Restoring recently-extinct species will take 8 million years: study

  • It will take at least eight million years to restore species recently lost to extinction, according to a new study.
  • In Caribbean alone, more than half of the mammal species went extinct after human colonisation.
  • New World leaf-nosed bats form an ecologically diverse group that includes the fishing bat, many fig-eating bats and vampire bats. The group is ideal for studying the effects of recent extinction, as one-third of its species have become extinct in the Greater Antilles over the past 20,000 years.
  • While there is a debate as to what caused these extinctions, the largest wave of species loss came after human arrival.
  • Human-caused changes to Earth’s ecosystems are accelerating and this study offers important information on how those changes will affect the loss and recovery of species in the future.
