None of your quotes indicate that it would be impossible to implant these. The article is beating around the bush, but essentially it is saying "These could potentially be implanted." That's why people are somewhat up in arms about this. Read the other article I linked.

This research in animals has led to successful implantation, but not live births. Nobody knows why yet.

Nothing I said had anything to do with if these were viable or could be made viable, just that they aren’t direct equivalents.

People could be up in arms if hypothetically 50% of these where viable, but the nonviable 50% would still cause errors when compared to human embryos. Alternatively, 100% could be viable and they could still be different in critical ways from natural human embryos resulting in universally late or premature births etc. Or perhaps 0% are viable and people just don’t understand the nuances.

It’s therefore an orthogonal question.

You don’t appear to be able to say anything helpful about what “model” means in this discussion. The only explicit claim you made (that they were different because they would have been implanted in a womb for a week already) was incorrect. Some would likely have been implanted for a day.

Your timeline is off, the egg can take nearly 2 weeks to implant but that requires a delay in fertilization. This 14 day timeline is specifically in reference to fertilization not the release of the egg.

The discrepancy exists because people can track the day of ovulation and hormonal changes from implantation but actual fertilization has no obvious signs, unless your doing IVF or something and looking at the actual egg.

That said, extreme outliers may exist but that’s not what we’re talking about.
