Answer:

may it help u.

Explanation:

In this diagram we see 3 era,at bottom in the palazoic era there are small aquatic animals like starfish,snail you see.In earth the life was exposed in the water at first, after some time we see many fishes has come.

so we can say at first the invertebrates has come like starfish,then vertebrate animals has come into earth like fishes..

in palazoic era's third stage- the fishes has came into lands.. they are adapted by their power and nature, so they could live on land and water, so they are reptiles as frogs..

in mesozoic era some animals lived only on land.. they are adapted and Dinosaurs came... so it is the age of reptile...

when Dinosaur had gone the birds has came... by the process of evolution, their first two hands changed into wings...

in the cenozoic era birds , rabbit,bat many mamals has come ,they don't lay eggs like birds.. at last the man has come...

hope you can understand...
