- 2. Tiny fossils reveal how shrinking was essential for successful evolution
Scientists have discovered that mammals successfully evolved over the years by getting smaller in size.
- 3. Genetic toolkit gives periwinkles seashore advantage
Periwinkles, struggling to survive the seashore battleground, have developed a genetic toolkit to help them adapt to different environments, a new study shows.
- 4. Meet your inner lizard
An ancient little lizard-like creature from the Scottish Borders is the missing ancestral link between human beings and the fish we evolved from millions of years ago.
- 5. The rise of mammals

- 7. Podcast: The effects of metal pollution on fish
This week in the Planet Earth podcast, Jamie Stevens and Josie Paris of the University of Exeter explain how some fish have adapted to heavily polluted rivers in southwest England.
- 8. Podcast: Of sewage and superbugs
This week in the Planet Earth podcast, Elizabeth Wellington and Greg Amos of the University of Warwick explain how sewage treatment could be helping spread highly drug-resistant bacteria around the environment.
- 9. Podcast: The evolution of the British peppered moth
This week in the Planet Earth podcast, Ilik Saccheri and Arjen van 't Hof of the University of Liverpool describe how the British peppered moth changed from peppered to black during the Industrial Revolution in northern England.
