Mitosis
From zygote, pluricellular organisms are formed through serial mitosis. Had this formation be possible if every cell made by the mitosis had similar life in relation to antecedent cells? How the evolution did solve the problem?
Expert
Formation of complex and distinct pluricellular organisms might not be possible in case mitosis in the embryos had produced the daughter cells having an identical life history as the mother cell, as there would not be any differentiation and structural or functional specialization among the cells. Evolution had solved this problem producing the cellular differentiation process through that, motivated by the stimulus not so far well-known by the science, different and specialized cell lineages gave birth to the different tissues, organs and systems that, as a total, form pluricellular organisms. Cellular differentiation possibly is very intricate process which activates and inactivates some genes in the cell in response to the some stimulus.
