Detailed explanation-3: -Australia’s extinction rate for mammals is the highest in the world. Scientists estimate that at least 34 mammals have gone extinct since the British colonization of the continent beginning in the late 18th century.
Detailed explanation-4: -The rate of speciation at the equator was found to be around 0.18 new species per species per million years. The extinction rate here was around 0.04. At the transition between tropical and temperate (23 latitude) regions, the speciation rate was higher at around 0.38 and extinction rate at 0.25.
