The main point of this article is to show the opinions between Stephen Jay Gould and Simon Conway Morris. Gould believes that if the Cambrian explosion was rewinded, then the outcome would be different and there would be less extinction. On the other hand, Morris believes that this is not the case. He says that everything happened for a reason and that we humans were meant to be the goal of evolution. The Cambrian explosion was an event over five-hundred years ago that occurred in the time frame of twenty million years. Twenty million years is a short time frame compared to how long eras can go for. The Burgess Shale are fossils from the Cambrian period that are located at the Canadian Rockies. The reasons why the Burgess Shale is so popular

Hox Gene and Cambrian Explosion

...classification of domains is used to categorize the different types of cells: bacteria, archea, and eukarya.  The names of periods and organisms and certain dates are often helpful in remembering or understanding events that occur in the natural history of evolution.  However, we do not expect you to know the names of all organisms mentioned nor all dates (you may find some of the sound attachments on complicated figures useful for review).  Those names and dates mentioned below are the ones to key on. The focus in this session is macroevolution which looks broadly at the time lines and changes over long intervals of time.  Remember that small changes over millions of years are the framework for evolving complexity from simplicity.    Summary of concepts and idea   An initial step in covering this material is an understanding of the different types of cells (prokaryotic, eukaryotic animal and plant), their differences, and their place in the phylogeny of life. 1. Information from pre-class reading, Bioflix animations and briefly summarized in class discusses the fundamental components of the prokaryotic and eukaryotic cells.  You need to know the differences and understand the basic functions of the cellular components as cells as they are the fundamental units of life. 2.

...文勇的新托福精选阅读(原黄金29篇)真题[2010年4月3日 5.8版本] 俺常常收到同学们的邮件,要我推荐各种各样阅读材料,问我iBT的复习资料中 Barron, Longman, Delta等等哪个更好。我其实很无奈---因为尽管这些机构很大牌,但大牌丝毫都不意味着文章“质量高”(比如你可以想想三鹿奶粉)---说这些机构的文章质量不高,并不是说文字写得不好,而是说这些文章的句子结构, 论述方式, 出题思路与ETS的并不一致(有时候甚至大相径庭):用这样的材料训练,实在是 事倍功半。 于是,我们实在应该去找找由ETS出的iBT文章来做:(我们能够找到的|由ETS编纂的标准iBT文章有) 1. OG[1]之中的13篇文章[2];(其中3篇为第三版OG之中的文章) 2. 13次(套)TPO[3]之中的3*13=39篇文章[4]; 3. 早期[5]报名之时ETS赠送的3篇在线测试题 4. ETS官方给出的模考软件之中抽出的1篇文章; 于是这个文档在我的一时兴起之下,出现了: OG拿在手上,可以一个个字的敲成电子版;TPO的所有考试都是在自己的计算机进行,于是可以一边花钱参加考试,一边截图与录像---再利用截下来的图片,逐个的敲下来;早期的ETS赠送的3篇在线测试题,我也恰好有电子版本;官方的模考软件稍微用点功夫,就能将文章提取并复制出来。虽然工作有些繁杂,但总算完成了所有文章的敲打工作。再花了些时间,把这53篇文章都做了答案,附在文章的后面。(由于TPO之中有3篇文章与OG中完全重复,于是减去3篇,只剩下53篇。)同时我还更正了OG上几个明显的错误(详见文后附录)当然,我还做出了方便大家理解文章的参考译文,附在文章的后面。 在这53篇由ETS出的文章没有做完之前,我们实在不应该花时间在任何其他的题目之上。我有时候甚至会对着我的弟兄们高呼:“没有把这53篇做3遍,你好意思上考场么?你好意思花钱在任何一本垃圾书上面么?[6]” 另外,如果你正在准备iBT-SAT-GRE的作文部分或者写留学文书,也应该仔细的琢磨一下这些文章:经过ETS打磨的文章,无一不是精妙绝伦,极具模仿价值。常常有同学拜托我帮她(他)写PS,也说起自己的句子怎么看都像是小学生写的(尽管用上了GRE里面的单词),于是会随口问我“勇哥,您的写作能力是怎么训练出来的。”我说,“看呗,看呗:托福文章看多了,写作能力自然就提高了。” “这ETS的这些文章真的那么好?”。每当听到这个问题,我都会装做赵本山的样子来一句“谁用谁知道~~” 文勇 欢迎进行未删节的转载|且不必告诉我你转载到哪里去|都是一个战壕里面的弟兄啊… 告诉大家一个好消息,本文档中的TPO1-TPO9,以及在线测试题和官方模考题目的解析已经在市面上可以买到了!(好吧,我承认以下显然是广告部分): 这本《托福真题详解-阅读分卷-第一册》是给弟兄们现在市面上可以获得的TPO1-TPO9阅读部分的文章解析,题目解析,中文翻译和每篇文章的必备词汇:文章解析是为了让大家养成从整体抓文章结构的感觉,题目解析是为了使大家能够在做完题之后知道正确选项为什么对,错误选项为什么错——并且因此来培养良好的做题思路,中文翻译是为了帮助大家扫除那些自以为理解对但实际理解有误的句子,在每篇文章后面配上必备词汇无非是为了节省大家的一些查单词而已。 另外,这本书还包含了一张CD(我想你可能第一次听说阅读书...
