Answer:
extant; extinct.
Explanation:
A species is a group of individuals that can interbreed to produce fertile and viable progeny. A species may be present on the earth and is surviving or may not be present now on the earth and have become extinct due to one or more reasons. Extant species are the species living on the earth in the present time while extinct species do not exist now. For instance, <em>Plateosaurus engelhardti</em> is a species of dinosaurs that survived on the earth during the Triassic period but does not exist now. On the other hand, <em>Homo sapiens, Apis indica</em> are some of the examples of the extant species that are surviving on the earth.

Chameleons, those shade-shifting, intricately camouflaged lizards that can change color in response to environmental or behavioral influences. Since the oldest lineages of chameleons are all from Madagascar, scientists believe they evolved on the island and spread out from there. As far as paleontologists can tell, the first chameleons evolved shortly after the extinction of dinosaurs 65 million years ago. Unlike other animals that change color, such as the squid and octopus, chameleons do not modify their hues by accumulating or dispersing pigments within their skin cells, the researchers found. Instead, the lizards rely on structural changes that affect how light reflects off their skin, the researchers said. Although chameleons are believed to have originated in Africa or Madagascar, the oldest known fossil, 26 million years old, is Chamaeleo caroliquarti from western Bohemia.
