Answer:
blood cells,stem cells,muscle cells, skin cells.
This is because many organisms have a common descent they may fit into this similar nested pattern, sharing anatomical and molecular characteristics. To this we call homology.
There is, on the other hand, another process called convergent evolution. This process is due to natural selection pressure that affects organisms in different ways according to its needs and environment. For example, when we consider a butterfly, a bat, or a sparrow, we may say that they all have wings, but those wings are not anatomically comparable because they have completely different recent origins.
The human body has over 700 enzymes - each, specific to one particular chemical reaction (within the body.) So, I think that the body will have different enzymes to break down proteins within the body and another, different, protein to build proteins in the blood. Hope this helps.
According to the principle of common descent, all species--living and extinct--are descended from ancient common ancestors. This is <span>Darwin's mechanism for evolution which suggest about living and extinct species. </span>
