This research investigates whether a population of southern African skinks represents a distinct species using genetic and geographic data. Findings suggest river barriers and environmental gradients may drive speciation. By combining phylogenetics and ecological modeling, the study explores how landscape and climate shape biodiversity and species divergence in lizard populations.

This research investigates how Amazonian butterflies evolve their visual systems to match the light conditions of different rainforest niches. By comparing eye and brain structures across many species, it reveals that evolution repeatedly finds the same sensory solutions, showing that adaptation can be surprisingly predictable and may drive the formation of new species.
