Feeling down today ? Why don’t you just go to the lab and perform some destructive analysis on subfossil scallop from a Neolithic shell midden ?

17/ So, this Nobel week, we celebrate the lights of science, the crowning of intellectual ascent.
But remember: wisdom isn’t always found in cozy halls, nor genius in a calm laboratory. Sometimes it walks through Bakhmut’s fields, with a pen, convictions, and hope not to become what it hates.

16/ He was born in 1993, just two years after me. Though our academic fields differed, we shared the same bedside books.
He sharpened his ideals in the harsh reality of the world, while I moved within one of the most protected social categories.
And now, only one of us lives to continue.

15/ Osievsky did not hate. He deplored how war sanctifies hatred. In homage to his friend the Russian anarchist Dmitry Petrov, also an anarchist anthropologist killed while fighting for Ukraine, he wrote: “We did not choose this history. We have only ourselves and the freedom not to become monsters”

14/ discussing the disastrous political misuse of genetic concepts, filling pages of his notebook he always kept close. He doubted determinism, biological or historical. He believed in freedom, not as a grand universal, but as lived, fragile, always threatened by circumstance, ideology, violence.

11/ And I can't help but draw a parallel between the conditions under which he and I read the same books: classical Greek history, Graeber, Latour, Clastres... It reminds me of Konrad Lorenz studying fleas behavior on his own skin while held as a prisoner by the Soviets.

8/ This constant analysis was not mere academic exercise but tied to a strong political commitment: leftist, feminist, vegan, anarchist. Evheny participated in the Maidan protests from 2014 and was involved in Ukraine’s Social Movement.
![The Social Movement (Ukrainian: Соціальний рух, romanized: Sotsialnyi rukh;[a] abbreviated SR) is a Ukrainian left-wing community organization founded in 2015, which stands on the principles of democratic socialism, opposing capitalism and xenophobia.](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:estv6ozzvjyzz526rtb7ln7f/bafkreibjcdjabnmbmwrre7jeyimf7tmpukeiqaj7xnumkzs2aujjixev5u@jpeg)

4/ His master’s thesis already focused on the John Frum cargo cult in Tanna, Vanuatu, but at the dawn of his academic career, he had published widely on a stunningly diverse range of subjects: Foucauldian behavioral economics, Melanesian ethnography, cycad ethnobotany...

2/ Evheny Osievsky was one of them. He died near Bakhmut, killed by shellfire on May 22, 2023, while serving as a volunteer rifleman-medic in the 77th Air Assault Brigade. His body was identified not by uniform or papers, but by a vegan tattoo on his wrist and a cinema magazine in his pocket.

1/ It is Nobel week: the giants of world science gather beneath gilded halls of leading global institutions.
But what about those whose approach to knowledge is radically different? Those who base their science on lived experience, fragments from human worlds, often silent or marginal ?

For #FossilFriday, meet Inoceramus : the largest bivalve to ever exist. This genus lived in the Cretaceous seas of North America and Europe.
This one is 178 cm long. And look at these rings ! It must an amazing palaeoenvironmental recorder to work with 😍
