Perhaps you should define as to what you think evolution is, before you say you don't see any.
I thought I did. E. Coli still remainds E. Coli. Perhaps I should have said I don't see anything significant about this study. I have no problem accepting that genetic mutations occur. However, it seems that this study is inferring that this is the first witnessed proof for evolution. I would be interested at the lead researchers definition of evolution.
It's a fair request that you ask. I looked it up. Good ol' Google:
I looked at other pages as well but it seems the most standard definition I could find was on the above page and read:
"Evolution is a process that results in heritable changes in a population spread over many generations."
Also reading further into other articles about this study it would seem that Richard Lenski and many other evolutionists hold this study as a holy grail (in comparison to other studies before it) in the debate of creation vs. evolution. If all evolution is defined as being is the heritable change in a population spread over many generations then why would there be any debate at all?
Perhaps the debate is mearly by what process did life evolve. If this study holds any significance in that debate I am not seeing one. If this study is of significance in the study of mutation then I suggest there are more clear and abundant examples elsewhere.
20 years of study for what?
I digress a bit from the original request of a definition but I believe you should now understand the point I am making.
