Langkah Kecil Ikan Lungfish Protopterus annectens

Jurnal KeSimpulan.com - Video - Ikan Lungfish (Protopterus annectens) menggunakan sirip untuk berjalan. Satu langkah evolusi fauna akuatik berjalan ke darat.

Langkah-langkah korelasional jauh mengambil tempat ketika pertama kali pindah dari air ke darat.

Ikan Lungfish Afrika (Protopterus annectens) memiliki lobus berbentuk sirip terlihat serupa pada leluhur vertebrata awal yang berjalan di darat.

Bukti anekdotal menunjukkan ikan menggunakan ini untuk berjalan di sepanjang tempat buaian danau.

Heather King dari University of Chicago di Illinois, dan rekan merekam Lungfish dalam gerak dan memang berjalan menggunakan dua sirip pelvis.

King melapor ke Proceedings of the National Academy of Sciences.
Behavioral evidence for the evolution of walking and bounding before terrestriality in sarcopterygian fishes
