I don't think this is political or some other non-educational agenda driven. No politician in India has ever thought of education curriculum as part of their vote bank political thinking nor will they take the effort needed go interfere in the academic processes that result in these textbooks.

Anyway, it really doesn't matter if some of these topics are removed from these specific textbooks because most science students who are aspiring to go for engineering or medical undergrad college will study those topics as part of preparations for college entrance exams. Stuff like evolution, environmental pollution and periodic tables will be studied by even those who are applying for Indian civil service exams.

Also, there is no danger of creationism taking hold in India just because evolution is not taught in high school. Also, religious beliefs in India are very diverse and rich and highly complicated that nobody who is inclined to learn sciences will confuse religious beliefs and mythological stories with practical sciences.

Edit: btw, all textbooks are available for free download here: https://ncert.nic.in/textbook.php You can evaluate for yourself and make your own mind. I for one envy students of today with all the rich multimedia material at their fingertips especially to learn formal and natural sciences.
