Extinctions caused directly or indirectly by humans are occurring at a rate that far exceeds any reasonable estimates of At our current rate of extinction, we’ve seen significant losses over the past century. A recent study looked closely at observed vertebrate extinction data over the past 114 years. They then considered how long it would have taken for that many species to go extinct at the background rate. 2020-03-24 2018-05-21 2021-04-11 This implies that average extinction rates are less than average diversification rates. Median diversification rates were 0.05–0.2 new species per million species per year.
