What is fossilsim?

A fossil-record simulator that quietly grew a trait-evolution engine.

FossilSim is a mature R package for simulating fossil records on phylogenetic trees, and its release cadence reflects that: long gaps punctuated by a single capability addition. The last four releases span three years, with the most recent being a compatibility sync to its companion Shiny front-end rather than new functionality. The core simulation surface has been stable since 2022.

What is MotherDuck?

MotherDuck keeps wrapping its agent-native stack in the plumbing enterprises need to adopt it.

The two capabilities MotherDuck has bet on — Flights for Python pipelines that MCP agents can drive, and Guides for the organizational context those agents read automatically — are now surrounded by the operational layer that makes them usable at scale: RBAC, org-wide admin visibility, regional availability in Sydney and Tokyo, runtime limits. The August 14 release adds the client surface that was still missing, a CLI covering auth, queries, Dives and Flights with scriptable output.

A fossil-record simulator that quietly grew a trait-evolution engine.

◆ Current state

FossilSim is a mature R package for simulating fossil records on phylogenetic trees, and its release cadence reflects that: long gaps punctuated by a single capability addition. The last four releases span three years, with the most recent being a compatibility sync to its companion Shiny front-end rather than new functionality. The core simulation surface has been stable since 2022.

◆ Where it's heading

The arc runs from sampling mechanics toward simulating what the organisms actually were. Version 2.2.0 taught the package to handle occurrence data for occurrence birth-death models; 2.3.0 then added trait simulation under Mk, BM and OU, which is a different kind of output than fossil ages. Since then the work has been maintenance and keeping the FossilSimShiny GUI in step, suggesting the authors consider the current model set feature-complete.

◆ Prediction

The pairing of the 2.3.3 release with a FossilSimShiny version bump points to the GUI, not the library, as where the next visible work lands. The entries do not show enough activity to predict a specific new model family.

MotherDuck keeps wrapping its agent-native stack in the plumbing enterprises need to adopt it.

◆ Current state

The two capabilities MotherDuck has bet on — Flights for Python pipelines that MCP agents can drive, and Guides for the organizational context those agents read automatically — are now surrounded by the operational layer that makes them usable at scale: RBAC, org-wide admin visibility, regional availability in Sydney and Tokyo, runtime limits. The August 14 release adds the client surface that was still missing, a CLI covering auth, queries, Dives and Flights with scriptable output.

◆ Where it's heading

The pattern is consistent: ship an agent-facing capability, then spend the following weeks making it governable and reachable. Iceberg interoperability keeps widening — Databricks-managed tables, Cloudflare R2 as a persisted catalog, server-side attach — which positions MotherDuck as a compute engine over catalogs it does not own. The CLI extends the same logic to automation: anything the UI can do should be drivable from a script or a CI job.

◆ Prediction

Expect the CLI to leave preview with Flights and Dives management as its centre of gravity, and Guides to follow the same governance path Flights took — org-level controls, roles, and visibility rules layered on after the capability lands.
