Past Records, Current Challenges: Integrating Paleoclimatic and Geographical Controls into Macroevolutionary Models

Résumé

As phylogenetic, biogeographic, and diversification models become increasingly sophisticated in their computational design, they also achieve greater biological realism. This growing complexity is largely driven-and enriched-by the integration of paleontological, paleogeographic, and paleoclimatic data, which is not only essential for accurate inference but also represents one of the most promising frontiers in macroevolutionary research. Integrating past landmass configurations, climatic shifts, and paleontological evidence offers a more complete framework for understanding lineage divergence and extinction. By including these historical factors, phylogenetic models can more accurately estimate divergence times, infer ancestral ranges, and reveal the ecological and evolutionary forces that shape biodiversity. In turn, these reconstructions shed light on past geological events-such as the emergence of geographic barriers or the timing of major climatic transitions. The BioGeoPhylo Workshop In Arles (March 26-28th, 2025) brought together 50 biologists, geologists, and paleontologists working at the intersection of Earth and Life Sciences to identify the key challenges in integrating these disciplines. Cutting-edge presentations were followed by discussions and a broad brainstorming session aimed at proposing future research directions and identifying obstacles to overcome and how to incorporate these factors into macroevolutionary models.
