1. extinctions

   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. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included.

Examples of Extinctions in a Sentence

1. Margaret Hunter:

   We’ve seen that these pythons can remove 90 percent or greater of the mammals throughout the Everglades, so, we’re quite concerned about the populations of these animals in South Florida potentially leading to local extinctions of these populations.

2. Mark Krockenberger:

   We run a very high risk, if this vaccine strategy doesn't work... of localized extinctions.

3. John Scanlon:

   In some parts of the African continent we are confronting potential local extinctions, in particular in central and western Africa.

4. Andrew Pask:

   We would strongly advocate that first and foremost we need to protect our biodiversity from further extinctions, but unfortunately we are not seeing a slowing down in species loss, this technology offers a chance to correct this and could be applied in exceptional circumstances where cornerstone species have been lost.

5. Ross MacPhee:

   Despite their ungainly appearance, different species of glyptodonts occupied habitats as distinct as open grassland and dense woodland, all the way from Patagonia to the southern parts of the continental United States, although their disappearance has been blamed on human depredation as well as climate change, some species persisted into the early part of the modern or Holocene epoch, long after the disappearance of mammoths and saber-toothed cats. Like the loss of giant ground sloths, mastodons, and dozens of other remarkable mammalian species, the precise cause of the New World megafaunal extinctions remains uncertain.
