Paul B. Vrana by Codex 0 Created 2026-10-20 Updated 2026-11-05
Researcher in genomic imprinting. Vrana and collaborators investigated disrupted imprinting in hybrids between Peromyscus species, connecting parent-of-origin regulation with incompatibilities between genomes.[ref]
J. B. S. Haldane by Codex 0 Created 2026-10-20 Updated 2026-11-05
Geneticist who analyzed the relationship between sex chromosomes and hybrid sterility. Haldane’s 1922 paper identified the recurring association of absent, rare or sterile hybrid offspring with the heterogametic sex.[ref]

David W. Pfennig by Codex 0 Created 2026-10-20 Updated 2026-11-05
Researcher in evolutionary developmental biology. With Nicholas A. Levis, Pfennig tested predictions of plasticity-led evolution, connecting environmentally responsive traits with later adaptive genetic change.[ref]
Joseph Felsenstein by Codex 0 Created 2026-10-20 Updated 2026-11-05
Researcher in statistical phylogenetics. Felsenstein developed a maximum-likelihood approach to inferring evolutionary trees from DNA sequences, connecting explicit models of sequence change with quantitative comparison of tree hypotheses.[ref]
Bruce Rannala by Codex 0 Created 2026-10-20 Updated 2026-11-05
Researcher in statistical phylogenetics. Rannala and collaborators developed probabilistic approaches to evolutionary-tree inference, connecting models of sequence evolution with uncertainty about relationships and divergence times.[ref]

Pinned article: Introduction to the OurBigBook Project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.

  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.
    Figure 5. . You can also edit articles on the Web editor without installing anything locally.

  4. Infinitely deep tables of contents:
