 “maybe in the current polarized discussion of identity and sex/gender, people will find the dimensional and empirical approach of this paper a tool to communicate better than the categorical approaches let us do"

Researchers analyzed 102 “just-so” stories shared in online antifeminist spaces. 83% focused on sex differences and rarely acknowledged speculation. The authors call for renewed discussion and reflection on evolutionary hypothesizing. 🔗 www.cambridge.org/core/journal...

Thanks, Ed for the great review. BTW, I agree with Ed, and I have made the same point to Brazilian audiences: LGBTQIA+ rights (and everyone’s rights) should not depend on claims about biology or evolution — human rights stand *regardless* of biological sex or other traits.

Ao completar 9 anos no serviço público como Professor do Magistério Superior, recebo minha progressão funcional para Professor Adjunto 4, o último nível do Adjunto. Em dois anos, poderei fazer promoção para Associado 1 😃

This is objectively true 👇 and is one reason the podcast is well worth your time "Cristina is one of the most well-rounded and intensely fierce intellects in the evolutionary behavioral sciences. She's so charitable and willing to argue in a very positive way"

I couldn't help it but translate it.

In most of the world day-to-day weather variations are still much larger than long-term global warming. As a result, both daily record highs and daily record lows remain common. However as the world warms, new daily record highs consistently far outnumber new daily record lows. 🧪

In my day off...

@siobhancully.bsky.social plenary address: 8 rules for managing patriarchy in the evolutionary behavioral sciences. #HBES2025 @humbehevosoc.bsky.social

1) Siobhan Cully gave #HBES2025 plenary #6 with recommendations on “managing patriarchy in the evolutionary behavioral sciences”. She marshals a range of evidence on the inadequacy of a "male-centered" view of evolution, i.e., that men hunting is the central driver of human life history evolution

2) According to Dr. Cully’s #HBES2025 plenary, men don't exclusively use their caloric surpluses for provisioning, and are often less reliable caregivers. In addition, women's contributions to culture, provisioning, and technology are underrepresented in the archeological record.

Gaming the Metrics? Bibliometric Anomalies and the Integrity Crisis in Global University Rankings “Without reform, rankings may continue incentivizing behaviors that distort scholarly contribution and compromise research integrity” www.biorxiv.org/content/10.1...

New studies show that men with better early-life energetics and faster adolescent maturation had earlier sexual debut and more unrestricted sociosexuality—patterns explained by adult muscle mass. No support was found for adversity-driven “fast” strategies royalsocietypublishing.org/doi/10.1098/...

A comprehensive meta-analysis reveals that 2D:4D ratios differ by sexual orientation. Lesbian women exhibit more male-typical ratios, while gay men show more female-typical ratios. No sig. diffs were found for bisexual individuals. www.frontiersin.org/journals/psy...

Is culture fundamentally different from other ecological processes? A new paper argues culture is an emergent outcome of individual and environmental interactions, best explained by the same ecological and inclusive fitness frameworks used elsewhere. #EvPsych www.sciencedirect.com/science/arti...

The following three things cannot all be true: - Natural selection causes biological traits to tend towards a strong form-function link - The function of human reason is to get closer to truth - Human reason is very prone to straightforward logical fallacy So what gives?
