Saintis ingin kembalikan binatang yang telah pupus

Pada Jumaat lalu sekumpulan saintis telah berkumpul di Washington DC untuk berbincang binatang mana yang patut mereka kembalikan semula daripada kepupusan. Disamping itu, mereka juga berbincang dari segi etika, cara dan kenapa untuk melakukannya.

Berikut adalah 10 binatang yang kumpulan saintis tersebut berharap dapat kembali semula di muka bumi ini.

1. Aurochs
    Aurochs dikatakan sebuah mitos. Bagaimanapun saintis percaya ia bukanlah mitos sepenuhnya. Aurochs    hampir menyerupai lembu di zaman sekarang. Ia dikatakan pernah hidup di Eropah, Asia dan Afrika Utara. Aurochs dikatakan telah pupus pada tahun 1627.

2. Dodo
    Dodo dikenali sebagai binatang yang bodoh. Walaubagaimanapun ia dikatakan binatang yang hebat dan berani kerana mampu berkembang tanpa memilih pemangsa semula jadi. Dodo banyak ditemui di Kepulauan Mauritus. Ia dikatakan telah pupus disebabkan oleh manusia yang telah membunuh untuk dijadikan makanan.

3. Itik Labrador
    Itik jenis ini sangat jarang dan sukar untuk ditemui. Ia dikatakan telah pupus sekita 1850 dan 1870. Walau dikatakn rasanya tidak sedap, ianya tetap diburu oleh manusia untuk dijadikan makanan. Jadi kepupusan sebenar tidak dapat dijelaskan dengan tepat.

5. Wooly Mammoth
    Haiwan yang menyerupai sang gajah ini dikatakan haiwan prasejarah yang mana kawsan terakhir ditemui bangkainya adalah di Pulau Wrangel di Lautan Artik 4000 tahun dahulu. Penemuan bangkainya telah membantu saintis mengkaji DNAnya dan haiwan-haiwan lain yang hidup sezaman dengannya.
