embryonic growth Quotes

Little by little, wean yourself. This is the gist of what I have to say. From an embryo whose nourishment comes in the blood, move to an infant drinking milk, to a child on solid food, to a searcher after wisdom, to a hunter of invisible game.

This work should commence with the conception of man, and should describe the nature of the womb, and how the child inhabits it, and in what stage it dwells there, and the manner of its quickening and feeding, and its growth, and what interval there is between one stage of growth and another, and what thing drives it forth from the body of the mother, and for what reason it sometimes emerges from the belly of its mother before the due time.

Upon the union of the male germ cell with the female egg cell, a new cell is created which almost immediately splits into two parts. One of these grows rapidly, creating the human body of the individual with all its organs, and dies only with the individual.

It turns out that the very genes that turn on in cancer cells perform vital functions in normal cells. In other words, the very genes that allow our embryos to grow or our brains to grow, our bodies to grow, if you mutate them, if you distort them, then you unleash cancer.
