How was the first fish born?

The evolution of fish began about 530 million years ago during the Cambrian explosion. It was during this time that the early chordates developed the skull and the vertebral column, leading to the first craniates and vertebrates. The first fish lineages belong to the Agnatha, or jawless fish.

What animal is older than dinosaurs?

Prehistoric turtles coexisted with dinosaurs until they went extinct 65 million years ago. These turtles belonged to a group of ancient reptiles called Archelon, which is closely called related to the leatherback sea turtle we can see these days.

How long have humans existed?

We are still learning about our ancestors, but we guess that the first humans existed between five and seven million years ago: the median time is six million years ago. These humans walked upright on two legs, just like us. Around 90,000 years ago, these humans started making tools to catch fish.
