Plot showing simulated energy balance (production - consumption) across the lifespan of a hunter-gatherer family. Left plot, which includes child food contributions shows simulated trajectories that dip below and then above 0. Right plot, which includes only food produced by the wife and husband, shows chronic energy deficits.

Inspired by the work of @lallailaria.bsky.social, @sheinalew.bsky.social, @jeremykoster.bsky.social & many others, I've simulated hunter-gather family energy balance across the lifespan. If kids contribute, families can (barely) maintain energy balance, but if they don't, it's impossible 🧪 #BioAnth

The NSF Bio Anthro Program DDRIG, Cultural Anthrpology DDRIG, and Archaeology DDRIG have all been archived (as of yesterday afternoon). Please speak with your grad students and plan accordingly. To say I am angry and depressed about this is an understatement.

Such a cool paper. And, fascinating to think about in the context of aging organisms that compensate for deteriorating abilities with age and *thrive*

i keep getting told that woke students don't want to be challenged by hard ideas but whenever i spend time with actual college students i find that the opposite is true

All together now: chimps engage in contagious peeing If one animal urinates, others are likely follow, according to a study of captive apes.

The closer a chimp is to the first urinator, the more likely it is to follow suit

Stress responsiveness in a wild primate predicts survival across an extreme El Niño drought White-faced capuchins with a stronger stress response to previous droughts were more likely to survive a severe El Niño drought.

Menopause research is globally underfunded. It’s time to change that Nature asked the world’s largest health-research funders what they are doing to study a life stage experienced by half of humanity. Here is what some of them told us.

Menopause will be experienced by half of humanity, but it has rarely been a priority for health systems or research

No evidence of reproductive senescence within the natural lifespan in resident mountain chickadees (Poecile gambeli) - Behavioral Ecology and Sociobiology Reproductive aging in vertebrates is commonly characterized by an increase in reproductive performance early in life and a decline in reproductive performance late in life (i.e. senescence). However, ...

Extreme longevity may be the rule not the exception in Balaenid whales Whale life spans have likely been greatly underestimated.

What do we begin to discover about animals when humans are removed from the picture?

"...all balaenid and perhaps most great whales have an unrecognized potential for great longevity that has been masked by the demographic disruptions of industrial whaling."

I wrote a story about some of the earliest modern humans to arrive in Europe. The LRJ culture, which dates to about 45,000 years ago, left fossils that contain DNA. And that DNA has a lot to say about modern humans in general. [Gift link] nyti.ms/4gAngzp 1/2
