Question

Two similarities between mesozic and Cenozoic era on the basis of evolution​

Answer 1

The Mesozoic and Cenozoic eras are both characterized by the evolution and radiation of dominant species to fill ecological niches and by massive extinction events that shaped the course of evolution.

Step-by-step explanation:

Two similarities between the Mesozoic and Cenozoic eras on the basis of evolution are:

• The evolution and radiation of dominant species to fill ecological niches. In the Mesozoic, it was the age of dinosaurs evolving from reptiles, while in the Cenozoic, it became the age of mammals after dinosaurs were wiped out.
• The occurrence of massive extinction events that shaped the course of evolution. At the end of the Mesozoic, the Cretaceous period was marked by an asteroid impact leading to mass extinction. Similarly, the Cenozoic witnessed the ice ages of the Quaternary Period, which led to significant extinctions and paved the way for new species to emerge.

These eras showcase the dynamic nature of life on Earth and how evolution operates to fill ecological vacancies after mass extinctions.

Answer 2

Similarities between mesozoic era and cenozoic era are defined below :

- Mesozoic era and Cenozoic era both started to evolve right after the mass extinct according to the sources of evolution.

- Mass extinction is stated as (K-extinction) and many of the major life forms evolved during these two eras.

- Fossils of birds and reptiles were found in Mesozoic era and Fossils of mammals were found in the Cenozoic era.
