The duckling started swimming out of instinct when she followed the rest of the flock into the lake for the first time. Your instinct when you touch something very very hot is to move your hand right away without thinking.
Dinosaurs
The first dinosaurs lived in the beginning of the Mesozoic Era (or the Age of Reptiles). Birds were amazingly discovered to be dinosaurs so dinosaurs were also alive in the Cenozoic (that's our time-the Age of Mammals) to today.
About 230 million years ago.
No. Sharks appeared on earth long before the first dinosaurs did.
The first dinosaurs evolved in the Mesozoic. At the end of the Mesozoic, all non avian dinosaurs became extinct. Therefor, all non avian dinosaurs, and some avian dinosaurs (birds), lived in the Mesozoic.
1957 when the dinosaurs became extinct
The first dinosaurs evolved in the Mesozoic. At the end of the Mesozoic, all non avian dinosaurs became extinct. Therefor, all non avian dinosaurs, and some avian dinosaurs (birds), lived in the Mesozoic.
The earliest reptiles known evolved around 312 million years ago, and looked a lot like lizards. However, they were not actually lizards. The oldest known lizard fossil dates to 220 million years ago, about the same time that dinosaurs evolved. That was during the Triassic period of the Mesozoic era.
The first birds appeared during the Jurassic period, around 150 million years ago. They are believed to have evolved from small theropod dinosaurs.
They appear in the fossil record in the late Triassic about 230 million years ago and go extinct around 65 mya.
