The blastocyst IS a mass of undifferentiated cells. At the most, cells might be polarizing, meaning that development pathways are being determined based on their position within the blastocyst--an automatic process completely driven by chemical signals. Differentiated cells actually do not grow, and typically die within a set time after differentiating, depending on tissue type. The process of differentiation is multi-step and continues until death of the organism.
That brings up another point--every tissue within your body, with one exception, has been completely replaced many times through the process of differentiation of new cells to replace the countless cells that die every single day. These new cells come from undifferentiated stem cells present throughout the body. The only exception is the nervous system. The various brain and neural cells do not die and are not replaced by new cells. They are the same cells you were born with, the same cells that started to differentiate three weeks after conception. The only continuity within your body is within the nervous system. You could say that the only purpose of the early embryo is to produce a brain, and the only purpose of the non-nervous system tissues after that is to support the brain.
Here is the Wikipedia article on human fertilization. And here is a figure from that article. Do me a favor, will you, study it and point out or describe to me the physical features of that pre-implantation embryo that enable it to be fully aware of and responsive to its environment through any process more sophisticated than spontaneous chemical responses to chemical and physical signals?
Once again, let me point out that I did not invent the events of early embryogenesis, I have merely described them. And providing accurate descriptions with the intent of educating people does *not* make me a liar or a leftist.
I suspect that we have one of two possibilities here: either you really do not know embryology, or you do know and deceitfully want to define things differently from the way the SCIENCE of Embryology defines things. That second methodology is typical of progressives who try to fashion reality to fit their demonic lusts for exploiting the earliest aged humans.
The blastocyst HAS TO HAVE DIFFERENTIATED ELSE THE CELLS TASKED WITH IMPLANTATION WOULD NOT BE, AS DIFFERENTIATED FROM THE CELLS WHEREIN THE BODY FOR LIFE IN THE AIR WORLD WILL BE BUILT. Even in the morulla stage, differentiation is occurring.
In either case, your assertion as I have quoted it is wrong. If you don't realize why it is wrong, you could study to show thyself approved, or if you do know it is wrong, you are indeed just a common rat liar.
