Scientific Epistemology & Policy


Curating beyond the natural

Natural history museums should consider expanding their mission by intensively collecting and curating domesticated, hemerophilic, and genetically engineered animals, plants, and fungi to improve the study of evolutionary biology and anthropology, as well as mitigate against future climatic and economic challenges.

Reconsidering publication policy

What do reproducibility and accessibility mean in science? The best way to ensure long-term survival of data on extinct organisms is to collect and disseminate the data while it is currently available, before it is too late. In contrast, ignoring known specimens constitutes data falsification.

Keratin proteins? Replication vs. Validation

Antibody stains used to identify keratin protein in fossils might be adhering to substances other than keratin. Repeating the method does not always provide additional insight. Instead, triangulating results with other methods suggests that proteins do not preserve in Mesozoic fossils. Organic fossil feathers are preserved via more stable melanin pigment.
