This view was met with ridicule, but was later supported by English naturalists Hugh Edwin Strickland and Alexander Gordon Melville in their 1848 monograph The Dodo and Its Kindred, which attempted to separate myth from reality. After dissecting the preserved head and foot of the specimen at the Oxford University Museum and comparing it with the few remains then available of the extinct Rodrigues solitaire (Pezophaps solitaria), they concluded that the two were closely related.

Imam as-Sadiq (PBUH) said: Try to obtain knowledge and ornament it with patience and dignity; and be humble for the one who learns knowledge from you.

Imam al-Sadiq (PBUH) said: Be careful of your knowledge and see from whom you get it.

The dodo was variously declared a small ostrich, a rail, an albatross, or a vulture, by early scientists.[3] In 1842, Danish zoologist Johannes Theodor Reinhardt proposed that dodos were ground pigeons, based on studies of a dodo skull he had discovered in the collection of the Natural History Museum of Denmark.

Imam Ali (PBUH) said: The one who seeks for knowledge is like a warrior in the cause of religion for the way of Allah.

Imam al-Baqir (PBUH) said: Try to learn knowledge because learning it is a good action and study is itself a worship.

The extinction of the dodo less than a century after its discovery called attention to the previously unrecognized problem of human involvement in the disappearance of entire species. The dodo achieved widespread recognition from its role in the story of Alice Adventures in Wonderland, and it has since become a fixture in popular culture, often as a symbol of extinction and obsolescence.

The last widely accepted sighting of a dodo was in 1662. Its extinction was not immediately noticed, and some considered the bird to be a myth. In the 19th century, research was conducted on a small quantity of remains of four specimens that had been brought to Europe in the early 17th century. Among these is a dried head, the only soft tissue of the dodo that remains today. Since then, a large amount of subfossil material has been collected on Mauritius, mostly from the Mare aux Songes swamp.

It is presumed that the dodo became flightless because of the ready availability of abundant food sources and a relative absence of predators on Mauritius. Though the dodo has historically been portrayed as being fat and clumsy, it is now thought to have been well-adapted for its ecosystem.

The first recorded mention of the dodo was by Dutch sailors in 1598. In the following years, the bird was hunted by sailors and invasive species, while its habitat was being destroyed.

The Holy Prophet (peace be upon him and his progeny) said: Knowledge is Allahs deposit on the earth and scholars are His trustees of it. Therefore, he who acts according to his knowledge, has really delivered His deposit

the dodos has been depicted with brownish-grey plumage, yellow feet, a tuft of tail feathers, a grey, naked head, and a black, yellow, and green beak. It used gizzard stones to help digest its food, which is thought to have included fruits, and its main habitat is believed to have been the woods in the drier coastal areas of Mauritius. One account states its clutch consisted of a single egg.

Subfossil remains show the dodo measured about 62.6–75 centimeters (2.05–2.46 ft) in height and may have weighed 10.6–17.5 kg (23–39 lb) in the wild. The dodo appearance in life is evidenced only by drawings, paintings, and written accounts from the 17th century. Since these portraits vary considerably, and since only some of the illustrations are known to have been drawn from live specimens, the dodos exact appearance in life remains unresolved, and little is known about its behavior.
