Both cats and dogs have served as mascots and pets during wartime , but while cats were useful for pest control, dogs had a rather different set of duties, including tracking, scouting, serving as sentries, and carrying messages into battle.
In the deep, dark ocean, many sea creatures make their own light for hunting, mating and self-defense. Bioluminescence expert Edith Widder was one of the first to film this glimmering world. At TED2011, she brings some of her glowing friends onstage, and shows more astonishing footage of glowing undersea life.
One can imagine life evolving again and again, crashing on the rocks of time and circumstance, until finally it hit upon just the right mutation rate—one that eons later would produce organisms and species and ecosystems.
On a National Geographic expedition to the Galápagos Islands, travelers witnessed something extraordinary: the birth of a sea lion. Even while in labor, the mother was unfazed by the presence of humans, delivering her pup on the beach with a nuzzle, a nudge, and a playful gnaw.Click here to learn more about the Galápagos Islands expedition.Click here to see more video highlights from the National Geographic - Lindblad fleet of expedition ships traveling around the globe.
SUMMARY: Books, books, beautiful books! This is a list of biology, ecology, environment, natural history and animal books that are (or will soon be) available to occupy your bookshelves and your thoughts.
Chimpanzees may reinforce social bonds by involuntarily mimicking a fellow chimp’s pupil size.
Like humans, chimpanzees possess a capacity to unconsciously dilate their pupils to match those of a conspecific, according to research published last week (August 20) in PLOS ONE. The results suggest this involuntary action likely evolved to help humans and chimps communicate sympathy and strengthen social bonds within groups.
In face-to-face interactions, people often involuntarily imitate each other’s facial expressions, eye blinks, or pupil size to convey empathy.
These physical cues help communicate emotions to both individuals in the interaction, facilitating trust and cooperation within groups. But precisely when and how these signals evolved isn’t clear
Conventional wisdom has long held that corals—whose calcium-carbonate skeletons form the foundation of coral reefs—are passive organisms that rely entirely on ocean currents to deliver dissolved substances, such as nutrients and oxygen.
Contagious yawning in wolves give researchers a glimpse at the roots of empathy.
Still, these theories don’t totally explain one of the more fascinating aspects of yawning: When we see someone else yawn, our chances of yawning go way up.
The leading hypothesis among scientists, Romero says, is that this contagious yawning is related to empathy—meaning an empathetic person or animal will feel tired when he or she observes another individual looking tired.
Forget swarms of nanobots taking over the world—if something is going to band together to rise against humans my money is on ants. Look at this video of them forming a chain to move something way bigger than any individual ant.
The Basenji also called the Congo Terrier is native to the Central African forest. Since ages he is used by the pygmies (thought to be the oldest of all humans) to hunt lions. Therefore the basenji is one of the oldest breeds of dogs.
