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 treespace?

treespace ships once every year or two, and only when CRAN or a user forces it.

treespace explores and compares sets of phylogenetic and transmission trees, including the tree-distance measures used in outbreak reconstruction. Its release history is entirely reactive: five updates across five years, each triggered by a CRAN policy change, an upstream package removal, or a bug someone reported. The most recent is an Rd cross-reference format patch plus a maintainer email change.

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.

treespace ships once every year or two, and only when CRAN or a user forces it.

◆ Current state

treespace explores and compares sets of phylogenetic and transmission trees, including the tree-distance measures used in outbreak reconstruction. Its release history is entirely reactive: five updates across five years, each triggered by a CRAN policy change, an upstream package removal, or a bug someone reported. The most recent is an Rd cross-reference format patch plus a maintainer email change.

◆ Where it's heading

The package is stable and lightly staffed rather than abandoned — bugs that affect correctness do get fixed, and CRAN deadlines are met. But the 2023 update is the telling one: rather than vendor or replace adephylo when it faced removal, the maintainers disabled two tree-vector methods and marked the loss as hopefully temporary. Two years on, nothing in the feed indicates they came back.

◆ Prediction

The next entry will most likely be another CRAN-compliance patch, on the pattern of four of the last five releases. Whether the Abouheif and sumDD methods ever return is not something these entries give any signal on.

Frequently asked questions

What is the difference between fossilsim and treespace?

Both compete on the same themes — phylogenetics — within Analytics. fossilsim and treespace are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band). See the at-a-glance table above for a side-by-side breakdown of velocity, recent sparks, and editorial themes.

Is fossilsim better than treespace?

Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. fossilsim and treespace are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
