New paper: "Kin competition drives the evolution of earlier metamorphosis", with Bing Dong (Open Access):

https://doi.org/10.1002/ece3.70806

Figure 1 from the paper. The legend reads as follows:

Juveniles that undergo metamorphosis earlier accrue less resource and hence enjoy only limited reproductive success as adults, whereas juveniles that undergo metamorphosis later accrue more resource and hence enjoy greater reproductive success as adults, but juveniles that do not undergo metamorphosis before a catastrophe strikes their natal patch are killed and have zero reproductive success. Moreover, to the extent that there is competition for resources, juveniles that undergo earlier metamorphosis free-up resources for their patch mates—to whom they may be genetically related.

Rock art at Cueva de las Manos, Santa Cruz Province. From Wikipedia: "Cueva de las Manos (Spanish for Cave of the Hands or Cave of Hands) is a cave and complex of rock art sites in the province of Santa Cruz, Argentina, 163 km (101 mi) south of the town of Perito Moreno. It is named for the hundreds of paintings of hands stenciled, in multiple collages, on the rock walls."

New paper: "A geometric approach to the evolution of altruism" (Open Access)

https://sciencedirect.com/science/article/pii/S0022519323002503

Altruism alleles are disfavoured upon their first appearance in the population, when they are not yet shared by kin. This slows the evolution of altruism.

A figure from the paper, showing the probability of fixation for alleles of different effect sizes in altruism versus nonsocial scenarios.
