Sympatric speciation is the formation of two or more descendant species from a single ancestral species all occupying the same geographic location. Often-cited examples of sympatric speciation are found in insects that become dependent on different host plants in the same area.
Rice noodles are a type of semi-transparent pasta made from rice flour and water. Most are very long and thin, but you can also find flat rice noodles, as well. These noodles cook notably fast and can actually turn to mush if cooked for too long, so it's important to know how to cook them properly.
For other uses, see Noodle (disambiguation). Noodles are a staple food in many cultures made from unleavened dough which is stretched, extruded, or rolled flat and cut into one of a variety of shapes. While long, thin strips may be the most common, many varieties of noodles are cut into waves, helices, tubes, strings, or shells, or folded over, or cut into other shapes. Noodles are usually cooked in boiling water, sometimes with cooking oil or salt added. They are often pan-fried or deep-fried.
