Meski ukurannya hanya beberapa sentimeter,<\/p>\n<p>konodont menyimpan struktur gigi yang belum pernah tertandingi oleh spesies mana pun, baik yang sudah punah maupun yang masih hidup.<\/p>\n<p>Penelitian yang dipublikasikan dalam jurnal ilmiah Proceedings of the Royal Society B ini dilakukan oleh tim ilmuwan dari University of Bristol, Inggris, dan Monash University, Australia.<\/p>\n<p>Mereka memanfaatkan teknologi sinar-X beresolusi tinggi dari akselerator partikel di Jepang untuk memindai fosil tanpa merusaknya.<\/p>\n<p>Fokus penelitian tertuju pada spesies Wurmiella excavata. Dari hasil pemindaian tiga dimensi, ilmuwan menemukan bahwa ujung gigi konodont hanya berukuran sekitar dua mikrometer\u00a0 sekitar seperlima puluh dari ketebalan rambut manusia.<\/p>\n<p>Temuan ini menjadikannya sebagai struktur gigi paling tajam yang pernah diketahui. Tak hanya itu, cara makan konodont juga berbeda dari kebanyakan vertebrata.<\/p>\n<p>Jika hewan modern mengunyah dengan gerakan atas-bawah, konodont menggunakan mekanisme mengiris dari sisi ke sisi, seperti gunting.<\/p>\n<p>Kombinasi antara ketajaman ekstrem dan teknik ini memungkinkan mereka memotong mangsa dengan efisien meski tanpa kekuatan rahang besar.<\/p>\n<p>Yang lebih mencengangkan, para peneliti menemukan indikasi bahwa konodont mampu \u201cmengasah\u201d kembali giginya saat aus. Hingga kini, belum ada hewan lain yang diketahui memiliki kemampuan serupa dalam evolusi.<\/p>\n<p>Secara komposisi, gigi konodont tersusun dari apatit\u2014mineral yang juga ditemukan pada enamel gigi manusia. Namun berbeda dengan manusia yang mengutamakan ketahanan, konodont berevolusi untuk mencapai ketajaman maksimal, bahkan dengan mengorbankan daya tahan.<\/p>\n<p>Penemuan ini menjadi pengingat bahwa dalam evolusi, ukuran bukanlah segalanya. Justru, makhluk kecil dengan adaptasi ekstrem bisa menjadi yang paling efisien dan mematikan di zamannya.***<\/p>\n<p>Sumber :<\/p>\n<p>Penelitian dalam jurnal Proceedings of the Royal Society B<\/p>\n<p>University of Bristol<\/p>\n<p>Monash University<\/p>\n<p>Riset paleontologi tentang Conodont dan Wurmiella excavata<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Beritamerdeka.co.id &#8211; Selama berabad-abad, para ilmuwan dan masyarakat&#8230;<\/p>\n","protected":false},"author":13,"featured_media":19602,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_jetpack_memberships_contains_paid_content":false,"footnotes":""},"categories":[2],"tags":[2751,3509,3510],"newstopic":[],"class_list":["post-19612","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-internasional","tag-gigi","tag-makhluk","tag-purba"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.5 -
