Stop asking people when they “believe” that an individual human life begins and start asking if they KNOW and are using the objective science to derive legitimate positions and determine valid public policies and laws.

.@jaketapper: When do you think life begins?
@GovernorBullock: “It’s not up to people like me to be making these decisions. I think that’s the greater point. It’s ‘what does an individual woman need to do with her body and with her health care?’” #CNNSOTU
The New Yorker’s Dangerous Ambiguity About When Life Begins
Our founder’s latest editorial @realDailyWire.
dailywire.com/news/the-new-y…
This is not new.
The New Yorker is recycling what abortion advocates have sold for 50+ years: that a woman can be “almost pregnant.” It worked before.
That is why so many people today think pregnancy begins at implantation.
They are doing it again.

Pregnancy tests draw a misleading, somewhat arbitrary, binary between a state of being pregnant and not being pregnant. You can be kind of pregnant, a little bit pregnant, or almost pregnant, or maybe pregnant, and still test positive for pregnancy. Pregnancy tests, particularly at-home urine tests, capture a moment in time at which an embryo has implanted and is interfacing with the uterus in some way. “We define how we understand the beginning of pregnancy based on this snapshot, but such a freeze-frame contains limited information,” Apoorva Tadepalli writes.

A human embryo = a human being
In human sexual reproduction (in vivo), scientifically, a woman is “pregnant” and pregnancy begins when the new human being begins to exist.

Actually, EPF is believed to be the earliest possible marker of pregnancy.
PREGNANCY CAN BE CONFIRMED before implantation, 12 to 24 HOURS AFTER FERTILIZATION (when a human being begins to exist) by detecting a protein called “early pregnancy factor” or EPF in the mother’s serum (blood plasma), AND the detection of this protein indicates a viable human embryo/human being exists.

“Louisiana v. FDA thus epitomizes a profound national estrangement from biological and moral reality.”

“As we descend into an instrumental use of human life, we destroy the very reason for which we were undertaking our new therapies; we degrade the humanity we were trying to heal.”

PSA: Considering human sexual reproduction, fertilization is when a human life starts and
"personhood" begins—not
"consciousness," or some other point that conveniently fits a particular narrative.
📣 GOOD NEWS: HB 1071 passed the Florida House. The bill explicitly addresses the human life cycle to ensure Florida students (grades 6-12) are learning about their own development (one of the most remarkable phenomena in science).

A friend was researching a new Florida education bill that (among other things) requires some basic, scientifically accurate human embryology education, and Google flagged the human life cycle as a “controversial provision.” 👇🤔

“And while Vance may know, the administration’s overarching indifference reflects a failure to fully grasp scientific reality about humankind.”

“HHS is a science-focused organization, and human subjects research protections should, at a minimum, incorporate scientifically accurate definitions of the human being.”

Yes!!
We have two beautiful, scientifically accurate children’s books that celebrate human life.

This beautiful children's book from @ContendProjects is a wonderful gift to give this Christmas!

As noted for centuries, "A small error in the beginning leads to a multitude of errors in the end."
Erroneous ideas about when a human being begins to exist lead to dehumanizing and destructive philosophical, ethical, and legal concepts about humankind.
"The fertility rate in the U.S. dropped to an all-time low in 2024 with fewer than 1.6 children being born per woman," federal data released by @CDCgov shows. cbsnews.com/news/us-birth-ra…

All human beings are persons, and this should be the starting point for relevant public policies and laws.

Yesterday’s WSJ headline “Bill Would Force Hospitals to Warn if They Can’t Save Babies” is bizarrely framed.
Ensuring parents know which hospitals provide life-saving care for infants—or human beings at any stage—is fundamental to healthcare.

There is absolutely no question whatsoever, that, considering human sexual reproduction, the life of every human being begins at fertilization.
-C. Ward Kischer, Ph.D.
*Emeritus prof. of Cell Biology & Anatomy, specialty in Human Embryology
The scientifically accurate term for HUMAN sexual REPRODUCTION is FERTILIZATION .
All sexually reproduced HUMAN BEINGS begin to EXIST at FERTILIZATION (commonly referred to as “conception”).

“A human life starts when two special cells-one from a female human being and one from a male human being-make contact and fuse together.
The scientific name for this process is FERTILIZATION.”

Check out some of the false definitions from Advocates for Youth’s “Reproduction Basics” sex education lesson.
No wonder nearly 40 percent of young adults believe a human life begins at birth!
