Next steps
Fossils are a glimpse into the distant past and fascinate young and old alike. This unit will introduce you to the explosion of evolution that took place during the Palaeozoic era. You will look at the many different types of creatures that existed at that time and how they managed to evolve to exist on land.

1.2 Artificial selection
In the 18th and 19th century evolutionary biologists, including Darwin, emphasised the similarities between natural evolution and artificial ‘ improvement’ of livestock under domestication. They believed that studying domesticated animals and plants could illuminate the mechanisms of natural evolution.
3.1 Introduction
This unit examines Hume's reasons for being complacent in the face of death, as these are laid out in his suppressed essay of 1755, ‘Of the immortality of the soul’. More generally, they examine some of the shifts in attitude concerning death and religious belief that were taking place in Europe at the end of the eighteenth century, through examination of this and other short essays.
3.2 Person–job fit
Does the recruitment and selection process fill you with dread? Discrimination and equal opportunities legislation can make this area feel like a minefield. If you are faced with appointing a new employee, then this unit will provide a straight-forward guide to the process: from writing job descriptions to finally assessing who to appoint.

3.1.1 Option 1: Don't use the diagram at all
Working with diagrams is essential for students of science, technology, engineering and mathematics. This unit is packed with practical activities and tips which make learning from and with diagrams more enjoyable and rewarding. One part of this unit deals with the reading of diagrams and the other part with the drawing of diagrams.
3.6 Reflecting on dyslexia Throughout this unit, dyslexia has been evaluated as an example of ‘abnormality’, a difficulty, a problem in need of an intervention. However, research has shown that some adults with dyslexia are distinctive, not just in their difficulties, but also in their increased levels of creative reasoning compared to ‘normal’ people (Everatt 1997). West (1997) reports that Nicholas Negroponte, the founding member of the Media Lab at the world renowned Massachusetts Institute of T
Effects of fertilizer and pesticide use
When used properly, fertilizer and pesticide application can help protect crops and encourage their growth. However, fertilizers and pesticides can run off into bodies of water and contaminate water sources.

Worker ants in the desert
Ants are from the same group as bees. They have three body segments and six legs, but lack the wings and are much smaller than bees.
Weight lifting
Weight lifting is beneficial because it builds muscle. Muscles aid in burning fat and calories. Toning your muscles helps you move more efficiently.
