Know thyself
However, the single-celled zygote has the blueprint for the brain, and a "time clock" that determines when the brain will develop. (I find it so amazing that something that is thousands of times smaller than we can see with the naked eye - a single strand of DNA - carries all the information to develop and grow something as complex as a human being - brains, fingernails, corpuscles, rib cage, eardrums, and all.)
No, I'd say that a zygote carries the BLUEPRINT for a brain, within its strand of DNA. There is a built-in timetable, also, which doesn't allow the brain to start until there's actually a place to put it. This stuff is all amazing...
Well said, for you have nuanced all that I have been saying, in a much more coherent fashion. Thank you.
Human life at its most primitive development.
The beginning of the journey of the human person.
