Do they have feelings ants?

This question posed in BBC Focus has puzzled some people, and it seems that some animals behave according to their emotions, but ants have complex emotions like love, anger, or empathy, but they approach things they find pleasant or unpleasant avoided.


They can smell with their antennae, and so follow tracks, find food and to recognize their own colony. His exoskeleton has sensory hairs on the outside, but you probably can not feel the hurt inside, so pests can destroy them if they can get without touching the sensors.

Each ant brain is simple, contains about 250,000 neurons, compared to the billions that humans possess. However, an ant colony is as big as many mammals collective brain. Some have speculated that an entire colony could have feelings.

Why women talk more than men ?

Or maybe the question is : why women never shut up ? Well in a nutshell, is not having much to say, but because of a protein in their brains .

As is well known , women say about 20,000 words a day , 13, 000 more than men . Research by the University of Maryland in Baltimore , USA , explains why women talk more .
It is because they have high levels of FoxP2 protein in the brain , also known as " protein language " according to the study published by the Journal of Neuroscience.
The researchers analyzed ten children aged between three and five years . The girls were 30 % more protein than boys Foxp2 , and a key area for the brain to develop the language of human beings.
Other studies have shown that girls learn to talk earlier and more quickly than boys. They produce their first words and sentences before, have larger vocabularies and use a greater variety of types of sentences than men of the same age .
However, Simon Fisher, one of the members of the team that identified the protein Oxford warned that they should not draw important conclusions from the study of such a small number of children .

Why when we are hungry our stomach makes noises?

Typically, these surrounded by friends or worse with someone you like, in total silence and that he does bear! Happens to your guts start to roar
But it happens to everyone and usually relate to being hungry, but why quésucede?


By contractions between the stomach and intestine, called Rumbling correctly. And although these happen all the time, the symphony is compounded when we have no food in the stomach why?
According to BBC, the digestive process in the stomach contracts to mix the food with gastric juices to push food into the intestine also continues to contract to continue with the process.
When no food the stomach and intestines take what is air. That echoes in the empty space producing a bigger sound.

They think Europe is the origin of the dog

For years , scientists have been intrigued by the origin of man's best friend .
The oldest dog fossils known from Europe . But DNA studies have pointed to East Asia and the Middle East. Now, a comprehensive DNA study suggests that dogs originated in Europe makes 19000-32000 years.


Experts praised the new study but warned that will not end the debate.

Scientists generally agree that the dog came from the wolf to become the first domesticated animal. Their ancestors wolves began to associate with humans, perhaps attracted by food in garbage dumps and debris left by human hunters pets. During this process were taming and scientists believe that humans find them useful for hunting and guarding . For a very long period in the human environment, the wolves were gradually becoming the first dogs.

The most recent attempt to determine where this transition occurred was published online Thursday by the journal Science.

The researchers collected DNA samples from 18 ancient fossils of creatures like wolves and dogs that lived 36,000 years ago in Argentina , Belgium, Germany , Russia, Switzerland and USA. They compared the genetic material with modern samples of 49 wolves in North America , Asia , Europe and the Middle East, 77 dogs with a wide variety of breeds , and four coyotes.

The DNA of modern dogs showed similarities to the genetic material of European antiguosespecĂ­menes and modern European wolves , the researchers reported .

The first dogs evolved partnering with hunter-gatherers rather than farmers , because obviously dogs appeared before agriculture , they said.

" Now , based on genetic evidence , there are three hypotheses on the origin of dogs ," said Robert Wayne , University of California at Los Angeles, one of the study authors.

He said his results suggest rather that eastern Europe Asia or the Middle East. He said the kind of wolf that originated the dog has died .
Olaf Thalmann of the University of Turku in Finland, another author , said that does not mean that Europe is the only place where the dogs came . "We came to the conclusion that Europe played an important role in the process of domestication ," he said in an email
