I saw this anti abortion guy on Twitter insisting that an embryo is an un-fertilized egg.
Then he was shown a pic of an 1.5cm embryo and he call it a fetus.
Just stupidity.
@stueytheround I gave him the facts in a gentle manner. We will see if he responds. ... it's extremely rare that I post in some random thread I found but this guy...I had to say something lol

Apparently in India they use the term "foetus" that early (8 weeks) though we start at 10 weeks. But not sure why he thinks there are unfertilized eggs hanging around the uterus.
@AlphaCentauri cool. The top row is growth on days. 6 day to blastocyst when is when the cells are differentiated, meaning they get the DNA changed to be a skin cell or organ, bone etc
Blastocyst is also when IVF transfers occur.
@ucantstop_me
The interesting thing is that "twinning" can occur up to about 11 days, around the same time as implantation. Prior to that, if you have a 2-cell zygote, you can take the cells apart and get two identical twins, do it again and get quadruplets, etc. After that watershed point, if you divide the cells, they can never replace the function of the lost cells, causing death or massive fetal deformities.
So if the fertilized egg is a fully realized human with a soul, who gets the soul if it becomes twins or triplets?
@ucantstop_me Where the hell do we start with this kind of deliberate ignorance?
"Education" isn't the answer, because they simply don't want to damn well hear the facts. Meanwhile, they spout their ignorance online and even more impressionable minds believe them.
