An example of teleology in popular science writing:
"Indeed, considering on the one hand the remarkable permanence of genes, which carry almost without any deviation the properties of a given species through thousands of generations, and on the other hand the comparatively small number of individual atoms that form one gene [we conclude that each separate gene must be built from about one million atoms], one cannot consider it otherwise than as a well-planned structure in which each atom or atomic group sits in its predetermined place."

Examples of teleological statements are included in a document listing a wide range of examples of science analogies, similes, metaphors and the like, drawn from diverse sources, which can be downloaded using this link: 'Creative Comparisons: Making Science Familiar through Language.

It is difficult to tell form a written text such as this whether the teleology (that genes are structures the have been pre-planned) is intended, or simply meant figuratively.
