生命长河

River ofLife

生命——地球历史上最伟大的奇迹，孕育、变异、繁盛和衰亡的跌拓起伏，周而复始，生生不息。有一些类群盛极一时，却走向绝灭，凝固为化石；有一些默默无闻，但历经沧桑，繁衍至今。无论是逝去的还是鲜活的，渺小的还是巨大的，它们都是生命长河的见证者。

Life, the greatest miracle of our planet’s history.  It is born, varies, weakens, and is born again.  Some species flourished for a time, but have become extinct with no more than their fossilized remains left behind.  Others emerged quietly and have found a way to survive for countless generations.  Regardless of whether they have become extinct or are still existent, are infinitesimal or gargantuan, all of these organisms have borne witness to the flowing river of life.
