The process by which modern organisms have descended from their ancestors, with changes in their allele frequencies, is called evolution.
What is Evolution?
Evolution is an interesting process which helps explain and makes us understand the living world around us. Evolution mainly describes the change in characteristics of a species over a huge period of time.

Amazing Facts about Evolution
Fact – No- 1
Researchers are not sure if humans have reached the evolution peak or are still evolving.
Fact – No- 2
Every living entity has evolved from a bacterium which lived billions of years ago. 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

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.
Fact – No- 6
Around 550 million years ago, homo sapiens had a common ancestor with a rod-like sea animal called the lancelet.

The human brain is getting smaller due to evolution. According to scientists, our brain started getting smaller around 20000 years ago.
Fact – No- 8
The wings of penguins evolved into flippers. As swimming was easy for transportation the little wings of penguins evolved into flippers.
Fact – No- 9
Human beings share about 31% of their genes with a single living cell yeast that replicates itself every 90 minutes.
Fact – No- 10
Some dolphins and whales have small bones inside them, which shows that these species once had legs and their ancestors could walk on land. This bone appears as a rear tiny flipper.
Fact – No- 11
Experts believe that goosebumps are remains of the thick hair that covered primitive humans.
Fact – No- 12
No two animals are the same, even if they belong to the same species. For example, Both sharks and dolphins are aquatic organisms with similar body features and they vary in their evolution. Dolphins evolved from mammals, whereas sharks evolved from fishes.

A minor change that 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 the existence of extinct species.
Fact – No- 15
All humans from our ancestors are a single species. According to the fossils discovered, the 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 discovery – Origin of Species.

Fact – No- 19

Fact – No- 20
