As the amount of data that can be brought to bear on a task grows, so too does the difficulty and importance of making the best use of our data. A basic question in statistics is to determine how much data is needed to estimate various properties of one or more probability distributions. We consider the fundamental properties of support size, entropy, and the distance between two distributions.

In the second half of the talk, we take our inspiration from biological evolution -- a natural process that, from vast amounts of data and complexity yields surprisingly effective results. In this talk we formulate a notion of "evolvability" for functions with domain and range that are real-valued vectors, an appropriate way of expressing many natural biological processes such as protein expression regulation.
