参考答案：A
解析：[分析] 推断题型。 文中提到More recent threats to life forms are humans and their activities…Some of the more recent casualties of man's expansion have been the dodo，great auk，passenger pigeon，Irish elk，and Steller's sea cow，各种生物近期遇到的威胁更多来自于人类。……近期人类扩张所造成的一些受害者有：渡渡鸟、大海雀、候鸽、受尔兰麋鹿及Steller's海象。因此根据本文，我们能推断出人类是造成某些动物灭绝的原因，所以A是答案。
