Carboniferous :- Amphibians come into existence originate during Devonian period (i.e. 400 million years ago) and dominated during carboniferous period (i.e. 350 million years ago) of paleozoic era. The Carboniferous period in also called the age of amphibians.

The golden age of reptiles is
1 Coenozoic era
2 Palaeozoic era
3 Mesozoic era
4 Silurian period
Explanation:
Mesozoic era :- The Mesozoic era (about 66 million years ago) is known for golden age of reptiles and gymnosperms. This era is also called as Age of medieval life. Specially in Jurassic period Dinosaurs are dominant, therefore this period is called as the age of reptiles which existed about 145 million year ago in Mesozoic era.

According to Lamarckism, long necked Giraffes evolved because:
1 Humans preferred only long necked ones
2 Of stretching of necks over many generations by short necked ones
3 Nature selected only long necked ones
4 Short necks suddenly changed into long necks
Explanation:
According to Lamarckism, long necked Giraffes evolved because of stretching of necks over many generation by short necked ones. Lamarck argued that giraffes evolved long because Their ancestors stretched their necks to reach leaves high in trees because the ground vegetation is less developed. This stretching caused physical changes in the necks, which were then passed on the next generation.

Mammals are believed to have evolved from reptiles in:
1 Triassic
2 Jurassic
3 Permian
4 Cretaceous
Explanation:
Origin of mammals took place in Triassic period. It means dinosaurs and mammals originated in the same period. Long before the arrival of true mammals, one group of extinct reptiles, the Synapsida acquired several mammalian characteristics. They lived throughout the Permian and Triassic periods. The more mammals like Synapsids belonged to the order Therapsida.

Which one of the following periods is largely associated with extinction of dinosaurs and increase in the flowering plants and reptiles?
1 Jurassic
2 Triassic
3 Cretaceous
4 Permian
Explanation:
Cretaceous period (135 million years ago) of Mesozoic era is associated with extinction of dinosaurs and toothed birds rise of modern fishes and birds and of placental mammals. This period has also dominance of flowering plants.
