why regeneration of body organs in humans are not developped?

Apparently, the process of evolution of the Human species has found no particular reproductive or survival advantage for it.

Who would develop this? You'll probably need to ask God.

Remember, skin can regenerate,and it is an organ. Liver cells can regenerate, with the right stimulus.

The regeneration of body organs in humans is not as developed as in some other organisms such as salamanders or starfish. This is mainly because humans have a more complex biology and specialized organ systems.

One reason for limited organ regeneration in humans is the presence of scar tissue formation. When organs are injured, the body responds by forming scar tissue, which helps to heal the wound but does not restore the original organ structure or function. Scar tissue lacks the specialized cells and intricate architecture that make up organs, making it difficult for organs to regenerate fully.

Another reason is the lack of specialized cells called progenitor cells in most adult human organs. Progenitor cells are necessary for organ regeneration as they have the ability to differentiate into various cell types and replenish damaged tissue. While some organs, such as the liver and skin, do possess limited regenerative capacity due to the presence of progenitor cells, many other organs, such as the heart or brain, have limited or no ability to regenerate because of the scarcity of these specialized cells.

Additionally, the complex structure and function of organs in humans make complete regeneration challenging. Organs consist of intricate networks of cells, blood vessels, nerves, and connective tissues, which must be restored in a coordinated manner for proper organ function. Achieving this level of regeneration requires precise cellular and molecular interactions, which are still not completely understood by scientists.

It is important to note that although humans may not have extensive regenerative abilities, advancements are being made in the field of regenerative medicine. Researchers are studying different approaches, such as stem cell therapy and tissue engineering, to promote organ regeneration in humans. These efforts show promise for the future of regenerative medicine and could potentially enhance the body's ability to regenerate damaged organs.
