Imagine that an alien species landed on Earth and, through their mere presence, those aliens caused our art to vanish, our music to homogenize, and our technological know-how to disappear. That is effectively what humans have been doing to our closest relatives—chimps (大猩猩).

        Back in 1999, a team of scientists led by Andrew Whiten showed that chimps from different parts of Africa behave very differently from one another. Some groups would get each other’s attention by rapping branches with their knuckles (指关节), while others did it by loudly ripping leaves with their teeth. The team identified 39 of these traditions that are practiced by some communities but not others—a pattern that, at the time, hadn’t been seen in any animal except humans. It was evidence, the team said, that chimps have their own cultures.

        It took a long time to convince skeptics that such cultures exist, but now we have plenty of examples of animals learning local traditions from one another.

        But just when many scientists have come to accept the existence of animal cultures, many of those cultures might vanish. Ammie Kalan and her colleagues have shown, through years of intensive fieldwork, that the very presence of humans has eroded the diversity of chimp behavior. Where we flourish, their cultures wither. It is a bitterly ironic thing to learn on the 20th anniversary of Whiten’s classic study.

        “It’s amazing to think that just 60 years ago, we knew next to nothing of the behavior of our sister species in the wild,” Whiten says. “But now, just as we are truly getting to know our primate (灵长类) cousins, the actions of humans are closing the window on all we have discovered.”

        “Sometimes in the rush to conserve the species, I think we forget about the individuals,” says Cat Hobaiter, a professor at the University of St. Andrews. “Each population, each community, even each generation of chimps is unique. An event might only have a small impact on the total population of chimps, but it may wipe out an entire community—an entire culture. No matter what we do to restore habitat or support population growth, we may never be able to restore that culture.”

        No one knows whether the destruction of chimp culture is getting worse. Few places have tracked chimp behavior over long periods, and those that have are also more likely to have protected their animals from human influence.

        Obviously conservationists need to think about saving species in a completely new way—by preserving animal traditions as well as bodies and genes. “Instead of focusing only on the conservation of genetically based entities like species, we now need to also consider culturally based entities,” says Andrew Whiten.

解析：D。根据题干中的Andrew Whiten’s team可定位到第二段第一句。该句指出，早在1999年，由安德鲁·怀顿带领的科学家团队就发现，非洲不同地区的猩猩彼此之间的行为千差万别，并列举出两种不同的沟通方式。D项与此内容相符，其中Different chimp groups对应定位句中的chimps from different parts of Africa，differ in their way of communication是对原文第二段第二句中所举例子的概括总结，故D项正确。

错项排除：第二段第二、三句中举例说明了不同种群的猩猩各自有独特的沟通方式，但并没有说明这些沟通方式是高度发达的（highly developed skills），也没有说这些沟通严重依赖于肢体语言（rely heavily upon their body language），故A、B项排除。原文中并未就猩猩的行为与人类的行为作比较，故C项错误。
