Such physical struggle is indeed necessary to evolve and maintain a type fit for the struggle.
On September 8, 1900, a Category 4 hurricane ripped through Galveston, Texas, killing an estimated 6,000 to 8,000 people. At the time of the 1900 hurricane, Galveston, nicknamed the Oleander City, was filled with vacationers.
Storm tides of 8 to 15 feet (2.4 to 4.6 meters) inundated the whole of Galveston Island, as well as other portions of the nearby Texas coast, according to a National Hurricane Center (NHC) historical account. These tides were largely responsible for the 8,000 deaths (estimates range from 6,000 to 12,000) attributed to the storm.
