is the process of preparing food by use of heat.
Cooking techniques and ingredients vary widely across
the world, reflecting unique environmental, economic,
and cultural traditions. Cooks themselves also vary
widely in skill and training.
Preparing food with heat or fire is an activity
unique to humans, and some scientists believe the
advent of cooking played an important role in human
evolution. Most anthropologists believe that cooking
fires first developed around 250,000 years ago.
The development of agriculture, commerce and
transportation between civilizations in different
regions offered cooks many new ingredients. New
inventions and technologies, such as pottery for
holding and boiling water, expanded cooking
techniques. Some modern cooks apply advanced
scientific techniques to food preparation.
