海狸工程师

2010年10月28日 | 标签:

Discovery拍的这部纪录片我是上半年看的,特别喜欢,因为此前我一直对它奇特的筑坝行为非常着迷,这部纪录片回答了我的不少疑问。据说目前海狸的筑坝长度记录是1200米,由此可见坝主的工作量和耐心。上个星期又下载了这部片子的高清版

这部纪录片在我眼里还是一部风光片。小小的海狸把一条小溪变成了池塘,“人”为制造了一个生态环境,使周边许多动物受益,那池塘的景色美极了。片中还记录了这个池塘的四季变化,可见其间凝聚了多少摄制人员的心血

看完这部纪录片我有2个疑问:

1) 这个海狸生活在池塘中,为何称为海狸,不叫河狸?

2) 海狸为什么会筑坝?这种能力是根植于基因里的本能吗?

本能是不需要学习的,它对生存极其重要。比如我们生下来后,就会主动找奶吃,会吸吮和吞咽。而我们另一个重要的能力:语言,就不是本能。如果一个孩子出生后,置于一个没有语言的环境,他是不会自己开发一个语言体系的。人类是目前唯一拥有完善的语言体系的物种,而且我们的脑中还为此配套了一个语言中枢,负责掌管文字的输入以及输出。它是一个复杂的系统,如果这个系统受损了,就会出现一些与之伴随的奇怪现象:有时候病人可以读出纸上的字,但不知道这些字的意思;有时候知道这些字的意思,却读不出来

回到刚刚的那个问题,海狸的这种本领是本能还是后天学习的?我个人倾向是后天学习的,因为它看上去太高级了。为了解决这个疑问,也许我们可以尝试让一个刚出生的海狸宝宝在脱离它的父母的环境中长大,然后观察它成年后有没有筑坝的能力

如果这种能力是后天学习的,那它一定是一代代的父母传授给他们的孩子的。而那第一只海狸是如何想到筑坝的呢?哎,真的不可思议。最好不要告诉我那是神的旨意 ^_^

自然界里难以想象的事太多了,比如:蜜蜂筑巢、蜘蛛织网、蚂蚁分工,等等等等,精巧的出乎人类的想像,而事实证明这就是本能,而不是依赖后天的学习

人是一个高级的动物,尽管个别器官不一定有其它动物的发达,可我们有一个非常复杂的大脑,充满了善与恶的冲突。但有一点在人类和动物之间还是相通的,那就是“爱”,比如对“情人”或“子女”的爱,因为“爱”是本能,至少我这么认为

    我觉得动物比人类单纯得多,人类智力高,所以更贪婪更凶狠更自私,至少在贪婪这点上,人类那可是所有生物里遥遥领先登峰造极的,一切都是造物所为吧,哎,我对人类这个罪恶的贪婪物种持悲观态度,但愿我们的智力能应付我们的贪婪吧

    @大宝

    如何应付人类的贪婪,真是个难题

    个人道德上克制?宗教信仰或法律?

    还好,人还会反思,知道有时自己错了.而且法律也在不断的完善,有些潮流不可阻挡

    所以,有时候,我还是比较乐观的

    前几天,这只上了周刊封面的狗真的感动了我,同你给的那个链接一样感人

    看那些图片很开心,然后再看你的文字头有三个大。。
    你我的区别不在血型。您是深究到底玩命较真的研究型思维,很适合你搞医学。
    我不求上进一贯,您就别笑我了哈

    能开心就好

    这两天在写一篇和血型有关的短文。我一直感觉血型和性格之间存在某种联系,就像部分女生坚信星座和性格、命运之间存在联系

    B型人被兴趣左右,我也一样。这些兴趣从年少时一直伴随着我,到现在我还坚持关心宇宙的命运,一集不落的在看discovery拍的探讨宇宙的起源、结局的纪录片。但B型人缺乏脚踏实地的精神

    你把一本书给读完了,很佩服的啊

    不负责任纯凭感觉的说,血型和思维方式无关,但和情绪模式有关。
    我读的,那也叫一本书,,,哪天你把《战争与和平》朗读完,俺才会说佩服佩服的。嗯。

    过两天,我的《血型》系列就要出来了,这两天太忙,没时间把写在纸上的字输进电脑里,有些地方还得改动

    到时候我们再探讨探讨 :)
