上蠕动。
Although sperm are constantly being made within the testicles, should the
man not ejaculate for some time, his testicles won't explode. The
spermatozoa are simply re-absorbed into the body. This is important for
vasectomy patients because they simply have their 'tubes cut' and sperm is
still produced. Should excess sperm not be absorbed, it would not be long
before the patient's testicles were dragging along the ground.

发帖数: 2202 | 5 Infinite monkey theorem
From Wikipedia, the free encyclopedia
Given enough time, a chimp punching at random on a typewriter would almost
surely type out all of Shakespeare's plays.
The infinite monkey theorem states that a monkey hitting keys at random on a
typewriter keyboard for an infinite amount of time will almost surely type
a given text, such as the complete works of William Shakespeare. |

发帖数: 19317 | 9 这个小side trip是简要的讲人类演化的。
our understanding of this area is moving forward rapidly, as new evidence
emerges and hypotheses are tested, confirmed, discarded, or modified.
这里再次提点到，演化的理论，树形结构的分支，如何对物种，特别是近亲物种进行分
类，如何分析突变的转折点，这些都是经过反复的比对校正的，并不是单独依靠某个生
物大牛个人的观点看法的。
在这个小节的讲义里面第一页，树形结构上面仅仅给出了chimp和homo的分支。但是从
第二页里面，我们可以看到，根据现在能掌握的化石资料，其实homo里面还分化出了不
同的类别。
我不知道这些类别到底在生理结构和DNA组成上面的分离有多大，但是我的感觉是虽然
这些不同的homo有各自的名称，但是应该没有产生有足够影响力的分离，所以没有在树
形结构上作为独立的分支被列出。
我个人感觉，会不会好比今天的不同人种，虽然各自有各自一定的生理特征，也被分为
黄种人，白种人，黑种人这样的分 |

比如说，如果是融合的话，理想的证明是在二号染色体上找到两个着丝粒（
centromeres，在染色体的中部），但是，Ken Miller所引用的那篇文章说：one of
the two centromeres became inactivated (2q21, which corresponds to the
centromere from chimp chromosome 13) and the centromeric structure quickly

发帖数: 2255 | 18 俺说的是genome比较，这里面是有染色体多少的区别，基因次序的区别，包括和猩猩的
比较，都是测序后分段比较用算法来彼此分段match的。
UIUC首先完成的人猪比较并有下述报道：
http://www.aces.uiuc.edu/Discover/discover37.cfm
这上面说了人类的genome切成173片可以拼出一个猪的genome来， "Everything
matches up perfectly. The pig is genetically very close to humans."。
但俺没有找到更详细的文章，而且类似的研究后来都语焉不详。比如中国-丹麦的猪基
因研究在2005年测序66%后报道人猪非常接近后，也没有下文了。
俺还看到猪人genome相似度超过98%，大于人和chimpanzee的95%。但这个资料要找一找。
至于人和大猩猩：

发帖数: 1648 | 20 我相信大多数认真阅读全段【寻找科学亚当、夏娃】文章的人，都能看出作者是如何推
出下面的结论A的。
http://www.bydnacoding.org/CHT2-P1.html
不过会认真阅读这四页的人很少，我总结一下。
论据
1 现今全人类都是一位女性（线粒体DNA夏娃）的后裔。 （因为所有人mtDNA，高度类
同，而与其他任何动物都很不同）
2 现今全人类有一位共同的男性祖先（Y染色体亚当） (因为所有男性ZFY基因区包含
的729个DNA字符代码序列完全相同)
3 现今全人类的2号染色体长臂的2q13–2q14.1位置上，都有一段“789个碱基字符的序
列”，它是男人和女人都有的标记。 所有人完全相同
结论A：
Y染色体亚当和线粒体夏娃，他们都是那唯一一对父母的后裔。这一对父母就是人类起
始的一男、一女，我们可以称他们是“科学亚当”和“科学夏娃”，他们是从你、我血
液中追寻出来的源头。
1+2+3同时满足，推出结论A, 1+2+3是这一结论A的充分条件 (当命题「若A則B」为真
时，A称为B的充分条件)

如果你关注的是纯计算TFBS prediction，我觉得已经很准确了。如果没记错，ENCODE

但是坦白说从纯biology角度，现在大家完全不满足于binding site；
1. Binding doesn't mean function! 好文章现在都要求证明binding后是否调控了
gene expression change
2. 蛋白-DNA和蛋白-蛋白作用非常复杂，所以很多ChIP实验本身就值得质疑，很多猫腻
3. ENCODE project当年豪言说根据他们的研究human genome 80%都有function，当时
受到了批评和质疑
