29、在此间十分相似。也许动物在适应适应环境变化时进化了？这虽然只是一环境变化时进化了？这虽然只是一个想法，但足以激励达尔文去寻找更多的个想法，但足以激励达尔文去寻找更多的证据证据。When the Beagle reached the Galpagos Islands in 1835,Darwin saw a variety of new species,but it was the birds that interested him the most.Darwin noticed that there was a difference between the finches on each of

36、出版，并立即引起了轰动。许多人许多人拒绝拒绝相信相信包括包括人在内的所有生命都是从更低级的生命形式进人在内的所有生命都是从更低级的生命形式进化而来的。他们感到震惊。但是达尔文的科学研究是化而来的。他们感到震惊。但是达尔文的科学研究是如此如此具有说服具有说服力，力，以至于以至于越来越多的人开始相信他的理论。越来越多的人开始相信他的理论。如今，物种起源被认为是有史以来最为重要的著作之一。它如今，物种起源被认为是有史以来最为重要的著作之一。它彻底改变了人们对于地球上生命的看法。而这一切都始于彻底改变了人们对于地球上生命的看法。而这一切都始于“猎犬号猎犬号”的探索之旅。的探索之旅。1.be first
