Parasite quantity and quality are uncoupled determinants of transmission heterogeneity
Silva et al. deconstruct parasite transmission into stages and show that performance at any one stage is uncorrelated with performance at other stages. This has important implications for attempts to ...

Page of the Centre for Logic and Philosophy of Science, KU Leuven, announcing two upcoming talks on October 3, 2026 (14:00-16:00). Talk 1 Speaker: Juncheng Tao Abstract Evolved selfishness has been offered as a risk factor for AI safety. The concern is that if AI systems undergo Darwinian evolution, this will lead to selfishness, which will harm humans. To assess this concern, we consider (1) if AI systems can truly evolve, (2) what selfishness is, (3) whether evolution leads to selfishness, and (4) whether AI selfishness is bad for humans. We conclude that selfishness is not the reason evolutionary AI is dangerous. Instead, the true danger of evolutionary AI lies in what we are calling niche prospecting, which involves these systems exploring the space of possible niches. Talk 2 Speaker: Alejandro Fábregas-Tejeda Niche construction theorists standardly understand niche construction to occur through organisms modifying their selection regimes. Niche construction is also commonly characterized as organisms playing an active role in the evolution of their species. In this article, we argue that these characterizations do not amount to the same thing. Organisms can take an active role in the evolution of their species without changing their selection regimes. This article describes all the ways organisms can do so. The result is a 3x3 matrix detailing all nine forms of niche construction.
