Question: Passage: The spotted green pigeon or Liverpool pigeon (Caloenas maculata) is a species of pigeon which is most likely extinct. It was first mentioned and described in 1783 by John Latham, who had seen two specimens of unknown provenance and a drawing depicting the bird. The taxonomic relationships of the bird were long obscure, and early writers suggested many different possibilities, though the idea that it was related to the Nicobar pigeon (C. nicobarica) prevailed, and it was therefore placed in the same genus, Caloenas. Today, the species is only known from a specimen kept in World Museum, Liverpool. Overlooked for much of the 20th century, it was recognised as a valid extinct species by the IUCN Red List only in 2008. In 2014 a genetic study confirmed it as a distinct species related to the Nicobar pigeon, and showed that the two were the closest relatives of the extinct dodo and Rodrigues solitaire.
 Link Information: The animal order Columbiformes is also constituted of pigeons and doves, and includes about 42 genera and 310 species.
 Question: How many species of pigeons are there?

Answer: Answer: 310


Question: Passage: Lyell's wife died in 1873, and two years later (in 1875) Lyell himself died as he was revising the twelfth edition of Principles. He is buried in Westminster Abbey. Lyell was knighted (Kt) in 1848, and later, in 1864, made a baronet (Bt), which is an hereditary honour. He was awarded the Copley Medal of the Royal Society in 1858 and the Wollaston Medal of the Geological Society in 1866. Mount Lyell, the highest peak in Yosemite National Park, is named after him; the crater Lyell on the Moon and a crater on Mars were named in his honour; Mount Lyell in western Tasmania, Australia, located in a profitable mining area, bears Lyell's name; and the Lyell Range in north-west Western Australia is named after him as well. In Southwest Nelson in the South Island of New Zealand, the Lyell Range, Lyell River and the gold mining town of Lyell (now only a camping site) were all named after Lyell. The jawless fish Cephalaspis lyelli, from the Old Red Sandstone of southern Scotland, was named by Louis Agassiz in honour of Lyell.
