The constraints of DNA over RNA. That checksum double helix has slowed evolution up, which is what makes gene therapy interesting as a military application to survive hostile environments. Some bacteria like bacillus can survive radiation levels 100,000 times more than humans. Personally I think if you can get a good idea of what the land based environment was like back then, you'll have a better idea of what changes are needed to extend lifespans in order to watch evolution taking place before your eyes. Currently only viruses and some bacteria like Gram negative pseudomonas can evolve quickly to changes in their hosts environment. What makes their discovery interesting is the use of berthierine, an iron rich, aluminium rich clay. >The analysis found that fossils with exceptional BST-type preservation were particularly enriched in an antibacterial clay called berthierine. Pseudomonas loves iron in all states, and its bacteria that destroy skeletons, once animals and insects have picked at the flesh, so there might be some mileage in using aluminium based deodorants for a starter, in order to reduce bacterial levels as a strategy to extend lifespans, besides dietary supplements and fine control over our environment, like air quality.
