Echolocation is mainly found in toothed whales, such as dolphins and sperm whales, not their toothless cousins. The toothless-whale group -- which includes humpback whales, blue whales and many other species --
109K Learn about the physical and behavioral adaptations of dolphins. Discover the importance of their blowholes and echolocation abilities. Finally, explore how dolphins respond to danger and how their social behaviors help them survive. Related...
Bats, who hunt at night, use echolocation to find their prey, too. First, the whale has to produce a sound. Toothed whales don't have anything exactly like our vocal cords, although they have similar structures. It's thought that they produce their sounds in their nasal passages [source:...
Echolocation Orca whales use echolocation to communicate, hunt and navigate. Echolocation involves the use of sound and its echoes to give a whale a picture of the surrounding area. Echolocation also allows orcas to navigate past obstacles in some of the deepest parts of the ocean. Orca whales ...
1.3 Argument from evolutionary algorithms The second version of the evolutionary argument for the feasibility of machine intelligence does not attempt to parlay evolutionary considerations into a general assessment of how hard it would be to create machine intelligence using some unspecified method. ...

Based on this mechanism, hereditary traits that help organisms survive and reproduce become more common in a population over time. Such mechanisms of evolution work with the random variation generated by the mutation of the genetic code of organisms in the passage from one generation to the next....
