Estimates of current rates of extinction suggest that rates of extinction have globally decreased, but have locally increased suggest that one-half of all animal and plant species may be gone by the year 2100 indicate that rates may be greater than extinction rates seen in the fossil records indicate that rates of speciation equal extinction, so an equilibrium has been reached.

Respuesta :

The estimates of the current rates of extinction indicated that rates may be greater than the mass extinctions at the close of the Cretaceous period.

What is the Cretaceous Period?

The Cretaceous Period was an historical period noted for being the last portion of the "Age of Dinosaurs"

Hence, the estimates of the current rates of extinction indicated that rates may be greater than the mass extinctions at the close of the Cretaceous period.

Therefore, the Option C is correct.
