Introduction

This unit provides an introduction to the evolution of mammals.

We will be considering Darwin's observations on a great many mammals, and how he noticed that species fell into natural groups. We take as an example the evolution of one particularly interesting mammal, the whale, and look at evidence both from fossils and from DNA to see which other mammals are most closely related to whales. We see how the evidence from these two very different sources points to the same relationship and

Pierce Biotechnology
The pedagogical value lies in its concise description of the various analytical derivatization reactions and reagents used for gas chromatography. This site gives a nice description of the various derivatization reagents and what type of analyte they are used for. One of the few, if not the only, ASDL sites dealing with derivatization.

Hydrophilic Interaction Chromatography, HILIC/SEC, HILIC/SXC
This site provides good background and operational parameters for the use of a specific type of chromatography, hydrophilic interaction chromatography. Pedagogical value, however, is probably only directed toward a graduate/advanced course in separations. This document provides a very clear explanation of operational parameters and mode of operation for HILIC. Very readable!

5.6 Land and water pollution

In this section we will just take a couple of examples that show how easy it is to expose ourselves to long-term damage inadvertently. Pesticides, developed to control insects and other vermin, can increase agricultural productivity. Although pesticides were originally hailed as one of the wonders of modern technology, it was quite quickly discovered that there was a downside to their widespread use. One problem was that of bioaccumulation. Pesticides tended to be stable chemicals and

3.3.1 Sequence of events

It was important to establish the precise sequence of events leading up to and during the collapse. From which part had the collapse started? Why had so much of the structure been destroyed? Was there any prior warning of the failure? What part had the weather conditions at the time played?

Eyewitnesses were plentiful, and each had a different perspective of the bridge as it fell. There were some common parts to their statements. Most of the witnesses, especially survivors from vehicles
