D. Silurian 🡪 Devonian 🡪Cambrian🡪 Ordovician Permian 🡪 Carboniferous

Answer 1

The evolutionary history explaining the evolution of different living forms are quite vast. The developmental history of different organisms from the simplest to the most complex one, shows the successive changes which occurred through several generations in the biological population.

Complete answer:
The history of developments of living organisms are represented in three important eras which are the Palaeozoic era, Mesozoic era and Coenozoic era.
The Palaeozoic era is the earliest of the different ears and it lasted for about 541 to 252 million years ago. It is also referred to as early life. It extended up to the Permian Triassic. This era is important as it marked many important events such as the development of most invertebrates groups as well as the evolution of fishes. The rise of amphibians and reptiles as organisms that invaded the land took place in this era. This era also showed the rise and division of different plant groups.
In the order of succession, the Palaeozoic era can be divided into six eras which are Cambrian, Ordovician, Silurian, Devonian, Carboniferous, Permian eras.
The Cambrian era lasted for 541 million years ago to 485.4 million years ago and is the first geological period of the Palaeozoic era. This period marks the development and establishment of the invertebrates and early vertebrates.
The Ordovician followed the Cambrian period and it was represented by the appearance of first vertebrates and rise of the fungi. It also showed the major extinction of many marine species. It was followed by the Silurian period which was represented by the rise of the jawed fishes and insects.
The Devonian era showed the origin and rise of amphibians and diversification of fishes. It was followed by the Carboniferous era. The Carboniferous period showed the rise of reptiles and development of seed-bearing plants. It was followed by the Permian era which showed the rise of early reptiles.
Therefore, the correct option is option B.

Note: The important changes brought about the development of different species of animals and plants as well as several other species were removed and became extinct. The different types of species accumulated the changes and it gave rise to the present-day species of organisms through evolutionary processes that occurred through different eras. The Palaeozoic era is the earliest of all the eras and it was divided into Cambrian, Ordovician, Silurian, Devonian, Carboniferous, Permian periods.
