Children don't look like grownups. Babies don't look like older children. Infants don't look like older babies. Six-month fetuses don't look like infants. Embryos don't look like fetuses.
They are all complete human beings.
I gotta tell ya firebrand, when I hold the photo of an ultrasound taken at four and a half months pregnant, next to a photo of my one week old grandson, I would have to disagree. There is no mistaking that they are the same person. The experience really changed many of my thoughts on these type of issues.
