However, signals that evolved for one purpose may develop other functions. Some porpoises appear to use rhythmic patterns of "echolocation" clicks as communicative signals. When a whale makes a low-frequency sound for communication, the sound may echo from the seafloor and possibly provide the ...
Some of these hunters have developed echolocation abilities to help them find their prey and locate any obstacles. Echolocation is a very simple concept: The whale emits a series of clicks (or other sounds) from its mouth or from organs in its head, and the sound waves travel out in the ...
Bats use echolocation, which are sound waves that travel in the air till they hit an object and bounce back to the bat so it can in a sense see what is around him by knowing how long the wave took to get back. Ultrasound works similarly to bats echolocation. It uses high frequency ...
Our individuality allows for things like culture and tradition to develop and establish a sense of what it means to be human. Perhaps the variance of personalities within octopuses allows them to develop a sense of culture in a similar way to humans. However, to determine that we would have ...

To address this problem, we need to develop a mathematical theory for representing common sense knowledge that can be implemented in computer software. We start off with a set of primitive objects in the world which I will call S. A “term” is the technical term for a “mode...
No matter what kind of penis its parents had, or what type of penis it had the previous mating season, a barnacle in rough water will develop a short, stout penis. Minding the Neighbors How densely packed barnacles are in an area also affects their penis shape. Mo Riza/Flickr The ...
The popular expression of being "blind as a bat" really doesn't hold true. Some bats that have the most advanced type of echolocation appear to have traded UV vision for exquisite hearing, and all bats that do not echolocate but live in caves have also lost UV vision. This suggests that...
Biologists are used to convergent evolution, like the streamlining of dolphins and sharks or echolocation in bats and whales—animals from separate lineages have similar adaptations. But convergent evolution of algorithms? Either all these collectives came up with different behaviors that produce the ...
Echolocation is an adaptation bats use to How do hominids differ from monkeys and apes? Are bats mammals or are they members of the class Aves? How do monotremes mate? How do hominids differ from apes? How are dolphins and chimpanzee similar? Are fruit bats placental mammals? How do mon...
