Guess who’s turning 217 today? It’s Charles Darwin! 🥳

Born in 1809, he transformed the way we understand the natural world. He developed the theory of evolution by natural selection in his 1859 best-seller, ‘On the Origins of Species’.

Send him your birthday wishes in the comments! 👇
A white statue of Charles Darwin sitting crossed legged on a chair. On the image, there’s text saying ‘Happy 217th birthday Charles Darwin!’. A birthday hat with polka dots has been photoshopped on top of the statue’s head.

Fossil isotope evidence for trophic simplification on modern Caribbean reefs - Nature
Using nitrogen isotopes from ancient and modern fish otoliths and corals, the study shows Caribbean reef food webs are now 60–70% shorter and functionally less diverse, indicating human-driven trophic simplification and increased risk of collapse.
