In our online lecture we include a quote by E. O. Wilson, “The one process now going on that will take millions of years to correct is the loss of genetic and species diversity by the destruction of natural habitats. This is the folly our descendants are least likely to forgive us.

Throughout Earth’s history, we have had long periods of innovation and radiation of new species which have been interrupted periodically by five major extinction events that eliminated large percentages of the life on Earth. The last of these appears to have involved a collision with a large asteroid resulting in the loss of the dinosaurs at the end of the Cretaceous. Each of these events has been followed by a new period of radiation of new species and innovation.

As Wilson states, we are now in the midst of a sixth major extinction event that has been brought on by the actions of humans.

Describe the common pattern of alternating extinctions and radiations. Consider Wilson’s statement. What evidence can you find to support or refute that statement? Do you agree with Wilson? Explain why you do or don’t agree and present the evidence supporting your opinion

The major extinction events and biodiversity
Describe the typical pattern of alternating extinctions and radiations. Consider Wilson’s
statement. What evidence can you find to support or refute that statement? Do you
agree with Wilson? Explain why you do or don’t agree and present the evidence
supporting your opinion
The extinction of the plants, animals and some other organisms is caused by human services
and activities.it occurs when there is no longer existence of the species in any part of the
world. The species is assumed to have died out hence being considered as natural part of the
evolution. The extinction is traced as late as Pleistocene for the last 12,000 years. The first
wave of the destruction mainly targets the larger vertebrates that were caught by the hunters
and the gatherers (Gaston, & Spicer, 2013). The second wave began over 10,000 years ago
when discovery in agriculture led to the enormous increase in the human population. This
resulted in the increment in need of covering the environment of wildlife, maintaining larger
herds of the domestic cattle, diverting streams to achieve the goals of the signifi...
