Is a fetus the equivalent of a skin cell?
Just a little something that wcforcier said in my debate 'what makes a human human?'.
Of course not.
- Quantatively, 1 skin cell is 1 single cell, whereas a fetus is many more cells.
- Qualitatively, both are human, but a fetus has more potential and is unique (the skin cell is from an existing human with his/her DNA, a fetus has its own unique DNA).
If the foetus is around sixteen weeks old, it's more than a skin cell, because it has developed some brain tissue.
However, if you're trying to be technical, a foetus is never a skin cell, in equivalence, because it is multicellular. A zygote is closer to a skin cell.
