మొసలి
మొసలి భూమిమీద చాలా పురాయుగంనుండి, అనగా డైనోసార్‌ల కాలం నుండి ఉన్నాయి. మొసళ్ళు భూమిమీద 200 మిలియన్ సంవత్సరాల క్రితంనుండి ఉన్నాయని అంచనా. డైనోసార్‌లు 65 మిలియన్ సంవత్సరాల క్రితం అంతరించాయి. అప్పటినుండి కూడా మొసళ్ళ శరీరనిర్మాణంలో పెద్దగా మార్పులు ఏవీ వచ్చినట్లు లేదు. భూమి మీద మరెన్నో జాతులు అంతరించినప్పటికీ మొసళ్ళ జాతి నిలబడింది.[1]

Anthony Cheke pointed out that some descriptions after 1662 use the names "Dodo" and "Dodaers" when referring to the red rail, indicating that they had been transferred to it after the disappearance of the dodo itself. Cheke therefore points to the 1662 description as the last credible observation. A 1668 account by English traveller John Marshall, who used the names "Dodo" and "Red Hen" interchangeably for the red rail, mentioned that the meat was "hard", which echoes the description of the meat in the 1681 account. Even the 1662 account has been questioned by Errol Fuller, as the reaction to distress cries matches what was described for the red rail. Until this explanation was proposed, a description of "dodos" from 1681 was thought to be the last account, and that date still has proponents. Recently accessible Dutch manuscripts indicate that no dodos were seen by settlers in 1664–1674. It is unlikely the issue will ever be resolved, unless late reports mentioning the name alongside a physical description are rediscovered. The IUCN Red List accepts Cheke's rationale for choosing the 1662 date, taking all subsequent reports to refer to red rails. In any case, the dodo was probably extinct by 1700, about a century after its discovery in 1598. The Dutch left Mauritius in 1710, but by then the dodo and most of the large terrestrial vertebrates there had become extinct.
