What makes us who we are? This question has two different answers. One is the environment that surrounds us when we grow up, and the other is our genes (基因). In English, this is called the “nature vs nurture debate(辩论)”. Nature means genes, and nurture means environment, including the people around you.

There is a famous saying: “Give me a child until the age of 7 and I’ll show you the man.” Now, there is a scientific research to support this famous saying.

They watched small birds in new environments, and wrote down how much they explored(探索). Birds that grew up with very outgoing birds were more outgoing themselves. Scientists at the universities of Exeter, UK and Hamburg, Germany did studies on birds. They found that their personalities(个性) were affected most by the birds around them when they grew up – more so than genes.

Nick Royle from the University of Exeter in the UK said the research was surprising because it shows that “for these birds, personality is mainly determined(决定) by environment.” However, human personalities are a lot more complicated than birds, so there is much we still don’t know. The nature vs nurture debate will continue for a long time, if not forever.
