Are Animals Getting Smarter
Thursday, January 31st, 2008Are animals getting smarter? Not long ago on Utube, I watched some amazing animal videos. In these videos you could see proof of the animal using cause and effect.
In one video, a raccoon was captured in a concrete cage, outside. The top of the cage was opened, but he was enclosed on all four sides. The raccoon, with a lot of effort, was able to lean a broken tree limb, which was lying in the bottom of his cage, in one of the corners of the cage. He then used the broken limb as a ladder and climbed his way out to freedom.
In another video, there was a wild bird, (I don’t recall the species), but he was standing on a pier looking out into the water. Nearby the wild bird on the pier were some bread crumbs – instead of eating the bread crumbs, the wild bird picked up the bread and walked to the end of the pier, dropping the bread into the water. He then waited patiently, never taking his eyes off of the bread. The wild bird was quickly rewarded for his patience when a fish came to the surface to feed on the bread. With no hesitation the bird swooped down and gained his dinner of a nice, juicy fish.
This shows extraordinary ability to apply insight to problem-solving. This bird had to think his plan through, and imagine what the outcome would be. It was amazing to watch.
If you question the intelligence of animals, think back on your pets. They understand your commands, read your moods, and knows how to manipulate you to get what they want.
PBS had a ’special’ on called, “Inside the Animal Mind.” Researchers studying the behavior of Ravens noticed they have the ability to solve difficult puzzles, such as untangling a knotted string to free up a tasty treat, or figuring out how to steal fish by hauling in an angler’s untended line.
Dr. Irene Pepperburg of the University of Arizona, began systematically studying Alex and several other African Greys, parrots that are remarkable mimics, to understand avian intelligence. The study showed that Alex does more than just reproduce the sounds of human speech, but that Alex actually understands meanings. For instance, Alex can name more than forty objects and understands the concepts of “same,” and “different,” “absence,” “quantity,” and “size.” Alex has mastered tasks once thought to be beyond the capacity of all but humans, or certain non-human primates.
Researchers also agree that animals share some emotional characteristics with us; like stress. Like humans, many animals can be harried and stressed out, with sometimes serious health consequences.
In a study conducted by Stanford University, for three months each year, Robert Sapolsy travels to East Africa’s Serengeti Plain to examine the baboon. By measuring the hormones found in each baboon’s feces, Sapolsy’s team has been able to show that baboon troops are high-stress societies, with higher-ranked individuals maintaining order by intimidating lower-ranked troopmates. Sapolsy says, “Baboons and us are surprisingly similar . . . they can devote a large part of each day to making each other absolutely miserable with social stress.”
The high-stress levels also showed that it can cause serious health consequences. Stressed-out mothers, for instance, have more problems producing healthy offspring. Stress can also effect learning and memory in the animals, much like in humans.
Animals also exhibit a consciousness similar to people. Bees can create “mental maps,” images they hold in their minds that allow them to navigate around their environments by picturing themselves there.
Chimps and elephants show an awareness of death. They grieve when a family member dies. Elephants will hang around the bones of long-dead relatives – seeming to ponder the past and their own future. Are these behaviors enough to give animals membership in the consciousness club?
Researchers are actively debating over that question now. “Consciousness is one of the hardest things to define and study,” says Pete Chernika, an Austrian researcher who has studied consciousness in dolphins and other animals.
Dolphins are able to recognize themselves in a mirror. They also exhibit a keen awareness of the status and identity of other dolphins in their highly social groups. They know who their mom is, who their leaders in the pod are, and how they should behave around different individuals. Chernika says, “The more people study other animals, the more we realize how hard it is to define consciousness – and how hard it is to decide who has it, and who doesn’t.
