Reading the source that Nature cites, it seems like the content has been made temporarily unexaminable ‘in light of COVID’, rather than the section actually getting cut from the textbook. https://ncert.nic.in/rationalised-content.php Could any Indian with a new physical textbook perhaps confirm? It’s a rather concerning policy.

The headline also seems awfully clickbaity. What the policy seems to have done is shifted basic evolution down to younger grades and moved the more advanced concepts to more senior grades. However, this shifts more advanced concepts up to grades in which science as a subject is not compulsory. Regressive as this is, this isn’t what the headline suggests.
