Walking Upright
研究人员发现人类开始直立行走的原因
Most of us walk and carry items in our hands every day. These are seemingly
simple activities that the majority of us don't question. But an
international team of researchers, including Dr. Richmond from GW's Columbian
College of Arts and Sciences, have discovered that human walking
upright , may have originated millions of years ago as an
adaptation 源于 to carrying 搬运 scarce 稀有的, high-quality 高质
量的 resources 资源. The team of researchers from the U. S., England, Japan
and Portugal investigated the behavior of modern-day chimpanzees as they
competed for food resources, in an effort to understand what ecological settings
would lead a large ape - one that resembles the 6 million-year old ancestor we
shared mon with living chimpanzees - to walk on two legs.
