@kztwyman.bsky.social & @andygardner.bsky.social mathematically connect the dynamics of natural selection to optimisation to provide formal justification for viewing obligately eusocial colonies as adaptive individuals in their own right—that is, superorganism: doi.org/10.1093/jeb/...

Image from the blog showing 5 solutions to countering scientific racism

1. Introduce students to the complexities of developmental processes
2. Introduce students to the complexities of inheritance processes
3. Explain that variation between racialised groups in behavioural and cultural traits is not caused by genetic differences
4. Debunk scientific racism in school and university level science curricula
5. Acknowledge and contextualised the racist histories of academic fields

Unbeatable sex allocation strategy of unconstrained females (r*) as a function of proportion of constrained females (p) under local mate competition with two foundresses colonising the patch. Shown are the result for Godfray’s (1990) erroneous diploidy solution (dashed grey line), our corrected diploidy solution (solid grey line), and our haplodiploidy solution (solid black line). Overlaid are results from individual-based simulations (discs).
