Question 1:

有一种药物，1000例绝症里面只能治愈1例，请问统计学上显著否？这个药物是否值得开发？能用否？总比治不好强吧？

If there is a drug, by which only one case in 1000 cases of fatal disease can be cured, I ask whether the differences are statistically significant? Is the drug worth development? Better than nothing?

Question 2:

有单细胞生物变成多细胞生物的，有单细胞生物保持单细胞状态的，那么，有多细胞生物变成单细胞生物的吗？

如果有，我支持中性演化学说就多一点；如果没有，我还是相信“进”化有一个总体的方向性的。

There are single-celled organisms which become multi-cellular organisms, there are single-celled organisms which keep single-cell state, then, is there any multi-cellular organism which evolve to a single-celled one?

If yes, I support a little more on the neutral theory of evolution; if not, I still believe that EVOlution has a general direction.
