what other dormant code exists that if toggled would trigger dramatic changes
- stochastic_monk 9y agoConsider an extremely high-dimensional feature space [not just genes, but transcripts/isoforms (differently diced-up versions of RNAs with different functions), hosts of active-but-not-transcribed-into-proteins RNAs, and dynamic regulation through interactions] which updates a reinforcement learning algorithm one epoch per generation (~20-30 years), and you'll see why it's far from optimized.
