Scientists can take any creature, analyse it, dissect it, list all its chemical parts and write lengthy scientific journals about it, but they can't actually MAKE one, not even something like a simple amoeba..
This excerpt from a scientific website -AMOEBA -"The isolated plasma membrane of Acanthamoeba castellanii consists of approximately 27% lipid, 37% phosphoglycan, and 37% protein. About 60% of the protein migrates as a polypeptide of 15,000 daltons in sodium dodecyl sulfate-acrylamide gel electrophoresis. The phosphoglycan is resolved electrophoretically into two components which migrate ahead of the major polypeptide band. These three components are also detectable upon electrophoretic analysis of whole amoebae and they do not change in concentration when amoeba homogenates are incubated for 6 hours at 25o. These and other controls support the conclusion that the apparently simple macromolecular composition of the amoeba plasma membrane is not an artifact of the isolation procedure. In some preparations actin is associated with the plasma membranes as a nonmembranous component"
