Heredity as transmission of information: Butlerian 'Intelligent Design.'.
In the 1870s, Ewald Hering and Samuel Butler provided what was, for that time, a scientifically coherent foundation for the Lamarckist view that positive adaptations to the environment acquired during an individual's lifetime can be transmitted to the offspring. Observing that heredity was a form of memory (involving stored information), they distinguished what are now known as genotype and phenotype and proposed that cognitive abilities present in the the most elementary organisms might mediate a transmission of acquired adaptations. While compatible with the then-available facts of evolution, this Butlerian version of 'intelligent design' was rendered less credible by subsequent appreciations of the discrete (discontinuous) inheritance of many phenotypic characters (Mendelism) and of the separation of germ line from soma (Weismanism). However, it can now be seen that 21st-century bioinformatics has 19th-century roots.
