Conception to birth timeline

The 2015 article “Why Science Can't Say When {?} a Baby's Life Begins”, by Sarah Zhang, discusses the work of Scott Gilbert, a “developmental biologist”, who says that modern scientists have no consensus on this question, and that it only becomes more complicated and confused, with the advance of knowledge.[1]

In timelines, conception to birth timeline (LH:1) refers to the days before and the "conception day" of a human, up to the day of "birth", when the infant emerges out out of the womb, and the proximal days afterwards, e.g. infant, toddler, child, teenager, detachment from home into the "single adult" state, in respect to when a human becomes an individual person, aka personhood. The timeline focuses on questions such as the defined "start" of the following: "life", "soul", and "consciousness", as historical and modern views have argued.

Overview

Most couples, according to recent data, date for two or more years before getting engaged, with many dating anywhere from two to five years. Once the question is popped, the average length of engagement is between 12 and 18 months.[2] The mean of this data, for in-wedlock births, is "3.4 years", which account for 60 percent of births, presently, in the US. For out-of-wedlock births, recent estimates (Child Trends, 2018) show that about 40 percent of births in the US occur outside of marriage, up from 28 percent in 1990. These rates, however, will vary per culture, race, or ethnicity (white: 28%; Hispanic: 52%; black: 69%).[3]

Humans, on average, tend to gestate, in the womb, for exactly nine "lunar months" (29.531) or 266 days. This is the number of days from "day of sex" to "birth". Hence, if a woman knows exactly what day they conceived, the can check their expected due date in a pregnancy calculator.[4] The range of normal pregnancies last between 37 and 42 weeks.

Physicians, however, generally refer to the human gestation period as being 280 days, or 40 weeks, from the first day of the woman's last menstrual period. On average, 14 days after a women's "period" (40wk), she will "ovulate" (38wk), and this will be the best time to conceive. The medical term for the due date is "estimated date of confinement" (EDC), aka estimated due date or simply "due date". However, only about four percent of women actually give birth on their EDC.[5]

Timeline

The following is the timeline of the synthesis and birth of a human, scratch to finish. The following is the basic 18-year human reproduction reaction, showing 3 years before birth (initial state) and 15 years after birth (final state):[6]

where Mx is the male, Fy is the female, G1 is the sperm (germ cell), G2 is the egg (germ cell), MxFy is the couple in the married state, and G1G2 is the newly formed (synthesized) child. It is in this so-called physical chemist "from above" view, aka advanced view, that we want to think about the following timeline.

Date Period Sex Day Ovulate Day Sex Day Zygote Morula Blastocyst Neural Tube Ensoulment Embryo → Fetus Birth
Age -5yr -4yr -3yr -2yr -1yr (52wks) -40wk Conception day? -38wk [+3-4d] [+5-6d] [+25d] [+29d] / [+4wk] [+29d] / [4wk] [+33d] [+5.5wk] [+40d] [+52d] [+59d] [+9wk] [+10wk] [+20wk] [+6m] [+9m] 0 +1 +15 +16
Summary Presently, in the US, 60% of parents, of in-wedlock babies meet at 3.4 years before marriage. Man and two women.png Presently, in the US, 40% of babies are conceived by out-of-wedlock parents; herein, we will guesstimate that first meeting occurs in the 14 week (3.5mo) to 66 week (16.5mo) range prior to conception (-38wk). Female has her menstrual cycle. Note: if the parents have before the day of ovulation, it tends to be a girl (male).[7] The woman ovulates:

Note: if the parents have sex on or after the day of ovulation, it tends to be a boy (male).[7] Sperm swims towards egg:

At day 40, the "male" embryo becomes "ensouled" (Aristotle, 350BC), wherein its "vegetable soul" becomes an "animal soul" (see: anima).

Note: dates shown in square brackets, e.g. [+10wk] is the day the fetus heart if fully formed, refer to dates counting forward from the day when the sperm made contact with the egg. Other dates shown count either forward, e.g. +15 refers to the a child aged fifteen and -4yr refers to four years prior to the child emerging from the womb.

Discussion

The timeline, in idea origin, is an expansion of the Goethe timeline, in respect to being a focused and expanded look at the so-called "birth range" of the origin of "Goethe", with focus on intricate questions such as "ensoulment" (Greene, 2013) or "when Goethe became alive" (Thims, 2014).[17] In short, any particular point picked on this timeline for when "life" started, if argued from a physico-chemical point of view, will result in scientific jabberwocky.

Quotes

The following are related quotes:

“Does god attach the soul when the head of sperm makes contact with the zona pellucida? Or does ensoulment occur when the sperm hits the cell membrane? Is it enough for all of the sperm’s genetic material to enter the egg cell? Or does god wait until the male pronucleus and the female pronucleus have fused? All the way fused, or partway? Whatever it is that makes people worth of moral consideration, these things don’t all appear in one magic moment. Without a ‘magic moment’ to believe in, pro-choicers simply have to draw the line somewhere, while acknowledging that the line they’ve drawn is somewhat arbitrary.”
Joshua Greene (2013), Moral Tribes: Emotion, Reason, and the Gap Between Us and Them (pg. 326) [18]
Beg, said another way, if you prefer not to digress on yourself, in what year did Goethe, in your view, come “alive”? Possible answers, from you, might include: the hour his parents, Johann Caspar Goethe (1710-1782) and Catherina Elizabeth Goethe (1731-1808), had intercourse (sex), calculated to have occurred at noon on 21 Dec 1748, see Goethe timeline sketch: (Ѻ), a process which leads to the five-step mechanism by which the interaction of the sperm and the egg to form zygote generally proceeds (Ѻ), or the hour at which he emerged from the birth canal, which he says occurred at noon on 28 Aug 1749, and took his first breath, or the year he reached the age of one, which occurred on 28 Aug 1750, being that some cultures don’t recognize infants as people until they reach the age of one, or some other hour or day, e.g. when the brain begins to form (week three), when blastocyst that will be the baby splits to form the placenta and the embryo (week four), when the heart begins to beat (week five), when the embryo begins to move in the womb (week eight), when embryo turns into fetus and begins breathing-like movements (week nine), when the fetus begins to have eye movement (fourteen weeks), when fetus begins to feel pain and suck their thumb (twenty weeks), when fetus begins to dream as evidenced by REM (week twenty-six), or possibly some time before inception, e.g. the second when his father first fell in love, at first sight, with his mother, light (electromagnetic field in 400-700 nm range) being the trigger to surpassing the activation energy barrier to this reaction, which would have occurred on or about the year 1746-47 (pair married on 20 Aug 1748), or alternatively, as Francis Crick intuits, one is never alive at any point in one’s reaction existence?”

    (b) The sperm makes boys tends to be smaller, but quicker; hence it can get to the egg faster, compared to the bigger female sperm, if sex occurs on the day of ovulation or after.
    (c) The sperm that makes girls, tends to be larger; also sperm can stay inside of the woman for three to five days, before ovulation; hence, the bigger female sperm tend to last longer, in the female body, and thereby be in the vicinity when the egg comes out during ovulation.
    (d) Historical studies show that powerful women, who dominate the sex life, tend to make more boys, on average; this being related to the fact that they know or "feel" the day of their ovulation, and thereafter enact the sex act by their choice; were as when men are in control of the "sex life", they will tend to force sex to occur "before" ovulation, the thereby make more females.
