The Verge of Extinction

Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point.

Nearly all of the world’s emperor penguin colonies may be pushed to the brink of extinction by 2100, a study has found, as the United States moves to list them as threatened under the Endangered Species Act.

Extinction is the dying out Eof a species. Extinction plays an important role in the evolution of life because it opens up opportunities for new species to emerge. When a species disappears, biologists say that the species has become extinct. A new study has shown that since 1750, more than double the number of plants have disappeared from the wild than birds, mammals and amphibians combined.
