|...except for being completely wrong!|
a dead chicken, a young oak,
a silk worm spinning dress fabric,
and a very early person
It seems that this concept is a little more difficult than the original author thought.
You can claim that a hen's egg is not a chicken, but you would be incorrect. A fertilized hen's egg contains the complete genetic map and material of a chicken.
You can claim that an acorn is not a tree, but an acorn contains the complete genetic map and material of a tree.
You can claim that a silk worm is not a dress. Finally, you would be correct. A dress is a man-made object. Some are made from silk, but no one in their right mind would confuse a silk worm making silk with a dress because silk doesn't ever become a dress. It only ever becomes the fabric used in the making of a dress. A ball of silk does not grow into a dress in nature, but an acorn grows into a tree and an egg grows into a chicken. This is because an acorn and an egg are, respectively, stages in the development of a mature tree and a mature chicken.
The same is true of a human fetus. It contains the complete genetic map and all the genetic material of a mature human being. It is a stage in the development of a person—same as a child, a young adult, or even an old codger like me. This is not religion. This is science.
