Finches on the Galapagos Islands are thought to have originated from South America and to have evolved into new species over the last 10,000 years. Some of this evolution is represented in the diagram shown. The success of the finches on the Galapagos was m ost likely due to the (1) large numbers of other birds competing (3) birds occupying the same island for food (2) mutations occurring in every offspring (4) birds adapting to different niches t aaDeaBs 316 Fl ieuNmb:er geRnest eDta an3J012 37 /313/1202 3BLA wnsrAe 4 adaptation 6.1 The diagram shown represents the bone arrangements in the front limbs of three different species of mammals.

Y es, This Big Lizard is Pink. A new study from the University of Rome Tor Vergata shows that a rare strawberry-tinted land iguana [rosada iguana] in the Galapagos Islands is genetically distinct from other iguanas there, having diverged from them more than five million years ago as the archipelago [a group of islands] formed. The rosada iguana, which escaped Darwin’s notice, was discovered only recently, largely because it lives on the desolate slopes of an active volcano. Source: Smithsonian, March 2009.
