April 23: World Book Day

Every year, World Book Day or International Day of Book or World Book and Copyrights Day is organised by United Nations Educational Scientific and Cultural Organization (UNESCO).


The World Book Day is being celebrated since 1995. The idea of World Book Day was given a writer Vicente Clavel Andres to celebrate World Book Day on the death anniversary of author Miguel de Cervantes.

Initially his birthdate October 7 was proposed. But as the death anniversaries of William Shakespeare and Inca Garcilaso de la Vega also falls on April 23, the later was selected.

However, in reality Shakespeare died 10 days after Cervantes. This was because when the legends lived, Spain used Gregorian calendar and England used Julian Calendar.

Miguel de Cervantes

Miguel de Cervantes was a Spanish writer. He was well known for the classic western literature “Don Quixote”. He lived in 17th century. He was a soldier, poet, novelist, tax collector and a playwright. He was forced to leave Spain and hence he worked as a cardinal in Rome.

Fossil links human hands to fins for the first time in Human Evolution

The Paleontologists of Canada have linked human hands to the fins of fish. The researchers examined a fossil of “Elpistostege”.

About the findings

The Elpistostege represents the pivotal stage of transition of fish into land vertebrates. The transition was supported by the front fins of the fish called the pectoral fins. These fins had radial bones that were arranged in a row like that of fingers. These bones should have given the flexibility to bear weight on land.


The Elpistostege was completely aquatic. It had a crocodile-like body, flat triangular head, numerous teeth around jaws. The paleontologists believe that during its era, Elpistostege was the top predator in brackish estuary ecosystem. The Elpistostege lived during Devonian period. The four-limbed animals that evolved from these Elpistostege were called tetrapods.

Devonian Period

The Devonian Period spans for 60 million years and is around 419 million years ago. It is named after the place Devon, England where the rocks of the era were first found.
