I agree with this statement 1000%. If someone tells you not to question something, our natural response should be to question the fuck out of it.
Asking questions should never be taboo, as that’s how new science and new discoveries are made. Questioning the status quo leads to progress, so those who don’t want us to question anything is against progress.
Not being allowed to ask questions isn’t science, its religion. Science should be allowed to stand up to skepticism, or it isn't’ allowed to be science.
The last pro abortion argument is that the heartbeat an embryo has is not a heartbeat at all, but rather electrical signals in cardiac cells.
Let’s ignore that 1) all human hearts consist of cardiac cells and electrical signals and that 2) this claim seems to be first made by a pro choice Facebook post of someone with no medical experience and no sources to this claim as well as a biased WIRED article that also calls the child a blob of cells (very professional!) or a Cut article saying that embryos somehow don’t have hearts at all.
Anyway, according to The Developing Human by Moore et al (10th Edition, 2013) in “Chapter 13: Cardiovascular System”
The cardiovascular system is the first major system to function in the embryo. The primordial heart and vascular system appear in the middle of the third week (Fig. 13-1). This precocious cardiac development occurs because the rapidly growing embryo can no longer satisfy its nutritional and oxygen requirements by diffusion alone. Consequently, there is a need for an efficient method of acquiring oxygen and nutrients from the maternal blood and disposing of carbon dioxide and waste products.
Here’s what the heart looks like at 35 days after fertilization:
As you can see, it already has 4 chambers and is actively pumping blood.
“Initially, three systems of veins are present: the umbilical veins from the chorion, vitelline veins from the umbilical vesicle, and cardinal veins from the body of the embryos.”
Other comments the author made:
“The heart begins to beat at 22 to 23 days (Fig. 13-2).”
“Blood flow begins during the fourth week, and heartbeats can be visualized by Doppler ultrasonography (Fig. 13-3).”
“The initial contractions of the heart are of myogenic origin (in or starting from muscle). … At first, circulation through the primordial heart is an ebb-and-flow type; however, by the end of the fourth week, coordinated contractions of the heart result in unidirectional flow.”
“Partitioning of the AV canal, primordial atrium, ventricle, and outflow tract begins during the middle of the fourth week.”
As you can see, by using vague terms, euphemisms, and not actually defining the meaning of heartbeat, pro abortion advocates are able to blur the science and deny that an embryo is alive. However, the objective truth is that an embryo does have a developing heart by 6-8 weeks.
