The point is to recover the stage for easy future use. How easy will it be to reuse a stage which has been floating in the sea for several hours (minimum).

Also, a longer term plan is to be able to touch down on land, the sea provides a good environment to practice soft landings because when you fail you are a really long way from any people/infrastructure and because with the motion of the landing ship, once you can reliably do sea landings, surface landings should be relatively easy

Also the reason for an ocean based landing is so the booster does not have to do a U turn to come back to the take off location. This means that Space-X can launch a larger payload because they don't need as much fuel for the return. Or do it cheaper.

Submission + - Ford touts self-driving car, launches global mobility experiments

An anonymous reader writes: Ford showcased the semi-autonomous vehicles it has on the road at CES and gave attendees a glimpse into fully autonomous vehicles now in development. The carmaker also announced a series of experiments with drivers around the globe to test its vehicle-to-vehicle connectivity, autonomous cars and the use of big data collected from vehicles. The company said a fully autonomous Ford Fusion Hybrid research vehicle is undergoing road testing now. The vehicle relies on the same semi-autonomous technology used in Ford vehicles today, while adding four LiDAR (light, radar) sensors to generate a real-time 3D map of the surrounding environment.

It is possible, and it has been done. But it takes a specialized organism (bacteria, maybe frogs, some insects) or some way to prevent ice crystal formation... And a mammoth dis not have this advantage. Your references require some quite advanced technology that was not around (that I know of) 43000 years ago. A nicely frozen steak is not viable tissue.

The process is discriminatory in the sense that whatever there is a greater amount of to start with will be replicated/amplified at a faster (also) exponential rate.

Also the samples are taken from the inside of bone/fossilized tissue that has undergone quite extensive cleaning prior to grinding/crushing and processing. It is possible though for contamination to occur at almost any point in the process.
