Ayam atau Telur Dulu? Sains Akhirnya Menjawab!
Ayam atau telur, mana yang lebih dulu? Pertanyaan klasik ini sudah dibahas sejak zaman Aristoteles. Video ini menjawabnya dengan sains: dari telur hewan laut purba, telur bercangkang di daratan, dinosaurus theropoda berbulu, sampai domestikasi ayam hutan merah.
Kita juga membahas bagaimana evolusi terjadi bertahap lewat perubahan genetik, rekombinasi, dan seleksi selama banyak generasi, dan kenapa jawabannya bergantung pada definisi "telur ayam".
