奇树蚁容

柳宗元诗赞柳江：“　岭树重遮千里目，江流曲似九回肠。”登上马鞍山顶，俯瞰柳州全景，旖旎风光，尽收眼底。柳北被蜿蜒碧绿柳江包围着，宛如一座天然盆景，非常壮观。

柳江南岸江堤石墙上生长着很多植物，数江滨公园最盛。难以想象的是一颗小小的榕树种子，竟然能在石墙缝隙中生根发芽，并根深叶茂。榕树根系十分发达，石墙上的树根穿石绕墙。石墙上有很多缝隙，树的气根会自己找适合条件的缝隙钻进去生根，这些气根是如何寻找地方生根的呢？恐怕要植物学家才能做令人信服的解释。

石墙上的树有一个共同的特点：矮壮，地上的同种树高大，两者为什么有这样明显区别呢？可能石墙树的营养物质大部分供给裸露在外面的根系，因为气根更需要生长，以保证石墙树自给。我想，石墙树生长条件恶劣，所以长得慢，材质密度可能要比在地上的同种树材质密度大些，读者认同我的观点吗？

有的石墙树直径达十几厘米，却很矮，像是同类的侏儒，这是生长条件所决定的。如果形容地上的树是“高富帅”的话，那么石墙树就是“矮矬丑”。石墙树根系粗细不等，它们像蛛网一样紧紧贴在石墙上。纵横交错，挺拔坚韧；千姿百态，蔚为壮观。生命的顽强和张力在石墙树身上得到完美体现，这是石墙上一幅奇特的壁画，江堤上的另一自然景观。

有了石墙树，江堤坚如磐石，百年永固。不会因为风化和自然灾害而崩塌，就像植被丰富的地方，不易水土流失一样。这是石墙树一个重要作用，也是大自然的对龙城的造化。

我天天在红光大桥西岸旁游泳，此处江堤石墙上也长着一棵小树。前天清晨游泳起水后，在这棵小树树荫下更衣，猛然发现树干上有一行蚂蚁在忙碌着，我十分好奇，顺着蚂蚁行进路线细心观察起来。树干上的蚂蚁通过树干在石墙挤出的裂缝，进入到石墙上的花台，花台泥土有一个蚁穴出入口。我猜想，蚁穴很可能就在花台泥土下面。

石墙水泥栏也有一队蚂蚁，有约十只工蚁正在搬运一个小蜗牛，它们有序的围在蜗牛四周，有一只兵蚁也来帮忙，齐心协力把这只蜗牛拉进蚁穴。在前面的工蚁是如何使力的呢？他们的前肢是如何抓紧光滑的蜗牛壳呢？难道也有像壁虎脚掌的吸盘？在行进前方的工蚁，它们头部面对蜗牛，等于是倒行，想象得出在行进前方的工蚁肯定要比在后面推行的工蚁费力。这只蜗牛的重量不知是工蚁的多少倍，我简单估算一下，把十只工蚁体重加起来，也没有蜗牛重，可见蚂蚁的力气非常大，它举重若轻，可以拉动几倍于自己体重的物体，它们是如何做到的呢？它们惊人技能使人类汗颜。

这只蜗牛是活的吗？想到这里，我找到一个空蜗牛壳，放到蚂蚁行进队伍中，蚂蚁们对这个蜗牛壳置之不理，显然，蚂蚁对食物发出的特殊气味有很强的识别能力，它们知道这是一个空蜗牛壳，里面没有令它们垂涎欲滴的美食。蚂蚁的食物辨别能力比人类强，至少蚂蚁不会因为食物中毒。

蚂蚁如何享用蜗牛这道美食呢？蜗牛外壳坚硬无比，蚂蚁想从外壳入手，简直就是蚍蜉撼树，看来只能从蜗管进入，它们怎么把佳肴从蜗管中取出来呢？这是一个十分有趣的问题。

蚂蚁是一种有社会性的生活习性群体，是一个和谐社会，而且等级森严，分工明确，每一个成员都清楚知道自己的责任和义务。一只工蚁是不会擅自享用食物的。我想，可能是工蚁从蜗管进去给蜗牛注射蚁酸，待蜗牛麻醉后，再用牙齿切割蜗牛与蜗管的粘连处，尔后用群体力量把蜗牛肉拉出来。当然这只是我的想象，谁知道蚂蚁世界内幕呢？

还有两只工蚁扛着不知从哪里找到小昆虫的翅膀，它们健步如飞，姿态优雅。我观察它们的时候，可能它们也正好奇的瞥视着我这个巨人，并调皮地对我挤挤眼，友好地对我微笑着说：“hi！我们正忙着呢，请别打扰我们，thank you！”

I ask you a question to test your reading level, but didn't claim it is my idea. That short article was written by Diamond too, who is stealing from whom?

If you have no knowledge about a question, don't be so eager to reply. Answering without thinking is not a good quality of a researcher.

Apparently, you didn't past that test.

bye-bye.

omg, from this reply I could see you seldom read popular fine books or even some essays in the fields that are related to your major, just as luguo does.

If you do a research, the first step would be to search literature. This is the most important step, because if you have no idea what other advanced researchers are doing, if you have no idea where the trend in your field is going, how could you be competitive? Picking up a misspelling wouldn't help you anything.

Doubt as freely as you may, but that
your hypothesis is not even testable...
scares the hell out of me.

A fine researcher is usually a fine philosopher. Read the following quote. I think our discussion should end right here. So long!

引用 2013-7-22 11:27 PM: waspking: to relax and share. to learn a few things, but not in a serious (academic) way.
that is exactly what I'm saying. If you focus on RNA and Rnai, that is a bit too heavy and too academic.

I just need to thinking freely, and forget about the small details.

it is home sapiens. My bad.

picking up a typo doesn't make you have an answer to my question.

On the hand, it proves exactly my point again that i emphasized in my last posts: to be able to think is more important than to grab a few facts.

RNA and Rnai things are exactly what i mean by saying that facts are easy to obtain by thinking is hard. You might also think you know too much too about life to come here to exchange ideas with other netters. Why you came anyway?

yes, but I had an impression that some of your understanding was wrong so there is no base to discuss anything (e.g. you said RNA was loose or something in one place talking about RNAi). I feel I know too much to join any discussion now so I did not read there.

muyu,

waspking,

Somehow I know you wouldn't finish the book, because your are too busy with earning a living.

引用 2013-7-22 06:41 PM: waspking: i read some, as a reference. no time to talk about evolution now...you should just go and take an online course.
online course？ you mean what? university of phenix? In case of that, I wonder who is going to teach whom.

I mean to talk about evolution at a higher thinking level, not merely reciting some facts written in a textbook.

If you read Luguo's thread about evolution at baihua, you would know that facts are easy to obtain but thinking is hard!

对不起我不研究蚂蚁，书很厚，估计6-7百页。如果是小蜜就会读几遍了。
