Scientists are making human “embryos” — cell formations that are not viable organisms — from stem cells, but which may be a step before making human organisms.
Even down to the level of molecules and genes, there doesn’t seem to be any physical reason for plants to grow “Golden Ratio” patterns.
Some people keep pretending that we don’t know when human life begins.
Let’s have a little respect here.
Although DNA is involved in specifying the amino acid sequences of proteins, other sources of information are needed to specify the three-dimensional structure of the embryo.
