The frequency range of dog hearing is approximately 40 Hz to 60,000 Hz, which means that dogs can detect sounds far beyond the upper limit of the human auditory spectrum. [3] n/a may be up to 100 million times greater than a human. n/a n/a n/a n/a n/a Human: red~650 nm to violet ~400 nm (or) VIBGYOR: 20 Hz to 20,000 Hz (or) Audio: n/a n/a n/a n ...
Additionally, larger dogs have a better sense of smell than smaller dogs. [7] A dog's nose is significantly colder than their body temperature. This makes it more sensitive to thermal radiation. Dogs can thus detect even weak levels of warmth. [8] Dogs are able to smell from birth and develops during the first two weeks of their life.
Dogs can smell explosives like landmines, and detect medical conditions including seizures, diabetes, and many forms of cancer -- with up to 98% accuracy. Inventor Andreas Mershin wants to ...
Charles Darwin wrote of the interaction between size and complexity of invertebrate brains: . It is certain that there may be extraordinary activity with an extremely small absolute mass of nervous matter; thus the wonderfully diversified instincts, mental powers, and affections of ants are notorious, yet their cerebral ganglia are not so large as the quarter of a small pin's head.
Then, other ants follow suit, with more pheromones released, creating a more refined path. Which then attracts even more ants. Lather, rinse and repeat, and pretty soon an optimal path is forged ...
Their ecological dominance has been examined primarily using estimates of their biomass: myrmecologist E. O. Wilson had estimated in 2009 that at any one time the total number of ants was between one and ten quadrillion (short scale) (i.e., between 10 15 and 10 16) and using this estimate he had suggested that the total biomass of all the ants ...
Ants as a colony also work as a collective "super mind". Ants can compare areas and solve complex problems by using information gained by each member of the colony to find the best nesting site or to find food. [2] Some social-parasitic species of ants, known as the slave-making ant, raid and steal larvae from neighboring colonies. [19]
Hu’s research team found in similar experiments, published in Biology Open in February 2022, that rafting ants consumed almost 43 percent more energy than ants on dry land. But the larger the ...
