When talking about evolutional adaptations, the result can generally be almost whatever you can imagine that being said there are some logical conclusions nature comes down to.
1.A Larger number of muscle fibers.
2.A redesigned rib cage. Rather Series of bars, it's a crisscrossing pattern. With sinewy webbing in between them,
- ok.... just realize the advantage of the human ribcage is its lightness and ability to be both flexible and resistant to compressive forces. Making your structure to rigid can make your final form too inflexible.
3.Muscle fibers are weaved together for better strength.
- Muscle fibers kind of already are weaved together, depending on your "weave" the end result could be counter productive and less efficient
4.Iron in their bones for reinforcement.
- utterly irrelevant. Iron is heavy, solid iron is organically expensive to produce and brittle. Bone is a superior construct because of lightness, flexibility, and organic composition. It can be easily repaired. The thing to remember here is, sometimes how something is made is more important than what it is made of.
5.Denser but heavier brain which allows for more functioning parts.
- Sure why not, though you just as well say their neuron equivalent is superior to our own allowing smaller lighter brains with the same amount of computing power.
6.Stronger neck muscles
7.Scale hide on their back, legs, and arms.
8.A greater amount of stem cells in the blood.
- ok... stem cells are more a mammalian trait (probably reptiles too ) my point is; You don't need stem cells for improved healing you could just as well say all body cells are able to replace damaged cells.
9.A healing factor that uses Stem cells to rebuild sections of the body.
- Stem cells are a healing factor, theoretically they could replace dismembered limbs. The reason they don't is because primarily there aren't enough of them in the human circulatory system. There are other potential factors like telomeric decay.
On the healing aspect another critical factor is metabolism. The bodys ability to process energy which means: capacity of food consumptions, speed to process food into an energy store, distribution of your energy store (nutrients), efficiency of cells ability to use the energy store to achieve their biologic functions.
