Sorry, I am doing some work in the lab. I did not mean that there is not
enough direct evidence to support evelution, it just cannot be proved or
dis-proved by traditional experimental approaches in the lab. You can not
make specific hypothesis then carry on experiment to test your hypothesis.
All those things happened thousands or millions years ago, and observe one you
also need to wait for thousands maybe millions of years.
It just like in high energy physics, you cannot see certain short life
particle, but you can deduce it from the particles it becomes, and by certain
law you can even caculate the life-time of the original particle, the
momentum, mass, so and so on. However, in biology, those theory is still not
very mature, even biologists themselves are not always agree on some of the
caculations they did based on fossil record. I think that is the weak point
of this theory.

Personally, I am strongly for this theory, because it is simple, and it can
explain almost all exsiting observations without much modifications. However,
cannot test in the lab is still a shortcoming of the theory, very much like
Enistein's general raletivity. Most people think it is true, but no
hard-evidence to fully support it. Just my personal opinion.
