The sea crossing by humans to the Sahul landmass (modern Australia and New Guinea) from the Sundaland peninsula occurred around 53,000 to 65,000 years ago. Even with the lower sea level of that time, this crossing would have involved travelling out of sight of land – the overall distances involved at the possible crossing points are all over ...
Early human habitations were often built next to water sources. Rivers would often serve as a crude form of natural sewage disposal. Over the millennia, technology has dramatically increased the distances across which water can be relocated. Furthermore, treatment processes to purify drinking water and to treat wastewater have been improved.
Archaeologists have traced the earliest case of lead pollution by humans to the Aegean Sea region around 5,200 years ago. The findings, published in the journal Communications Earth & Environment ...
4500 BC Around this time, humans began diving into the sea as a source of food gathering, commerce, and possibly even warfare. 4000 BC Egyptians developed sailing vessels, which were probably used only in the eastern Mediterranean near the mouth of the Nile River. 4000 BC - 1000 AD Polynesian colonization of South Pacific Islands.
Hippocrates believed that water had to be clean and pure. Rainwater was the best water, but had to be boiled and strained before drinking to get rid of the "bad smell" and to avoid hoarseness of the voice. [3] [4] He designed a crude water filter to “purify” the water he used for his patients. Later known as the “Hippocratic sleeve ...
However, revisionist scholars are creating new turns in the study of maritime history. This includes a post-1980s turn towards the study of human users of ships (which involves sociology, cultural geography, gender studies and narrative studies); [7] and post-2000 turn towards seeing sea travel as part of the wider history of transport and ...
NEW YORK (AP) — Researchers have uncovered a simple structure from the Stone Age that may be the oldest evidence yet of early humans building with wood. The construction is basic: a pair of ...
As early as 1530, precursors to modern techniques were being explored. [36] However, the most accurate clocks available to these early navigators were water clocks and sand clocks, such as hourglass. [36] Hourglasses were still in use by the Royal Navy of Britain until 1839 for the timing of watches. [36]
