Early Civilization

Over 1,100 years before William the Conqueror became the King of England after the Battle of Hastings, Julius Caesar came, saw, and conquered part of “Britannia”, setting up a Roman province with a puppet king in 54 BCE. In the new province, the Romans eventually constructed a military outpost overlooking a bridge across the River Thames. The new outpost was named Londinium, and it covered just over two dozen acres. By the second century CE, Londinium was a large Roman city, with tens of thousands of inhabitants using villas, palaces, a forum, temples, and baths.

Most scientists believe the evolution of humans has a history nearly as long as life itself. Anatomically modern humans and all other life that has existed on the planet first came about from the single-celled microorganisms that emerged approximately four billion years ago. Through the processes of mutation and natural selection, all forms of life developed, and this continuous lineage of life makes it difficult to say precisely when one species completely separates from another.
