Animal experiments and drug safety Scientists say that banning animal experiments would mean either an end to testing new drugs or using human beings for all safety tests Animal experiments are not used to show that drugs are safe and effective in human beings - they cannot do that. Instead, they are used to help decide whether a particular drug should be tested on people. Animal experiments eliminate some potential drugs as either ineffective or too dangerous to use on human beings. We have 4 possible new drugs to cure HIV.
Share1 Shares The intelligence of animals is an interesting and varied subject. However chickens have been shown to have a remarkably sophisticated way of communicating.
In one experiment the call of a chicken that had found food was played to a bunch of domesticated fowl. Rather than simply celebrating as expected, the chickens reacted rather differently, instead articulating that food had been found to each other.
It was also discovered in the same experiment that chickens were able to differentiate between corn and regular rations using specific calls, again something it was believed only primate species could do.
This means that chickens are actually able to communicate a vast amount of differing information via a variety of calls, from warning each other about predators to alerting other members of their species to where food is.
Not bad for a creature we consume mostly in bucket form. Despite this, in experiments, pigeons have been shown to possess a cognitive ability that is considered essential to our own intelligence: For example, if shown a picture of two cars and one of a car and a truck, a person could easily recognize that one picture shows things that are the same while the other does not.
In an experiment using a touch screen computer, a pigeon was easily able to grasp this concept. For comparison sake, the exact same experiment was performed with baboons and a similar result was found.
In another experiment it was also discovered that pigeons also posses the ability to recognize themselves in a mirror with the same level of accuracy as a three year old child.
Self recognition is an incredibly rare ability only found in a handful of animals and pigeons, one of the most hated and reviled birds on our planet can do it better than our own children. Straight off the bat, though normally considered solitary creatures, certain species of spider are incredibly sociablecable of working together in groups of several millions to construct giant, tree sized webs.
When tasked with crossing a body water, the spider would leap or swim depending on the distance. Now this is where the experiment gets freaky: Even more terrifying is that the spider was able to respond to both negative and positive feedback and alter its approach accordingly.
Just soak that in, spiders are both capable of working together to achieve a singular goal and responding and learning from negative experiences.
So the next time you try to kill one and fail, you may have just made it stronger and more able to sneak up on you in the future.
In one experiment a fish was put into a tank with a net in it that had a small hole. After learning where the escape route was the fish was removed. A year later, when dropped back into the same tank the fish was immediately able to recognize its surroundings and escape.
Even more amazing still is that fish taken from the wild, when dropped into a tank full of fish that have never seen the open ocean, are able to teach their captive brethren how to recognize predators and survive on their own. In fact, the raccoon was actually supposed to be the standard, go-to lab animal but scientists found them too difficult to keep in cages because they kept escaping and stealing things.
In one experiment raccoons were placed in direct competition with rats, dogs and children. The experiment was simple, the animals and children had to recognize which of three light bulbs was going to turn on after a brief delay. Though dogs were able to do so with a delay of 5 minutes compared to raccoons paltry 25 seconds, the raccoons were able to do so while not even looking at the light bulbs, something only the children were also capable of.The existence and nature of emotions in animals are believed to be correlated with those of humans and to have evolved from the same lausannecongress2018.coms Darwin was one of the first scientists to write about the subject, and his observational (and sometimes anecdotal) approach has since developed into a more robust, hypothesis-driven, scientific approach.

The National Anti-Vivisection Society, founded in , is the world’s first body to challenge the use of animals in research and continues to lead the campaign today. There has been a long-standing community interest in the welfare of animals used in scientific research which has led to governments in many countries introducing animal protection legislation.
Advancing Science Without Harming Animals NAVS is dedicated to ending harmful, flawed and costly animal experiments through the advancement of smarter, human-relevant research and the promotion of animal-friendly changes to laws and policies.
Frankenstein may be a work of fiction, but these experiments are real. For decades, scientists have been tweaking the genes of animals to give them desirable (and sometimes just plain bizarre) traits.
