The preprint introduces FGMLab, an open-source educational web application designed to teach biological evolution using Fisher’s geometric model from a trait-based perspective rather than the usual population-genetics/allele-frequency approach. It describes the software as a way to quantitatively illustrate how traits evolve under natural selection, addressing a stated limitation in conventional instruction that emphasizes genotype frequencies without directly showing trait change. The authors do not report any empirical biological results, and they explicitly note the work is a preprint that has not been peer reviewed. The paper does not explicitly discuss endometriosis or adenomyosis; it was included in the corpus via a keyword match in the upstream search index.

Abstract

The process of biological evolution is typically taught through the lens of population genetics, where students are presented with models and diagrams of how alleles (genetic variants) change in frequency over time. While this convention depicts the underlying genetic basis of biological evolution, it fails to quantitatively illustrate how traits, on which natural selection actually acts, evolve. To help teach the process of biological evolution to students, here I present FGMLab, an open source studio application that employs Fisher's geometric model to illustrate evolutionary process from a trait-based perspective.
