New laser scans of the dodo, perhaps the most famous animal to have gone extinct in human history, have unexpectedly exposed portions of its anatomy unknown to science, which are revealing secrets about how the bird once lived. Thedodo was a flightless birdabout 3 feet (1 meter) tall that...
Another flightless bird that has become extinct is the moa. The moa lived on the North and South Islands of New Zealand. Like the dodo the moa’s legs were shorter but some of these birds grew to be more than ten feet tall. And the causes of its extinction is the same as the dodo...

题目Imagine an island untouched by humans and without any large mammals.Colorful and strange birds of all shapes and sizes fly over forests and seaside hills.The sky is painted with endless clouds.Flightless birds nest safely on the ground,and seabirds cover the beaches.The sound...
The largest species is the nearly extinct leatherback sea turtle. It may reach even 2 meters (6ft 7in) of length and weigh over 1 ton (2,200 lb). The rapidity of turtle actions depends on the ambient temperature: heat makes them lazy, while they move quite fast in the cold. ...
O Strong evidence for overexploitation comes from the extinction of many species of flightless birds on Pacific islands after these places were colonized by humans. O The fact that only flightless-bird species became extinct on Pacific islands after the arrival of humans could indicate that overexploi...
