Actually, the exchange goes like this:

Professor: Scientists say that evolution is the best current explanation for life's diversity
Student: How do they know this?
Professor: Because the data that we have is best explained by modern evolutionary theory
Student: Does this mean we know how every organism and every biochemical system evolved?
Professor: No. But it's a start.


  First, I'm assuming this is Andy Groves. If not, I would appreciate knowing that.

I would really prefer to discuss the question that I started with, which referred to the evolutionary mechanism by which microglial cells might have evolved.

However, since you struck my funnybone, here's my experience:

Student: I would be interested in knowing what you mean when you use the term evolution. Do you simply mean "change over time" or do you mean "change in gene frequency as a result of natural selection" or do you mean "the accumulation of fortuitous mutations over time as a result of natural selection leading to new adaptations, structures and processes".
Professor: Next question.
Student: OK, I'll move on. Perhaps you would care to describe some of this data that you refer to? Is it empirical data, in the form of observations or experiments and how does it support whatever it is that you call evolution?
Professor: <<sound of crickets chirping>>
