Amoeba sp. is unicellular, so can't form a tissue. It need not go through any apoptosis. It just continuously get doubled.
Could we compare them with cancer-cells?
could we tell that cancer-cells are a sort of mutated cell, that is behaving like Amoeba, or behaving in a primitive manner, and lost its later-upgrades?
It seemed to me when I came to know that, mutation in many possible, separate genes, can cause mutation (probably that's why all environmental articles about different mutagens lead to the same disease... cancer). So I was wondering about there could be a common-cause behind all these cancers ... which maybe a loss in all latter-upgrades.
