Why All Life Shares the Same DNA Code?

#Evolution #Raja Abu Bakar #Science ki Duniya Can the eye really evolve on its own — or is it too complex? In this lecture, we walk through every stage of eye evolution, from the first light-sensitive proteins (opsins) 3 billion years ago to the full camera-like eye — and show how every intermediate stage still exists in living animals today. Then we go deeper: DNA, RNA, hormones, embryology, and biochemistry all point to one shared origin of life. ⏱ Chapters: 0:00 — Eye evolution: can it happen? 0:13 — Opsins: 3-billion-year-old light proteins 1:35 — Stage 1: photosensitive skin patch 2:20 — Stage 2: groove (directional vision) 3:00 — Stage 3: fluid-filled cavity 4:10 — Stage 4: transparent tissue 4:55 — Stage 5: full cornea + lens 5:36 — All stages exist in animals alive today 6:50 — Molecular evidence for evolution 26:15 — Hox genes in all animals 36:20 — Why elephants rarely get cancer (TP53) 42:43 — Dopamine, serotonin across all species 1:10:40 — Embryology evidence 1:33:30 — Q&A: Will humans keep evolving? 1:53:00 — Q&A: Evolution and the Quran 🔬 Part of an ongoing evolution lecture series in Urdu/Hindi
