If this was for a feature story, I'd absolutely ask my editor to commission an illustration. But it's just a short news story, so I have to find something already made...

Let's virtually reconstruct a pelvis, but not create an image of the birthing Neanderthal? I seriously want to commission some pregnant Neanderthal drawings now...

Ah, interesting. Yeah, I only see her face as well. Even a group image that includes a pregnant Neanderthal would be nice, but I can't find that either.

Trying -- and failing -- to find a reconstruction image of a pregnant Neanderthal. Are there none, or am I terrible at searching? πŸ§ͺ🏺

It's Vitamin K, which helps blood clot. Parents are refusing it because "it's a shot" and they don't know enough about human health to understand how to take care of a child.

Hyper- and hypodontia are super common. But extrapolating that to a third set of teeth is like saying that because lots of people have one more/fewer ribs (or vertebrae) we could grow another set. πŸ€”

Uhm. This is an absolutely wild claim (I say as a biological anthropologist). I’d be shocked if theres any research in primates that shows a third set of teeth (or crowns or roots). We did used to have more teeth (an extra 8 premolars to be specific) way back in our evo history.

Vaccine denial sets Americans up for more chronic illness Despite well-established links between pathogens and chronic illness, the U.S. government continues to weaken public health measures to treat and prevent infectious diseases β€” a strategy that will ultimately make Americans even sicker.

Tumaco-Tolita Seated Elder: This 2,000-year-old depiction of an aged man with wrinkles struck fear in people because it held 'the power' Tumaco-Tolita artists were known for their intense realism in sculpting clay representations of humans.

This week’s astonishing artifact is a seated elder figurine from the Tumaco-Tolita people who lived in Colombia/Ecuador two millennia ago. 🏺πŸ§ͺ

To my surprise, CDC is still tracking how many children RFK condemns to measles. Cases are getting younger and, of course, it is spreading faster.

Musk talks about ancient aliens pseudoarchaeological junk, but it's not his only connection to the world of pseudoarchaeology - his racist and antisemitic grandfather, Joshua Haldeman, spent a lot of time in the 1950s searching for an allegedly grand lost city in the Kahalari desert.

Medieval gold ring with dazzling blue gemstone discovered in Norway is a 'fantastically beautiful and rare specimen' The delicate gold ring was made sometime in the Middle Ages and may have belonged to a high-status woman.

Cool medieval ring. Might have helped cure boils (or so they thought). 🏺πŸ§ͺ
