肾小球性血尿治疗:钓鱼的英文文章

Fishing is the activity of hunting for fish. By extension, the term fishing is also applied to hunting for other aquatic animals such as various types of shellfish as well as squid, octopus, turtles, frogs and some edible marine invertebrates. The term fishing is usually not applied to the hunting of aquatic mammals such as whales. Fishing is an ancient and worldwide practice with many techniques and traditions, and it has been transformed by modern technological developments.

Fishing is a very ancient practice that dates back at least to the Mesolithic period which began about 10,000 years ago. We know from archaeological features such as shell middens[1], discarded fish bones and cave paintings that sea foods were important and consumed in significant quantities. During this time, most people lived a hunter-gather lifestyle and were, of necessity, constantly on the move. However, where there are a few early examples of permanent settlements (though not necessarily permanently occupied) such as those at Lepenski Vir, they are almost always associated with fishing as a major source of food.
The Neolithic culture and technology spread worldwide between about 8,000 and 4,000 years ago. With the new technologies of farming and pottery came the basic forms of most fishing methods known today.

Fishing may even pre-date the development of modern humans. There is a controversial proposal called the aquatic ape hypothesis which proposes that the ancestors of modern humans went through one or more periods of time living in a semi-aquatic setting and that they gathered most of their food from shallow coastal or other waters before their descendants returned to a more land-based existence.
