It will take millions of years for mammals to recover from the current extinction crisis. The sixth mass extinction, unlike previous mass extinctions on Earth, is anthropogenic or anthropogenic.
A team of biologists recently published its findings on the impact of humans on biodiversity and the time required for evolution to "restore" extinct lineages. The team discovered that if humans do not double on mammal conservation, if many mammals die out over the next 50 years, it would take between 3 and 5 million years for lost lineages to regain their evolution .
Geologists have documented five massive extinctions over the past 450 million years. The most recent extinction event was the Cretaceous-Tertiary (K-T) extinction about 66 million years ago. This extinction event was responsible for the killing of non-avian dinosaurs.

The extinction of the dinosaurs is the most recent example of the Earth's reaction to a sudden and dramatic reduction in phylogenetic diversity. Over time, these gaps in phylogenetic diversity eventually resolve with new species.
However, the current extinction event is quite different from past extinction events triggered by sudden and singular events. The current extinction event depends on the behavior and decisions of the man, which means that there is no definite end to the event of the day. 39, current extinction.
It is natural and natural for species to disappear, which are then replaced as new species evolve. However, in modern times, evolution can not keep pace with the extinction caused by human actions.
The authors also note that not all mammals are created of equal phylogenetic significance. For example, there were only four species of saber-toothed tigers and they all disappeared, thus cutting off an entire branch of the evolving mammalian tree. The loss of distinct evolutionary lineages removes millions of years of evolutionary history and eliminates the ecological functions of these species on Earth's ecosystems. In comparison, the authors note that there are hundreds of species of shrews, which means that the extinction of many of these species does not eliminate the entire evolutionary branch.
Based on this information, the authors provide context for species that may play a greater role in protection, those with unique evolutionary composition, and that are represented by only a few species.

The authors also note that large mammals were widespread during the ice age. Since then, humans have preferably killed larger mammals, causing the extinction of larger mammals. The authors predict that this trend will continue, with humans eliminating larger mammals. Finally, the evolution tree will be left to small mammals. If the extinction pressure is relaxed, mammals can begin to diversify even further, from the smallest to the largest.
The big question in the study of extinctions is what humans will do in the decades and centuries to come. The sixth mass extinction has no end result and depends heavily on our collective choices.
