More broadly, the lab explores the implications of challenging categorical thinking in biology, esp. for biological systematics, classification and nomenclature, but lab members are also studying this in the context of tech- and bioethics. It’s a great group and we’re excited to welcome summer RAs!

SPUR RAs will work collaboratively in the lab on our Entangled Linages, Classification, and Individuality project. This examines how the breadth and depth of lineage entanglement impacts concepts of biological individuality, our biological theories, our methodological tools, and biological practice.

Last but not least, my "Biology's Einstein Moment: Specifying Lineal Frames of Reference and Rejecting Absolute Biological History." Name kind of says it all. TL;DR (but read it): specifying frames in reference in biology is super useful and informative:

Biology’s Einstein Moment: Specifying Lineal Frames of Reference and Rejecting Absolute Biological History - Biological Theory
We are currently in the midst of what I call biology’s Einstein moment. This is the rejection of absolute biological history, the idea that there is an invariant, privileged biological history against...

Kate MacCord's "Let’s Talk About Sex…Cell Lineages" revises and updates the epistemic framework of germ that challenges the Weismann barrier.

Let’s Talk About Sex…Cell Lineages - Biological Theory
Sex is fundamental to many organisms. It is through sexual reproduction that humans, and many metazoans (multicellular eukaryotes in the animal kingdom), propagate our species. For more than 150 years...

François Papale's, "The Unit of Selection and the Theory of Evolution by Natural Selection Without Lineage Formation." Unit of selection without reproduction. (Reminiscent of @fbouchard.bsky.social)

The Unit of Selection and the Theory of Evolution by Natural Selection Without Lineage Formation - Biological Theory
The aim of this article is to develop an approach to the unit of selection concept that fits the theory of evolution by natural selection without reproduction. I review the history of the concept to s...

Lucie LaPlane's "Cancer Clones Revised" complicates the way we think about the clonal evolution model of cancer:

Cancer Clones Revised - Biological Theory
Cancers are hard to treat, and this is largely because cancer cells evolve and diversify through space and time, in patients. The study of clonal evolution relies on the study of cancer cell lineages,...

Javier Suárez and Sophie Veigl's, "Vindicating Lineage Eliminativism." Super interesting paper that stakes out a position that challenges a lot of the ways I think about lineages:

Vindicating Lineage Eliminativism - Biological Theory
This article defends a selective eliminativist position with respect to the concept of “biological lineage” as used in certain areas of contemporary evolutionary biology. We argue that its primary epi...

Jim's "Reflection on Taking a Class with Feyerabend" is a wonderful read. Captures his personality and approach as a philosopher. I remember Jim sharing these stories when I was a grad student, and was just passing them along to students in my lab the other day.

Reflection on Taking a Class with Feyerabend
This short reminiscence was written by James Griesemer and e-published for the Paul K. Feyerabend Centennial 1924–2024 (the 100th anniversary of his birth) in a grouping of personal me...

Thanks to @rachelankeny.bsky.social @mikedietrich.bsky.social @sabinaleonelli.bsky.social for putting together this wonderful volume. It's a great set up, each of Jim's papers are introduced by a different friend.
Scaffolding: Selected Contributions of James R. Griesemer to History, Philosophy, and Biology
This book brings together some of Griesemer's most significant contributions for the first time, making it widely accessible in a single collection.

The similarity to other papers is a bit deceptive. [I see you John.]

Or maybe it's not free to access and download? I'm not sure. Regardless, there's a philsci-archive draft in case you can't access the Synthese version:
