Many animals, including humans, are traditionally selfish creatures. If some organisms were as self-centered about parenting as they are about other lots in life, there would arguably be much fewer offspring in this world. Now researchers have identified brain mechanisms that help prospective parents have a change of heart and bond with their children.
How exactly is is that the nose can differentiate smells, focusing on one scent in particular? Researchers attempt to answer this question.
Researchers have recently discovered that not only does a species of deep sea octopus live the longest among all known cephalopods, it also has the longest developmental period for any known organisms - a whopping four years. And while those octopus juniors are taking their sweet time to hatch, mamma vigilantly watches over them for the WHOLE TIME.
In the animal kingdom, it has long been seen that even newborns know to fear certain predators or situations long before they could have possibly learned for themselves about that threat. This has baffled researchers for years, especially among those who scoff at the notion of intrinsic, or "pre-programmed," fears at birth. Now, a new study suggests that these initial fears are not intrinsic, but shared by their mother through odor alone.
Even the smallest of floods may seem like the wrath of the heavens from the perspective of ants. Researchers have found that to survive these cataclysmic events, ant colonies clump into a living arc that can ride on flood-waters until dryer land is found.
The next time you see a lab mouse going nowhere fast on an exercise wheel, don't feel so sorry for him. Recent research has found that mice actually enjoy running the wheel, and even wild mice will do it.
How patient a primate is may depend entirely on how it has evolved. Primates with larger bodies appear to be more willing to wait for large rewards, compared to smaller species who prefer immediate gratification. One researcher claims that these observations may help us better understand the patience of humanity as well.
Researchers are finding more concrete evidence that humans are not the only species which pass traditions down from generation to generation, but humpback whales and vervet monkeys also learn behavior from their peers.
