in the course of fish evolution, two of the gill slits slowly advanced into the jaws.
The evolution of fish started about 530 million years in the past at some point during the Cambrian explosion. It become during this time that the early chordates advanced the cranium and the vertebral column, main to the first craniates and vertebrates. the first fish lineages belong to the Agnatha or jawless fish.
The earliest fish, corresponding to living hagfish, developed about 550 million years in the past. Diversifications that in the end advanced in fish include an entire vertebral column, jaws, and an endoskeleton manufactured from bones in preference to cartilage. Fish live in the course of the sea and in freshwater lakes and streams.
New studies have uncovered the genetic foundation of gill covers in fish, which came about over 430 million years ago. It sheds light on one of the most essential evolutionary traits for fish, in addition to over vertebrates.
In jawless fishes, a sequence of gills opened behind the mouth, and those gills became supported by way of cartilaginous elements. the primary set of these elements surrounded the mouth to shape the jaw.

A primary election is an election during which voters can indicate their preferred candidate in an upcoming general election. In other words its a process for narrowing the number of candidates for general elections.
General Election is a process, during which, nation's primary legislative candidates a nation or state are elected. Generally they are held at some intervals such as every four years.
Special Election is an election scheduled at unusual date for a specific purpose. It happens generally to fill an position that has become vacant before the incumbent has completed the term.
Run-off Election means an initial election did not result in a winner because it was tied or too close to call. A runoff election settles the matter, providing a final decision.
A Recall Election (is also known as recall referendum and it is a procedure when voters elected official can be removed from the post via direct vote before that official's term has ended.
Considering the above statement, the person that is most likely to be the author is Thomas Paine.
Thomas Paine is known as the Author of Common Sense in 1776 towards the American War of Revolution.
He was known for being a political activist who constantly challenged the supremacy of the British over the American colonies.
He claimed many times that America needs to be on its own and free from Great Britain.
Given that this excerpt challenges the advantages gained from Great Britain by North America, this reflects the continental mind of Thomas Paine.
Hence, in this case, it is concluded that the correct answer is Thomas Paine.
