The proposal that a human sperm contained a miniature human being is consistent with the now-discredited theory of development known as preformation theory.
Preformation theory, a historically well-liked belief that creatures develop from miniature replicas of themselves, has a long history in biology. Preformationists thought that the shape of living things already existed in reality before their growth, as opposed to being put together from components.
Hippocrates and Anaxagoras were the first thinkers to put forth a preformation theory, with Hippocrates proposing that the zygote contains all of the adult's structural components and Anaxagoras asserting that the paternal semen contains all of the child's components.

Polysaccharides are present in all living organisms where they carry out one or more of their diverse functions. While there is no specific category or definition of a complex polysaccharide, most are structurally complex. Polysaccharides contain 1–5 different monosaccharide (sugar) units. The different sugar units may have different anomeric configurations and/or be joined by different glycosidic linkages. Polysaccharides may be linear or branched. Branches may be short saccharide units on a linear backbone or the molecule may have a branch-on-branch structure; in either case, the branches may be isolated or clustered. Polysaccharides may contain non‐carbohydrate groups. Esters or cyclic acetal groups, when present, can be removed by appropriate treatments. All polysaccharides are polydisperse, i. e., are present in a range of molecular weights rather than having a single molecular weight
