The article presents a cross-cultural analysis linking the size of a country’s cosmetics market to paternal investment in childcare and to economic inequality. Using a revised sexual selection framework, it suggests that when men contribute more to parenting and when inequality is higher, women may invest in appearance to attract high-investment partners. The study finds that per hour increases in paternal investment relative to maternal investment correspond to about a $2.17 rise in per-capita cosmetics spending.

This work is of interest to psychology because it connects parental effort, mate choice, and social context to consumer behavior, highlighting how cultural and economic factors shape psychological strategies around attractiveness and partnership.

Mitchell et al. reveal the first evidence of chemical mate choice copying in Drosophila. Females exposed to pheromone cues from mated flies prefer males chosen by others, showing that social learning in flies extends beyond visual cues.

Birds in love produce more babies, study shows

“A study finds that birds who freely choose their own mates have 37% more offspring than those which were paired up by researchers in a sort of avian ‘arranged marriage’”

Hi everyone!

I am a Senior Lecturer in #SilwoodPark at #ImperialCollegeLondon. I am interested how social behaviours (#MateChoice, SexualSelection, #sociality) and #LifeHistory traits (#ageing, reproductive traits) evolve in birds. I've also published on #WomenInScience. I use #quantitativegenetics to better understand how #phenotypes are governed by #genetic architecture.

I have too many #pets, I like #hiking, #birding, #moths, and #fungi.

Will follow you back - toot!

Hi Mastodon!

I'm Lars Penke, full professor for Biological Personality Psychology at the University of Göttingen.

I work on the biological foundations of #personality, #intelligence and other individual differences, be it #genetics #hormones #neuroscience or #evolution. I also study the interplay of personality and #social #relationships, especially #matechoice #romantic relationships and #sexuality. I'm interested in #OpenScience and #MetaScience.

Why do so many couples look alike? It is tempting to immediately interpret this pattern of assortative mating as resulting from preferences. This paper gives a very complete review of alternative explanations. #science #biology #matechoice #homogamy #convergence #stratification
