What makes humans smarter than other animals? We’ve got a bigger brain, of course. But when it comes to brains, is bigger always better?

Traditionally, scientists have thought that humans’ superior intelligence derived(源于)mostly from the fact that our brains are three times bigger than those of our nearest living relatives, chimpanzees. People even used to believe that because men have slightly larger brains than women that men are smarter.

This, however, is not the truth. Scientists at University College London in the UK have found that brain organization, and not brain size, is the key to the superiority of human intelligence, reported Live Science.

Through millions of years of evolution, our ancestors were constantly pushed to get smarter so that they could meet the demands of new environments. However, holding this growing intelligence in increasingly large brains was not the best choice because bigger brains require more energy to power. “This is when reorganization may come into play, ”said Christophe Soligo, a member of the London research team.

In the study, scientists looked at the brains of 17 species of primates(灵长目动物), including monkeys, apes and humans. They found that in the process of evolution, brains didn’t keep growing as a whole. Certain regions of the brain grew prior to others in response to species’ needs, and in this way they could make the best use of their limited brain space.

For example, when early humans were struggling to survive, the brain region in charge of using tools and finding food grew in size more than other regions. But in modern times, the prefrontal cortex(前额皮质)—the region in charge of social cognition(认知), moral judgments and goal-directed planning—grew more than the rest of the brain.

Think of the brain as a room. If a big room is poorly organized, it doesn’t necessarily store more stuff than a smaller one.

Paul Manger, professor at the University of the Witwatersrand, South Africa, explains this principle using the example of whales. He told Scientific American: “Whales have big brains, absolutely. But if you look at the actual structure of the brain, it’s not very complex. Brain size only matters if the rest of the brain is organized properly. ”

The purpose of a letter of application(求职信)is to help you to“sell”yourself. It should state　　the job you want, and should tell what your abilities are and what you have　　. It should be simple, human, personal and brief without　　out any necessary facts.

In writing a letter of application, keep in　　that the things a possible employer is most　　to want to know about are your qualifications(条件), your achievements and your aims. The opening paragraph is perhaps the most important part. 　　the first few sentences fail to　　the reader’s attention, the rest of the letter may not be　　at all. Try to key your opening remarks to the needs or interests of the employer not　　your own need or desires. For example, instead of beginning with “I saw your　　in today’s newspaper”, you might say“I have made a careful　　of your advertising during the past six months”or“I have made a survey in my neighborhood to find out how many housewives　　your product and why they like it. ”

Try to　　generalities(概述). Be clear about the kind of job for which you are now　　. College graduates looking for their first positions often ask“What can I　　in a letter? Employers want experience—which, naturally, no　　has. ”The answer is that everything you have ever done is　　.

It is important to write a good strong closing for your letter. 　　a specific request for an interview or give the possible employer something definite to do or expect. An excellent　　is to enclose(内附)a stamped, self-addressed envelope with your letter. That makes it　　for a possible employer to get in touch with you.
