When it comes to social behaviour,mammals are in a league of their own.Some birds may form pairs,or even cooperate to hunt,but the complexity (复杂性) of their relationships can hardly compare to those within a school of dolphins,a herd of elephants or a group of humans.What makes mammalian social groups different from a flock of starlings or a shoal of fish,is that in many cases the individuals could recognize each other.Although we may think that all elephants look pretty much the same,we can easily tell individuals of our own species apart and it has become clear through studies that the same is true of other species.Dolphins have their own signature whistles that act like “names”,and elephants can recognize and greet other individuals they have known but not seen for many years.This is something that only a few species of birds appear to be able to do.
Mammals in complex social groups not only recognize each other as individuals,but also they remember a lot of information about that individual.Social groups often rely on this memory—such as knowing who is dominant to whom,who is related to whom,and who has done what to whom in the past.It’s like remembering who you have lent money to or done a favour for,and who hasn’t repaid that money or has talked about you behind your back.You have to learn who to trust,who your friends are,and who to watch out for.
All this remembering goes on in a particular part of the brain called the neocortex (大脑皮层).If you compare the size of a mammal’s social group with the size of this part of the brain,you will find they are remarkably closely related.This area seems to take a long time to develop fully and animals in which it is very large take a very long time to grow up to adulthood.During this time,the youngster has to learn all the rules of social behaviour in their group and to piece together all the relationships between the group members:Knowledge that will be needed to avoid getting into trouble.

It’s a great sunny day,so it’s time to get out and enjoy the weather.Many of us would like to,but we have projects due,tasks that need to be done,people that we need to see,and money that needs to be made.
What if your company gave you that time off as compensation for the great effort that you gave to the team to finish a project on time?See,when it comes to teamwork,the main focus is for the team to work together.In a “winning” team there is an equal balance of people who have unique strengths and weaknesses.
Take the example of the Chicago Bulls of the 1990s.Michael Jordan was the greatest basketball player to play the game,but did they win a championship every year when Michael had played?No.It took a (Dtype) Michael Jordan to lead the team and control the outcome.It took a(n) (Itype) wild and energetic Dennis Rodman to keep the team fun and interesting.It took (Stypes) Scottie Pippin,Bill Cartwright,and John Paxson to support the team.And it took the (Ctype) analytical mind of Coach Phil Jackson to create a foundation for the players to play on.In the end they,the Chicago Bulls,were able to win six championships within eight years.
What is your team made up of?All Jordans?All Jacksons?All Rodmans?Or all Pippins,Cartwrights and Paxsons?It is you who can choose who’s on your team.Try finding the right people for the right job,and you will have a “winning” team every time!
