If you want hot takes about fertility decline, my money's on this one
The famous New Yorker cartoon by Tom Toro showing a man in a threadbare suit telling children sitting around a fire "yes, the planet got destroyed but for a beautiful moment in time we created a lot of value for shareholders" edited to read
"yes fertility has collapsed, but for a beautiful moment in time we created a lot of value for shareholders"

Animals are known to prefer kin as social partners. But non-kin bonds are surprisingly common too. So, who forms them, how stable are they & what drives them? In our new @animbehsociety.bsky.social paper we tackle these overlooked questions in free-living rhesus macaques: tinyurl.com/mwsbkjve (1/5)

Question: do I know anyone near Nantes who would be willing to pick up a dead gull-billed tern and its logger? L49 has sadly been killed near a road. I’d be very grateful for a picture and the logger and would of course reimburse postage.

Primate Profiles #49: Guianan Red Howler The only record of "tool use" by these monkeys (according to the book I'm currently using) is an adult male hitting a sloth with a large stick. A monkey with a big brain, but maybe questionable morals? 🐒 Image: @fernandofariasbirding (iNat.org)
Red howler monkey walking along a branch with tail in the air. These monkeys are reddish-chestnut all over, with grey facial skin. Their tails are long and prehensile. They have a large throat pouch which helps with their very loud howling calls.

1/2 Adult play Although phylogeny predicts which primates play as adults (if play exists in one species, it is more likely to exist in close ones), it is whether or not the society is tolerant (and not despotic) that best predicts this behavior (paper) royalsocietypublishing.org/rsbl/article...

We have a new paper: "intergenerational conflict among females may play a role in the evolution of #chimpanzee #menopause" royalsocietypublishing.org/doi/10.1…
Two of the scientific graphs from the linked paper. The left side shows that as female chimpanzees get older, their relatedness to the males in their community increases because they now include their sons. The relatedness to other females however stays low, because new unrelated females constantly join the community. The graph on the right shows that these age-related changes in relatedness mean that females are expected to act selfish when they are young, but care about others in the group when they are older.
