North Island Takahē
The North Island takahē ( mi, moho) (''Porphyrio mantelli'') is an extinct rail that was found in the North Island of New Zealand. This flightless species is known from subfossils from a number of archeological sites and from one possible 1894 record (Phillipps, 1959). It appeared to have been even larger than the South Island takahē and, if it did survive until the 1890s, would have been the largest rail in historic times. The decline of the species has generally been attributed to the increasing incursion of forest into the alpine grasslands through the Holocene, although hunting by the Māori also played a major role. Traditionally the North Island takahē was considered conspecific with the endangered South Island takahē ''P. hochstetteri''. Trewick (1996) presented evidence that the two taxa were independently derived from flying ancestors, so proved to be separate species. The binomial of this bird commemorates the naturalist and civil servant Walter Mantell Walte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Richard Owen
Sir Richard Owen (20 July 1804 – 18 December 1892) was an English biologist, comparative anatomist and paleontologist. Owen is generally considered to have been an outstanding naturalist with a remarkable gift for interpreting fossils. Owen produced a vast array of scientific work, but is probably best remembered today for coining the word '' Dinosauria'' (meaning "Terrible Reptile" or "Fearfully Great Reptile"). An outspoken critic of Charles Darwin's theory of evolution by natural selection, Owen agreed with Darwin that evolution occurred, but thought it was more complex than outlined in Darwin's ''On the Origin of Species''. Owen's approach to evolution can be considered to have anticipated the issues that have gained greater attention with the recent emergence of evolutionary developmental biology. Owen was the first president of the Microscopical Society of London in 1839 and edited many issues of its journal – then known as '' The Microscopic Journal''. Owen als ...
