Encephalization – Meaning, Pattern in Human Evolution & Biological Significance
While an increase in body size results in an increase in brain size, the brain:body ratio decreases in larger animals. Body mass increases disproportionately to an increase in brain mass as most tasks only require a fixed brain capacity. While there is a correlation between body size and brain size, there is not a correlation between brain size and intelligence

Why dentition is so important for studying primate & human evolution?
Teeth = critical fossils: preserved, diagnostic for taxonomy, diet, development and behavior. Y-5 pattern = hallmark of hominoids (apes + humans) — five cusps with Y-shaped central fissure; indicates mixed diet and ape affinity.

ICDS AT 50
ICDS at 50 symbolizes India’s unwavering commitment to child and maternal well-being. Yet, to remain relevant in the next fifty years, ICDS must evolve into a nutrition-cum-learning ecosystem aligned with global standards, NEP 2020, and Viksit Bharat 2047. Strengthening Anganwadis, professionalising the workforce, modernising infrastructure, and embracing data-led governance will ensure that ICDS continues to nourish India's future generations.

FLEXIBLE INFLATION TARGETING
Flexible Inflation Targeting has contributed significantly to anchoring inflation expectations in India. While the 4% target and ±2% band appear broadly appropriate, stronger commitment to headline inflation metrics and fiscal discipline is essential. A well-calibrated FIT framework, paired with credible fiscal consolidation, will ensure India’s sustained growth and macroeconomic resilience in the coming decade.

INDIA’S INCREASING VULNERABILITY TO TROPICAL CYCLONES
India’s vulnerability to tropical cyclones is the outcome of a complex interaction between geography, demography, and climate dynamics. While technological advancements have reduced mortality, climate change and sea-level rise continue to amplify economic and ecological risks. Sustainable coastal development and community resilience are essential to secure India’s future against intensifying tropical storms.
