It is said that biological evolution started around 3.7 billion years ago. Fact – No- 3 Homo sapiens or modern man emerged 250000 years ago. The evolution of humans has taken around 5 million years. Fact – No- 4 Dinosaurs were not the first reptile to evolve. Dinosaurs came to earth 220 million years ago, whereas the first reptile crawled on land 340 million years ago. Fact – No- 5 Seals, dogs, and bears are closely related to carnivores. But they are on a different branch of the evolutionary tree than hyenas and cats.

Dolphins are evolved from the mammals, whereas sharks are evolved from the fishes.   Also Read:  Aquatic Ecosystem Fact – No- 13 A minor change occurred inside one species can add up and generate a whole new species. Fact – No- 14 Fossils are the remains of the non-degraded parts of  living things  found within rocks. They are the only evidence for their existence of extinct species. Fact – No- 15 All humans from our ancestors are a single species. According to the fossils discovered, human species arose about 300,000 years ago. Fact – No- 16 The first basic theory of evolution was developed in the 13th century by medieval Persian scholar Nasir al-Din al-Tusi. This was developed 600 years before Darwin’s discoveries- Origin of Species.
