>>11021787True other animal have internal setups, but have you seen how different their DNA and operations really are? I mean it is all interrelated, you can't simply change one thing that easily.
If we are going to dumb it down that much then we can just look at how human body is basically a radiator to dump heat from the brain. Cooling the system for internal testicles would have notable impact on mental ability given current setup if we just lowered body temps. You could address that any number of ways, like a longer neck or less temperature sensitive sperm, but that just makes other problems.
Not trivial at all. You may notice different part of the body repair differently, and we are talking about the back, or I believe more specifically the spine. Regeneration is largely dictated to the system being restored. The reason why advanced material systems are trying to copy the human back is because it works so well overall. Animals that have impressive spinal recovery tend to be far less rigid and often more aquatic in nature. That may sound cool, faster spine healing and less rigidity don't sound like down sides.Till you think about how other organs need the spine to be rigid. For things like being tall and bipedal, to an anchor point for our lungs.
>>11021729No, we are trying to better regulate heat.
Putting a fusion reaction next to your ball just makes more thermal management issues, not less.
