LONDON， June 7 (Xinhua) -- Researchers have found that archerfish is able to learn and recognize faces with a high degree of accuracy， which is an impressive feat given this task requires sophisticated visual recognition capabilities， according to a study published Tuesday in the journal Scientific Reports.
Being able to distinguish between a large number of human faces is a surprisingly difficult task， mainly due to the fact that all human faces share the same basic features.
"Fish have a simpler brain than humans and entirely lack the section of the brain that humans use for recognizing faces. Despite this， many fish demonstrate impressive visual behaviors and therefore make the perfect subjects to test whether simple brains can complete complicated tasks，" said Dr. Cait Newport from University of Oxford， one of the authors of the study.
Researchers from University of Oxford and the University of Queensland tested this idea on fish， which has smaller and simpler brains， and with no evolutionary need to recognize human faces.
Archerfish is a species of tropical fish well known for its ability to spit jets of water to knock down aerial prey.
In the study， they were presented with two images of human faces and trained to choose one of them using their jets. The fish were then presented with the learned face and a series of new faces and were able to correctly choose the face they had initially learned to recognize. They were able to do this task even when more obvious features， such as head shape and color， were removed from the images.
The fish were highly accurate when selecting the correct face， reaching an average peak performance of 81 percent in the first experiment， as they picked the previously learned face from 44 new faces， and 86 percent in the second experiment， in which facial features such as brightness and color were standardized， according to the study.
The fact that archerfish can learn this task suggests that complicated brains are not necessarily needed to recognize human faces. "Humans may have special facial recognition brain structures so that they can process a large number of faces very quickly or under a wide range of viewing conditions，" said Newport. Enditem
Gennaro Gattuso's debut as AC Milan coach ended in nightmarish fashion when goalkeeper Alberto Brignoli equalized in the fifth minute of stoppage time to earn Benevento Calcio its first ever point in the top division with an improbable 2-2 draw on Sunday.
Ten-man Milan was protecting a lead when Brignoli came forward for the final play of the match at Stadio Ciro Vigorito in Benevento and scored with a long Karl Malone Kids Jersey , leaping header following a free kick.
"It's difficult to describe," said Brignoli, who is on loan from Juventus. "I was thinking, 'It's 2-1, the 95th minute, we have nothing to lose.' I went up there, closed my eyes and jumped."
The last goalkeeper to score in Serie A was Massimo Taibi back in 2001 with Reggina.
Benevento had lost all 14 of its matches for the worst start to a season in modern history among Europe's five major leagues. If Benevento had lost again, the southern club would have matched Brescia in 1994-95 for the longest losing streak in Italian league history.
"It would have been terrible to lose this, as we've lost so many at the last second that we really didn't deserve to," Brignoli said. "Today we got some of that (luck) back. We've shown that we can play against anyone and just need the incidents to go our way."
Gattuso, a former stalwart in midfield for Milan, was hired to replace the fired Vincenzo Montella on Monday.
"It hurts. A knife wound would have been better than this goal," Gattuso said. "We're Milan and we need to be better, because this isn't enough."
Milan opened strongly and Giacomo Bonaventura scored one goal — his first since January — and set up another for Nikola Kalinic after George Puscas' temporary equalizer for Benevento.
But Milan defender Alessio Romagnoli was sent off in the 75th after picking up his second yellow card for tripping an opponent.
Milan dropped to eighth with 21 points, after Fiorentina won 3-0 at home to Sassuolo and rose to seventh on goal difference.
Inter Milan later took the Serie A lead with a 5-0 win over Chievo Verona at the San Siro. Inter has 39 points after 15 matches, one more than Napoli and two more than Juventus. (Agencies)

China Southern Airlines flew two planes from Guangzhou and Shenzhen while China Eastern Airlines sent four from Beijing and Shanghai.
China Southern said 1,297 passengers have booked seats on its flights flying out of Bali between Nov. 30 and Dec. 7. China Eastern, on the other hand, has 1,480 reservations on outbound flights from Bali.
The International Ngurah Rai airport in Bali was closed on Monday due to the eruption of Mount Agung volcano. The airport only re-opened Wednesday afternoon and was subject to further closures depending on the weather and the movement of volcanic ash.
