Choose the wrong statement/s from below :
- During the long period (> 3 billion years) since the origin and diversification of life on earth there were five episodes of mass extinction of species.
- ‘Sixth Extinction’ presently in progress different from the previous in the rates; the current species extinction rates are estimated to be 10 times faster than in the pre-human times.
Answer & explanation
Correct answer: option 1
Large-scale loss of species like the one we are currently witnessing have also happened earlier, even before humans appeared on the scene. During the long period (> 3 billion years) since the origin and diversification of life on earth there were five episodes of mass extinction of species.
‘Sixth Extinction’ presently in progress . The current species extinction rates are estimated to be 100 to 1,000 times faster than in the pre-human times and our activities are responsible for the faster rates. Ecologists warn that if the present trends continue, nearly half of all the species on earth might be wiped out within the next 100 years.
