@HumBehEvoSoc It is an enormous honor to receive this award, I'm grateful for everything HBES is doing for behavioral science, and I'm committed to following their lead and continue with evolutionary behavioral research over here in Brazil, and in any other place.

Fraternal birth order and maternal fertility hypotheses are not always clearly supported. Honored to have participated in this contribution

Using budgeted mate design task, we found that people value intelligence in their ideal partners more than other traits. Typical sex differences were observed mostly within the heterosexual group. https://t.co/xWukhTpHCd

1. What do we know about hunter-gatherers (HG)? This is the go-to book, first published in 1995, w/ a 2nd edition in 2013. Here's an overview of the book that I hope will encourage @NPR, @sciam, & others to consult it when reporting on & evaluating the import of new HG studies 🧵

"the ancestral social organization of primates was inferred to be variable, with the most common social organization being pair-living but with approximately 10 to 20% of social units of the ancestral population deviating from this pattern by being solitary living."

Distinctiveness negatively affects the perception of attractiveness in both sexes across all studied populations; femininity increased female facial attractiveness, but there is no effect of masculinity on male facial attractiveness & NO EFFECT OF SYMMETRY on attractiveness!

Happy to have been part of this project led by Karel Kleisner & Petr Tureček. 'Distinctiveness and femininity, rather than symmetry and masculinity, affect facial attractiveness across the world'

When interested in someone, women report more “I was laughing at the jokes of someone I cared about”, while men report more frequently “I was buying gifts for someone I was interested in”

[Andrew G. Thomas @DrThomasAG]

Our new paper out in Personal Relationships (w/ @mapostolou4 @CostelloWilliam @paulawright @jarkaVarella @varella_marco).

What do people do to try to become a more desirable mate? And does this differ by country?

We found two main strategies types:
> Strategies demonstrate desirable traits
> Strategies hiding or misleading about their undesirable traits

And surprising cross-cultural similarity!

Evolutionary medicine identifies 6 reasons why our bodies are vulnerable to disease. They are: 1) defences, 2) environmental mismatch, 3) trade-offs, 4) conflict between survival and reproduction, 5) co-evolution with infectious parasites and 6) constraints on natural selection

We had a great time during ISHE Summer Institute at one of the 3 locations organized by @ISHE_society, and hosted by @ulyssesUpa & his team in Recife, Brazil. Six workshops, 3 plenary talks, around 60 posters, great food, and a boat trip! Thank you all https://t.co/9nFbKERZfC

Brazil has a well-trained and rising cohort of evolutionary scientists who, no doubt, are the future of the field. In this chapter… 1/4
