Life Begins – Science of the Womb

Four statements seem particularly interesting, but the entire video is worth watching:

“Once within the egg wall, the sperm’s nucleus is drawn toward the egg’s. The two cells gradually and gracefully become one. This is the moment of conception – when an individual’s unique set of DNA is created – a human signature that never existed before and will never be repeated.”

“The mother provides the shelter and the basics – food, water and oxygen. But the real star of the show is the fetus herself – building, dividing, growing according to an intricate set of plans created at the moment of conception.”

“The genes she’s [the girl shown in the womb] inherited already predetermine her looks and much of her character. Whether she’s stubborn or intelligent, a thrill-seeker or good at music and even her vulnerabilities to certain diseases like cancer, schizophrenia and diabetes. The exact course of her life will depend on such things as her friends, family and environment. But at the instant of fertilization, much of her future is predetermined.”

“Where it once seemed that the mental development of a baby began at birth, now it appears that birth could be a relatively insignificant event in developmental terms. She may have to support herself after birth, but as for the process of thinking, learning and remembering, she’s already been hard at it for three months [before birth]. And her brain will continue to grow at the same rate for the next year.”
