17+
In silico evolution instantiates the processes of heredity, variation, and differential reproductive success (the three "ingredients" for evolution by natural selection) within digital populations of computational agents.
18+
Consequently, these populations undergo evolution, and can be used as virtual model systems for studying evolutionary dynamics.
19+
This experimental paradigm --- used across biological modeling, artificial life, and evolutionary computation --- complements research done using in vitro and in vivo systems by enabling the user to conduct experiments that would be impossible in the lab or field [@dolsonDigitalEvolutionEcology2021].
20+
One key benefit is complete, exact observability.
21+
For example, it is possible to perfectly record the full set of parent-child relationships over the history of a population, yielding precise and accurate phylogenies (ancestry trees).
22+
This information reveals the sequences of events behind gain, loss, or maintenance of specific traits, and also facilitates making inferences about the underlying evolutionary dynamics of a given system.
23+
24+
The Phylotrack project provides libraries for tracking and analyzing phylogenies in in silico evolution.
25+
The project is composed of 1) Phylotracklib: a header-only C++ library, developed under the umbrella of the Empirical project, and 2) Phylotrackpy: a Python wrapper around Phylotracklib, created with Pybind11.
26+
Both components supply a public-facing API to attach phylogenetic tracking to digital evolution systems, as well as a stand-alone interface for measuring a variety of popular phylogenetic topology metrics.
27+
The underlying algorithm design prioritizes efficiency, allowing Phylotrack to support large agent populations with rapid generational turnover.
28+
The underlying C++ implementation ensures fast, memory-efficient performance, with multiple explicit features (e.g., phylogeny pruning and abstraction, etc.) for reducing the memory footprint of phylogenetic information.
