A New Species of Fanged Frog with Internal Fertilization and Birth of Tadpoles


Abstract
We describe a new species of fanged frog (Limnonectes larvaepartus) that is unique among anurans in having both internal fertilization and birth of tadpoles. The new species is endemic to Sulawesi Island, Indonesia. This is the fourth valid species of Limnonectes described from Sulawesi despite that the radiation includes at least 15 species and possibly many more. Fewer than a dozen of the 6455 species of frogs in the world are known to have internal fertilization, and of these, all but the new species either deposit fertilized eggs or give birth to froglets.

For the first time, frogs have been seen giving birth to tadpoles.

Most frogs lay eggs and although some species give birth to froglets, newborn tadpoles are new to science.

Dr. Jim McGuire from the University of California, Berkeley, actually thought he was holding a male frog the first time he witnessed a birth.

This new frog is one of only 10 or 12 species that has evolved internal fertilization, and of those, it is the only one that gives birth to tadpoles, as opposed to froglets or laying fertilized eggs.”

So maybe it is not necessarily that the others couldn’t do it (apparently this amphibian can). But they don’t do it, for various reasons.

No one currently knows how the tadpoles’ parents manage to do it.

It’s not what we know about the evolution of life on Earth but what we didn’t know that will sink Darwin’s Tree of Life.

Fenomena Big Bang

B ig Bang merupakan petunjuk nyata bahwa alam semesta telah ‘diciptakan dari ketiadaan‘, dengan kata lain ia diciptakan oleh Allah. Karena alasan ini, para astronom yang meyakini paham materialis senantiasa menolak Big Bang dan mempertahankan gagasan alam semesta tak hingga. Alasan penolakan ini terungkap dalam perkataan Arthur Eddington, salah seorang fisikawan materialis terkenal yang mengatakan: “Secara filosofis, gagasan tentang permulaan tiba-tiba dari tatanan Alam yang ada saat ini sungguh menjijikkan bagi saya”. Seorang materialis lain, astronom terkemuka asal Inggris, Sir Fred Hoyle termasuk yang paling merasa terganggu oleh teori Big Bang. Di pertengahan abad ke-20, Hoyle mengemukakan suatu teori yang disebut Steady-state yang mirip dengan teori ‘alam semesta tetap‘ di abad ke-19. Teori Steady-state menyatakan, alam semesta berukuran tak hingga dan kekal sepanjang masa. Dengan tujuan mempertahankan paham materialis, teori ini sama sekali berseberangan dengan teori B...
