Critics of persistence studies argue the pitfalls of the approach lie in a failure to recognize institutional change ("anti-persistence"), vague mechanisms, the insufficient use (or misuse) of historical sources and narratives, the compression of history, and a failure to account for the effects of geography."

Preformationism – the theory that all organisms have existed since the beginning of life, and that gametes contain a miniature but complete preformed individual, and in the case of humans, a homunculus. No support when microscopy became available. Rendered obsolete by cytology, discovery of DNA, and atomic theory.
For example, zoology is the study of animals, while botany is the study of plants. Other life sciences focus on aspects common to all or many life forms, such as anatomy and genetics. Some focus on the micro-scale (e.g. molecular biology, biochemistry) other on larger scales (e.g. cytology, immunology, ethology, pharmacy, ecology). Another ...
In the case of acceptance of evolution in the years after Darwin's On the Origin of Species, age was a minor factor. [2] On a more specialized scale, it also was a weak factor in accepting cliometrics. [8] A study of when different geologists accepted plate tectonics found that older scientists actually adopted it sooner than younger scientists ...
Homochirality is an obvious characteristic of life on Earth, yet extraterrestrial samples contain largely racemic compounds. [7] It is not known whether homochirality existed before life, whether the building blocks of life must have this particular chirality, or whether life must be homochiral at all.
