Question

who roamed the earth before the arrival of human beings ??​

Answer 1

Answer:

Dinosaurs, reptiles, ichthyosaurs, pterosaurs, and plesiosaurs

Explanation:

Before the arrival of human, the Earth abundantly filled with an inhabitant of dinosaurs, ichthyosaurs , pterosaurs etc.  Reptiles, ammonites, and large species of plants and animals all existed along with flying birds and small mammals (land-dwelling).  The mammals survived because of no larger predators to stop them. By the time our planet was four billion years old, the rise of large plants and animals was just beginning. Complexity exploded around that time, as the combination of multicellularity, sexual reproduction, and other genetic advances brought about the Cambrian explosion. Many evolutionary changes occurred over the next 500 million years, with extinction events and selection pressures paving the way for new forms of life to arise and develop.
