Question

During which geological period of evolution did the greatest diversification of life occurred on the earth?
A) Permian
B) Jurassic
C) Cambrian
D) Ordovician

Answer 1

Hint:Evolution is a change in biological populations' heritable traits over subsequent generations. These traits are the manifestations of genes that are passed down during reproduction from parent to offspring.

Complete answer:
The Cambrian period, which occurred between around 542-488 million years ago. It marks the quickest evolution in the history of the World of new animal diversity. It is thought that during this period, much of the animal phyla that remains today had its beginnings, sometimes referred to as the Cambrian eruption. During this time, echinoderms, molluscs, worms, arthropods, and chordates appeared. During the Cambrian period, one of the most influential species was the trilobite, an arthropod that was among the first animals to show a sense of vision. The wide expansion of animal types, which seems to have started during the Cambrian era, persisted well into the Ordovician period that followed the Cambrian period.

The Permian is a geological period and system that ranges from the end of the Carboniferous period 298.9 million years ago to the beginning of the Triassic period 47 million years ago.

A mild, wet climate, which gave rise to lush vegetation and abundant life, characterised the Jurassic period. The Earth's climate has shifted from hot and dry to humid and subtropical during this time.
The Ordovician Period starting 488.3 million years ago and ending 443.7 million years ago, lasted almost 45 million years. The region north of the tropics was almost completely ocean during this time, and much of the world's land was collected in Gondwana

Hence, the correct answer is option ‘C’, Cambrian.

Note:During the Jurrasic period, many new dinosaurs, in large numbers, have appeared. Stegosaurus, brachiosaurus, allosaurus, and many others were among them. Almost 65 million years went by until humans emerged on Earth after the dinosaurs died out. Around the time of the dinosaurs, though, small mammals were alive.
