I often hear or read this statement:
"It's not a human, it's a fetus."
In other words, some think a fetus is non-human until a certain point.
And another similar statement:
"The fetus isn't alive until 26 weeks of gestation."
So some think the fetus is not actually "alive" until a certain point.
What does biology have to say about these two statements?
I encounter these statements often in discussions about abortion, but that issue, and other similar philosophical issues, are outside this question. I'm wondering strictly from a scientific/biological standpoint: are these statements true?
Is the fetus in a human mother non-human until a certain point?
Does the fetus not classify as "alive" until a certain point?
The people I encountered truly believed these statements (3 of the 4 in mind also claimed science was on their side), so it's not as if the question has no merit. I assumed that in the realm of science and biology, there must be a convincing and sure answer.
